Boasting a great outdoors lifestyle and the greatest variety of native wildlife (dugongs, wild dolphins and koalas just to name a few) of any capital city in Australia, Brisbane offers an impressively diverse menu of leisure and recreational activities. From art lover to outdoor adventurer, Australia’s third largest city caters to all tastes.

Along with the cosmopolitan and urbane offer of world-class shopping, restaurants, nightlife, culture and entertainment, Brisbane lives and breathes outdoor experiences. From kayaking on the river, to cuddling a koala, to hand-feeding wild dolphins at sunset, visitors can enjoy a range of unique and memorable Australian experiences.

Best known as the home of iconic tourism destinations like the Great Barrier Reef, the Daintree Rainforest and Fraser Island, Queensland is a state blessed by both beauty and bounty. Held fast in the hearts of many Australians as their favourite holiday destination, Queensland is also a state rich in resources, talent and innovation. From white sandy beaches to red desert reaches, Queensland is a state of contrasts. City, coast or country it’s got something for everyone. www.visitbrisbane.com.au

PRESIDENT’S MESSAGE

(although that would be good), but rather to participate in the process that ensures the Association has planned where it wants to be and is geared towards achieving those goals in a realistic timeframe. The release of the Strategic Plan is one step in the process.

Allan Sterling President Hi All, Welcome to 2013, I trust all our members and readers have had a happy and safe start to the New Year and I trust our members have been safe from the recent natural disasters around Australia.

Through the efforts of the members and staff of the Association, we are primed to continue our growth throughout 2013.

What do I hope to achieve in 2013 as President? I would like to say I can achieve a lot, however the reality is that 12 months is really only a short period of time. (I am already 17 % of the way through my term as President.) The role of the President is not so much to achieve something momentous

p.6 CORROSION & MATERIALS

Within the strategic plan I am most passionate about education and training. This passion has been driven by the understanding that one cannot progress within an organisation unless you can find someone to fill your shoes. In other words, in order to progress you inevitably need to make yourself redundant. Through my years of employment I have always been encouraged to continue my education and personal development. To me this is important for everyone in every organisation.

For those of you who know me, you will know that I am more focused on the practical aspects of corrosion prevention. I am not denigrating those that undertake the tremendous amount of good quality research work; I am just more focussed on practicalities. The research works need to be developed to the point where the processes can be readily implemented outside the air conditioned laboratory.

I am looking for ideas to enable the Association to develop a genuine interest in corrosion prevention or to draw people into the Association.

I quite enjoy presenting the Introduction to Cathodic Protection course as it opens the eyes of the course participants as to what we are

trying to do. I am looking at ways to incorporate more practical aspects of corrosion knowledge and control within the annual conference framework.

The aim would be to draw people into the Conference and Exhibition who would not normally get an opportunity to participate. With good promotion this should bring in people who may otherwise perceive the Conference as being for the “boffins” only.

I am also exploring ways we might recognise innovation within our industry. Examples of such innovation would be the development of inorganic zinc coatings which are now a common starting point for many coating systems or development of the DCVG (direct current voltage gradient) coating survey technique which has become the pipeline industry standard for coating quality assurance after installation.

On a sad note, I recently attended the funeral of Dr Paul Schweinsberg. Paul was a Past President of the Association and a Corrosion Medal recipient. Paul was active in the Association over a long period of time and will be sorely missed. Paul was very proud of winning the Corrosion Medal to the point where it has been buried with him. The ACA was very well represented at the funeral service with quite a number of members paying their last respects.

Finally, if you want to grow tall remember to stand in that cow manure.

Don’t forget to use both feet; otherwise you will develop a limp.

CEO’S MESSAGE

Constitutional change a response to growth, complexity and the fundamental needs to be transparent and accountable 2013 promises to be a year of further growth for ACA with a number of new member benefits being developed for delivery. Importantly, the long awaited review of the association’s constitution is scheduled to be completed in time for members to consider at a special general meeting to be conducted in conjunction with the conference scheduled for November.

Membership now exceeds 1800 and the possibility of surpassing 2000 is well within grasp.

ACA’s constitution originates from the birth of the organisation more than 50 years ago. Certainly, the organisation has changed since those who founded the ACA set down what and how the organisation does. Methods which were appropriate for their day in the sixties are not necessarily suited to the membership and regulatory demands now encountered.

Importantly, the objects for which ACA was founded are largely still appropriate to the needs of the organisation today. The basics of what

ACA does remain largely unchanged and in the review of the constitution it is anticipated that refinement, rather than change will be the focus for ACA’s purpose.

Also key to the continued success of ACA is the ongoing recognition of the important role that Branches play in delivering services to members at a local level and as the source of the ACA’s volunteer leaders.

So if the underlying features of ACA’s governance are sound, why then is there a need for change?

Operationally, ACA’s direction is now determined by its strategic plan. What has been known as the Operations Committee now acts as a Board and the role played by staff has increased significantly. If a Board is to be effective it must have the capacity and responsibility to make decisions in the best interests of the organisation being able to promptly respond to the needs of a growing organisation. Importantly, a Board must be able to attract directors with

the requisite skills necessary to govern ACA, protect the interests of members and to continue to improve member benefits. So it is likely there will be reform in this area which will place ACA in the best position in order to meet the challenges of a regulatory environment which is increasing in complexity, which allows for considered “business” decisions to be made promptly with accountability and transparency and which will increase the value of ACA membership regardless of the membership classification held – individual, corporate, student, etc.

Several rounds of consultations are fundamental to the development of a constitution which is suited to the needs of ACA as it moves forward in the 21st century. By the time members are able to read this column in print in Corrosion and Materials, the first round of those consultations will be underway.

ACA AWARDS

2013 ACA Awards It is now a good time to remind authors as well as potential authors that several ACA Awards are open for applications.

Please refer to the ACA website for further details on all of the awards below.

C&M Best Paper by an Early Researcher Award (closes 30th June 2013) The C&M “Early Researcher Best Paper Award” remains open until June 30th 2013 for those potential authors with less than three years post-graduate research experience. This award has been instituted by the ACA for the best Technical paper submitted for publication in Corrosion & Materials during the year and very often authors can take advantage of the comments and discussion which have arisen as a result of their presentation at the conference to modify and hopefully improve the papers so that they can be submitted as original papers for publication in the Research section of Corrosion & Materials. Papers accepted (after going through the standard refereeing process) for the Research Section qualify for inclusion in the list which an author or his or her institution can submit for the A.R.C. “Excellence in Research Australia” list of recognised research publications. The ERA Identification Designation for Corrosion & Materials is 123306 and the normal “Field of Research” is 0912 Materials Engineering, but 0913 Mechanical Engineering and 0306 Physical Chemistry are also accepted by the ARC. The competition is not restricted to papers that have been modified after presentation at the Annual Conference. Any paper, by an “early researcher”, that is submitted and accepted for publication in the Research or Professional Practice

sections of Corrosion & Materials is eligible for the award which consists of free registration for the annual conference of the ACA and AU$1,000 as a contribution to the expenses of attending the conference. The author must be designated as the “Lead” (first named) author of the paper, but may have co-authors who may include his or her supervisor.

AC Kennett Award (closes 31st August 2013) The ACA grants the AC Kennett Memorial Award (which consists of AU$1,000) to the best paper written on non-metallic corrosion and presented at any technical meeting, conference or symposium held under the auspices of the ACA or published in Corrosion & Materials.

While a degree of discretion is allowed, the key aspects of “corrosion” and “non-metallic materials” must dominate for a paper to be considered.

Applications must be received by no later than the 31st of August 2013 and must be accompanied by a statement of 100-150 words in support of the application as well as the complete text of the paper. Please refer to the ACA website for details.

ACA Student Research Award (closes 30th June 2013) The ACA Student Research Award is presented to full time post graduate students in recognition for work on fundamental or applied research in any branch of corrosion during the course of a higher degree in Science, Engineering or a related discipline. The award is judged upon significance of the work to the community, originality and soundness of the research.

To be eligible, applicants must submit and have accepted a full manuscript into the 2013 conference proceedings, with view to it being presented. The successful applicant will receive AU$2,500 with the intention that the Award be used to meet attendance costs at the annual ACA Conference of that same year. Applications and submission of the full paper must be made by 30th June 2013.

JPCL Editors’ Award Winners Congratulations to lead author Rob Francis along with co-authors Gianni Mattioli and Stuart Smith on winning a 2012 JPCL Editors’ Award. Their paper entitled “Relining Potable Water Tanks: Research and Field Work” published in the May 2012 issue of JPCL was selected based on its organisation, originality and importance to the protective coatings industry.

Rob, Gianni and Stuart were recently recognised at the SSPC 2013 conference San Antonio, USA during the SSPC Annual Business Meeting & Awards Luncheon on Monday, January 14, 2013. Unfortunately they were unable to attend the awards luncheon, but

ACA Past President Peter Dove was in San Antonio and received the award on their behalf.

The published paper was based on their paper presented at the ACA’s Corrosion & Prevention 2010 conference and the paper is available for ACA members to search and download on the members only section of the ACA website. A summary of the paper is below: A number of Melbourne Water’s steel potable water tanks have suffered severe corrosion of the base plates due to salt contamination of the limestone bedding material. Repair options include installation of a

reinforced epoxy lining which provides mechanical strength in addition to corrosion protection. This paper looks at the issues involved in selecting a lining that provides the required strength and flexibility as well as resistance to and compatibility with potable water, including a discussion of candidate glass reinforcement materials. It describes the practical issues of installing the lining including environmental control, surface preparation and application. The paper concludes with the results of a recent inspection which has showed the lining is performing admirably.

New world-leading Manchester lab to tackle global cost of corrosion Scientists opened a new world-leading laboratory in Manchester, UK on Monday 17 December 2012 in a bid to help tackle the cost of corrosion.

doctoral researchers and PhD students have also been directly employed to work on projects with active AkzoNobel technical involvement.

The AkzoNobel Laboratory of Corrosion Protection at The University of Manchester is the result of a fiveyear landmark strategic partnership between the largest global paints and coatings company and one of the UK’s top universities.

Research conducted at the new facility will address a number of key challenges that will enable AkzoNobel to develop optimised product platforms, including:

The University of Manchester is home to the world’s largest academic unit dedicated to the study of corrosion.

Its partnership with AkzoNobel commenced in April 2012, to allow for vital work to be undertaken to help tackle the annual $3 trillion global annual cost of corrosion, accounting for over 3% of the world’s GDP.

hat are the coating-substrate W interactions which prevent corrosion?

As well as allowing for the opening of a brand new laboratory to help tackle corrosion, the partnership has also resulted in the appointment of Professor Stuart Lyon as the AkzoNobel Professor of Corrosion Control, based in the School of Materials, to oversee an agreed research programme to be supported by research staff within The University of Manchester. Several post-

p.14 CORROSION & MATERIALS

partnership with AkzoNobel will enable The University of Manchester’s Corrosion and Protection Centre, based in the School of Materials, to solve key scientific challenges in how best to control corrosion and hence to minimize the use of scarce resources in an environmentally sustainable way.

hat causes some paints to prevent W corrosion and others to fail?

ow to predict the lifetime H of coatings ow can corrosion be detected before H it is visible?

Finding solutions to these challenges will allow AkzoNobel to develop improved design rules for coating systems for different substrates in different challenging environments, accelerate development of new chemical systems and ensure the integrity of AkzoNobel’s assets.

Stuart Lyon, the AkzoNobel Professor of Corrosion Control, said: The research

Vale It is with great regret that we inform you of the passing of Dr. Paul Schweinsberg who was well known to many of you. Paul had an extremely interesting and successful career being educated at Sydney Technical College, University of NSW and the University of Queensland where he obtained his PhD through the Dept of Mining and Metallurgical Engineering. Paul settled in Brisbane, taking up a position as Senior Lecturer in Chemistry at Queensland University of Technology in 1965. He was a Chartered Chemist with the Royal Australian Chemical Institute whilst his academic focus was electrochemistry with specific application in corrosion science.

Paul furthered his corrosion interests through a long-standing 25 year involvement with the Australasian Corrosion Association. This was at both Branch and Australasian committee levels. He held roles as Branch Secretary, President, Education Officer, Senior Vice President and nationally as Australasian Education

Director and Australasian President. As well, he achieved numerous accolades through the Association including the A.C. Kennett Award, receiving their Corrosion Medal and delivering the P.F. Thompson Memorial Lecture in 1997.

Paul had a reputation for generosity in giving and propelled many of the people he came into contact with into very successful careers through his guidance and knowledge.

During his working lifetime, he travelled extensively, visiting major international academic institutions and linking up with a number of collaborators working in the corrosion field. His work covered fundamental corrosion kinetics as well as extending to applied problems of corrosion which came through his consulting. Paul was a prolific educator throughout his entire life imparting his knowledge and wisdom to untold numbers of people through graduate supervision, publication of 39 refereed journal articles, 23 conference presentations and numerous book chapters and educations manuals which are still in use today. In the early years of corrosion education in

Australia, Paul co-authored a short course training manuals on “Basic Course in Corrosion Technology” and “Power Station Corrosion” which became local undergraduate and postgraduate texts. For many years up until 2012, he was editor for the Queensland Branch newsletter where his keen eye was invaluable. Though Paul formally retired in 1999, he continued his research interests at the QUT as an Adjunct Professor until 2012 and despite failing health, coauthored a paper on kinetic modelling in the most recent (Nov 2012) ACA Conference, and has a current paper to be submitted by his co-author shortly on galvanic corrosion.

One of Paul’s greatest achievements was being a dedicated husband of 50 years to Val and a cherished part of his extended family. For many of us we will remember him as a close colleague and a dedicated friend to whom we owe much of our success. Paul was a quiet achiever and many of his contributions and our memories of him will be alive into the future.

YCG Victoria end of year social event The YCG in Victoria capped off the 2012 year with a fantastic event at the Richmond Union Bowls Club Tuesday, 27 November. Despite 25 mm of rain Melbourne had that morning, over 25

people attended to celebrate the end of what has been a hugely successful year.

It was great to see academics (Monash and Deakin both well represented)

mixing with consultants, materials suppliers, contractors and asset owners. It is events like this that make the YCG worthwhile by helping facilitate relationships between a large cross section of industry as we all work together in the future to mitigate corrosion.

A BBQ fired up along with drinks in the private outdoor function area but unfortunately due to the torrential downpour that morning, this meant that the greens were unavailable for play. The Bowls Club hospitality was fantastic however, and when the night turned cool there was table tennis inside the function rooms.

The YCG Victoria will endeavour to run the same event next year, but actually get some bowls in!

YCG WA Kalgoorlie technical night The WA YCG continued on from its Kalgoorlie site visit to conduct a technical night in the mining town on the 6th December. The event consisted of five presentations on the topic ‘Corrosion Mitigation Through Design’ which attracted 28 attendees including contractors, suppliers, consultants, academics and asset owners. The aim of this particular technical evening was to raise awareness of corrosion through the illustration of some seemingly poor design and some ideas on how to rectify the issues.

The first presenter was Giles Harrison of Extrin Consultants who introduced the concept of corrosion mitigation through design by first showing everyone a brief cartoon strip detailing an experiment involving monkeys, a ladder and some bananas. Giles presentation added that generally speaking the majority look at designs from various points of view; structural, cost, installation, drainage, aesthetics

but rarely ever from a corrosion perspective. This issue is even more pronounced in the mining industry in that plant design rarely differs from the “she’ll be right mate” and “we done it like that before mate” attitude.

The second presenter was Stephen Foley from Newmont. As the Senior Civil / Structural Engineering Advisor for Newmont within the Asia Pacific operating region, Stephen has been able to witness the challenges faced at Newmont’s operations and test the concept that ‘no site is a silo’. Next was Wayne Gray from Extrin Consultants with his presentation discussing the basics of Galvanic Corrosion and how to alleviate the affects.

Yezdi Talati from Rapallo gave a very interesting talk on the inspection of pressure vessels (AS 3788 - 2006 pressure equipment—In-service inspection). Particularly interesting was his take on crevice corrosion

to name plates on pressure vessels encouraging everyone to ensure that all crevices are sealed to ensure the name plate is readable in years to come.

The last speaker was Shaun Traves from Kalgoorlie Consolidated Gold Mines who gave a presentation on his learning’s regarding conveyors and pump bund design in the mitigation of corrosion. Shaun’s simple yet very effective solution to conveyor leg stub corrosion was particularly interesting.

By simply raising the plinth the steel section is lifted out of the corrosive wet conditions; an oversight during the original design some years previous.

The WA YCG thank Giles Harrison for organising the event, Kaustav Bandyopadhyay who was the MC, all of the speakers and to Peter Farinha for giving up his time to come to Kalgoorlie and have a chat to the group about the benefits of joining the ACA and the ACA mining industry group.

YCG off to a flying start The reformation of the ACA Young Corrosion Group (YCG) is off to a flying start as planned. During an extensive planning day (late 2011) with a new steering committee, a new framework was established along with an operational plan to implement the objectives set out in the framework.

The plan was implemented extremely well during 2012 thanks to the YCG Steering Committee and their YCG Sub Committees with the financial support of the ACA Foundation and ACA Branches.

The key objective of the YCG is informing a wider spectrum of young (under 35 years of age) corrosion industry personnel about the ACA and to attract more young people to become involved. The YCG also ensures the future survival and function of the ACA and provides a forum for professional interaction, support and networking for young corrosion industry personnel.

In its first year, the YCG coordinated 12 events in 2012 including the inaugural Future Leaders Forum and the YCG function at the ACA conference. The locally organised events included: New South Wales 14th August: Technical Evening entitled ‘Corrosion in Action!’

p.22 CORROSION & MATERIALS

6th October: Site Visit to BlueScope 2 Steel and Industrial Galvanizers.

New Zealand 30th August: Technical Evening Annual NZ YCG Event.

South Australia 8th August: Site Visit to PMB Defence Engineering.

Victoria 28th March: Technical Evening on Cathodic Protection and Protective Coatings.

1st June: Technical Evening on 2 Durability Design and Corrosion Monitoring for Engineers.

7th November: Bare Foot Bowls End 2 of Year Social Function.

Western Australia 4th May: Technical Evening entitled ‘Careers in Corrosion- the Different Paths into the Corrosion industry’.

8th-29th July: Site Visit to the Super 2 Pit in Kalgoorlie. th December: Technical Evening 6 entitled ‘Simple Design Alterations to Mitigate Corrosion in Mining’.

A summary of these events have been published in Corrosion & Materials as well as the ACA YCG Facebook

page which has over 120 ‘Likes’. In total, these events attracted 400 YCG attendees, growing the ACA’s YCG database considerably which enables the ACA to inform this database of Conference Scholarships funded by various ACA Branches, future events, student awards, etc.

As listed above, the YCG aims to provide professional and personal development opportunities via presentations and site visits as well as providing a social element to assist the YCG in establishing a network of peers.

Given the first year’s successes it is important to build on this momentum and further develop the YCG framework and operational plan moving forward in 2013 and the years to come. It is planned that the YCG Steering Committee will meet in early 2013 to review 2012, plan for 2013, develop their sub committees further and to expand the geographic area of YCG events.

A well-deserved recognition to the YCG Steering Committee in Erwin Gamboa, Dean Ferguson, James Wu, Giles Harrison and Sean Ryder for their contribution to the future survival and function of the ACA via the YCG.

SSPC UPDATE

SSPC Update During 2012, The ACA conducted recruitment and training of potential Lecturer/Assessors for the new SSPC Applicator Courses: 7 Dry Abrasive Blaster Certification C C12 Airless Spray Applicator Successful completion of these courses will give an applicator a certification that is internationally ‘recognised’ in the Corrosion Industry.

The ACA was fortunate to field 5 candidates as potential lecturers in the initial round of training.

The training by necessity had to be conducted at two venues in Melbourne, Holmesglen Conference Centre for the classroom activities, while the practicals were conducted at Eddy Batur’s Industrial Coating facility at Hastings.

All candidates were required to undertake an intensive training and assessment program which was conducted by Dan Buelk, an accredited SSPC Train the Trainer from Portsmouth, Virginia and Barry Hodder, the Education and Training Manager for the ACA. Dan brought an extensive knowledge of SSPC and the courses on offer which he enthusiastically passed on to the candidate lecturers/assessors. Barry was able to assist with presentation techniques drawing from his years of experience as an accredited trainer and presenter.

The candidates undertook the training in 2 x 4 day blocks running consecutively (back to back). Classroom sessions were undertaken by each of the candidates who were then required to present these sessions to their peers, under the watchful eyes of Dan Buelk.

Typical subjects presented by the candidates were; ggregate Types and their impact on A surface profiles Environmental conditions Airless spray equipment Safety requirements, and much more After the completion of the classroom aspect of the course, the candidates were required to conduct training and assessment on their practical abilities in both Abrasive Blasting and Airless Spray. This was accomplished by each candidate preparing and spraying a metal test panel which must meet the requirements as laid down by the standard ASTM D4228-5 (2012). The panel has some remarkable features, which are seen in the photograph below.

The panel consists of a sheet of carbon steel approx. 1.7mtr square. Fixed to the sheet is; I Beam (30cm x 30cm) 10cm pipe (30cm in length) 5 x Nut and Bolt (2.5cm x 10cm) ‘Flower Box’

Candidates were assessed on their practical skills when abrasive blasting and operating airless spray equipment.

This involved the candidate ‘walking’ the assessor through the following; quipment Identification E Equipment Set Up Equipment Nomenclature Safety Inspection of ALL Equipment Safety requirements for work processes Personal Safety Work site Safety Environmental Safety Candidates must also demonstrate personal knowledge related to each phase of the application, which includes the requirement to record precise information and nomenclature that is defined by existing Industry Standards and WorkCover.

Due to the intensity of the program, lecturer candidates were by necessity required to participate both in workgroups and function as individuals in every aspect of the assessment phases.

A ‘Candidate Applicator’ is required to complete the course by attending a one day classroom theory session and then demonstrating their skills in an actual worksite environment while operating/applicating in either of both of the Certifications; 7 Dry Abrasive Blasting, and C C12 Airless Spray Basics

Dan Buelk (in Red) is verifying the accuracy of the written records with lecturer/assessor candidate Sandy McPherson.

SSPC UPDATE

At the completion of the first round of Lecturer/Assessor Courses, an opportunity presented itself at the recent Annual Conference in Melbourne, to formally present two of the SSPC Lecturer/Assessors with their Certificates of Accreditation and supporting documentation.

Making the presentation to Graham Carlisle and Sandy McPherson on behalf of both SSPC and the ACA were; Bill Shoup the Executive Director for SSPC and Peter Dove, the outgoing President of the ACA. Industry has welcomed the introduction of the certification courses as they will ensure that very high standards are achieved by the applicator. Additionally the

requirement to recertify will ensure applicators are continually meeting the high standards of the accreditation.

SSPC C7 Dry Abrasive Blasting Certification C7 is designed for contractor and applicator personnel who wish to obtain certification or others who wish to learn about dry abrasive blast cleaning of steel. It covers principles of surface preparation, surface cleanliness, surface profile, dust and debris control, and abrasives.

marine environment. Candidates are certified through a brief certification written exam and a practical handson skill assessment. This course is designed to train and certify marine/ industrial applicators to operate airless spray equipment.

review The Australasian Corrosion Association Inc would like to thank all delegates for their attendance and participation at the Corrosion & Prevention 2012 Conference in Melbourne.

We believe everyone had a great time and enjoyed catching up with old friends and meeting newcomers to the conference. Thank you to all the speakers for their contribution to a very successful programme, in particular the plenary and invited speakers.

Corrosion & Prevention 2012 which was held on the 1114 November 2012 at the Crown Conference Centre was the largest ACA stand-alone conference ever conducted

p.30 CORROSION & MATERIALS

attracting 573 delegates including a large international delegation from the USA, UK, Libya, Kuwait, Sweden, China, UAE, India, Germany and more.

Delegates were welcomed at the Melbourne Aquarium on the Sunday Night’s Welcome Function sponsored by Incospec & Associates Australia. With a live jazz band playing in the background, delegates mingled around the aquarium’s Coral Attoll which is a floor to ceiling display of exotic tropical animals and beautiful coral gardens.

The official opening on the Monday morning was chaired by conference convenor Ian Godson and conference technical chair Nick Birbilis which included the starting of the Corrosion Clock by conference co-technical chair Bruce Hinton. Plenary speakers Tony Hughes of CSIRO and Mario Blasco of Dulux Protective Coatings commenced the conferences technical programme before concurrent sessions split the delegates into five separate streams for the duration of the day for 45 papers and the Coatings Technical Group Forum.

At the end of the first day, delegates then gathered into the exhibition hall for drinks and finger food while at the same time, the Young Corrosion Group (YCG) Event sponsored by the Galvanizers Association of Australia took place at the Tonic Bar. This event acknowledged the recipients of the various ACA Branch Conference Scholarships; Newcastle: David Sunjaya, NSW: Alan O’Connor, Blane McGuiness, Negin Sharifi & Philip Bird; Queensland: Don Macisaac, Nick Dodlo & Rana Everett; New Zealand: Raed El Sarraf.

YCG’s still networking at the end of the event, a strong YCG contingent moved onto a ‘best of Melbourne’ pub crawl.

Graham Sussex presented the PFT Lecture (inaugurated in 1971) on the Tuesday morning which is named in honour of Percival Faraday Thompson (1885-1951) who is recognised as Australasia’s pioneer in the science and technology of metallic corrosion and its mitigation. This year’s PFT Lecture was attended by Percival’s grandson and granddaughter who both reside in Melbourne. The PFT Lecture was followed by Bruce Ackland who presented his paper ‘Cathodic Protection – It Never Sleeps’ which was also published in the last issue of Corrosion & Materials.

Following morning tea in the exhibition hall (sponsored

by Mears Integrity Solutions) delegates had another 32 oral papers to see as well as forums from the Concrete Structures & Buildings, Cathodic Protection and Water & Water Treatment Technical Groups. During afternoon tea, the poster session was held with university students showcasing their research. A cash prize was awarded to the best posters this year and was received by Ruifeng Zhang of Monash University ($750), Muhammad Awais Javed of Swinburne University of Technology ($500) and Parama Chakraborty Banerjee of Monash University ($250).

Australia’s most prestigious ballroom, the Crown’s Palladium was the setting for the ACA Annual Dinner & Awards night which was again sponsored by Denso Australia. Australasian President Peter Dove entertained the crowd as MC and with the ACA Awards Convenor Les Boulton announced this year’s ACA award recipients (see page 33-35 for details). Following formalities and the Major sponsor:

main course, delegates young and old danced the night away to The Gary Eastwood Express which was backed up at times from Denso Australia’s very own David Towns.

Following little sleep, a strong number of delegates attended the Wednesday plenary presentations from Paul Natishan of the US Naval Research Laboratory and Geraint Williams of Swansea University, UK. By the time the morning tea break finished on Wednesday, delegates had sipped through over 1,000 Zinga branded sponsored coffee cups (which was more than during the international congress last year in Perth).

The final 22 papers and the Petroleum & Chemical Processing Industry Technical Group Forum closed off the last day of the conference before the Closing Session and Farewell Function.

A major thank you to Dulux Protective Coatings as major sponsors of the 2012 conference who were represented at the conference by Jevan Dickinson, Mario Blasco, Ross Boucher, Judy Knapp and other key personnel.

A further thank you to International Protective Coatings, Jotun, Peerless Industrial Systems and PPG Protective & Marine Coatings for their supporting sponsorships.

The ACA now looks forward to the 2013 conference in Brisbane on the 10-13 November at the Brisbane Convention & Exhibition Centre.

corrosion & prevention 2012 TECHNICAL REVIEW

corrosion & prevention

technical review I trust you all had a lovely Holiday period!! Whilst the celebrations are now behind us and the new year is already in effect, the technical impact of the C&P 2012 meeting still continues. It gives me great pleasure to pen a technical review for what was one of the largest and technically intense corrosion meetings ever to be held in Australia. In fact, the meeting was so comprehensive that a technical review is a task beyond a single editorial, so instead I will do my best to summarise.

From its inception, the C&P 2012 meeting in Melbourne was destined to be synonymous with the science of corrosion, given the role of Melbourne as a hub for corrosion research (CSIRO, DSTO and corrosion groups at all of Swinburne, RMIT, Deakin and Monash Universities), along with the major consulting activities synonymous with Melbourne. As the historical home of the ACA, there was also an enthusiasm from the Victorian Branch to cover the range of corrosion activity important to Australia.

As a result of the above, several concurrent streams were run in the technical program, covering lengthscales commencing at single atoms, up to thousands

p.32 CORROSION & MATERIALS

of kilometres of pipelines. Popular topics included infrastructure, coatings, modelling, defence, oil & gas, science and inhibitors. In order to bolster the technical streams and provide a critical global context, the C&P 2012 meeting introduced an ‘Invited Speaker’ initiative.

This allowed the technical convenors the ability to invite the key international authorities on specific topics to attend C&P2012, which not only provided for excellent presentations, but also for excellent discussions and question time. We are very grateful for the journey our invited speakers made, and the significant contribution they had to the meeting. Such speakers included Prof. Vicki Gelling (North Dakota), Prof. Dave Williams (Auckland), Prof. Llyod Hihara (Hawaii), Dr. Alan Turnbull (NPL), Dr. Joe Osborne (Boeing), Dr. Gareth Glass (CPT), Dr Dave Shifler (ONR), Prof. Scott Lillard (Akron).

In addition to the invited speakers, the topical plenary speakers also delivered timely and interesting presentations (Prof. Paul Natishan, Prof. Geraint Williams, Dr. Tony Hughes, Dr. Graham Sussex, Dr. Bruce Ackland) – which were well received and also illuminated some of the future challenges in our field.

In summary, the breadth of topics covered, and the farreaching implications (social, financial, environmental) of corrosion were showcased. It is evident that corrosion science, corrosion technology, and corrosion protection are all issues that are not only very important today, but will be increasingly important in a number of industries and fields. I would like to thank all of those who spent the time preparing excellent presentations (including the large cohort of students) and who contributed to the technical aspects of C&P2012. As I mentioned, a single summary cannot even begin to isolate the technical nuggets from what was an excellent C&P2012, so I will not even try. Instead, I urge you to attend C&P 2013, which will no doubt continue the delivery of a high level of technical content, and you can see the spectacle for yourself.

awards Each year a series of ACA Awards are announced and presented to successful recipients during the gala dinner at the annual ACA conference.

The ACA awards papers of outstanding quality presented at a conference, seminar or symposium held under the auspices of the ACA, or published in the ACA’s publication Corrosion & Materials. These papers are judged by the ACA Awards Committee comprised of Les Boulton, Bruce Hinton and Erwin Gamboa.

The ACA also recognises members for outstanding services to the Association through Life Membership and services to the industry through the Corrosion Medal.

AC Kennett Award The AC Kennett Award is awarded each year to the best paper presented under the auspices of the Association that deals with non-metallic corrosion. The recipient also receives a cheque for NZ$1,500.

Greg Moore, John Scheirs & Paul Vince for the paper ‘Deterioration of Flexible Polypropylene Reservoir Liners and Covers in Contact with Potable Water’ presented at the 18th International Corrosion Congress, Perth 2011.

SUMMARY: Flexible polymeric liners and covers have increasingly been used in water storages due to their ability to prevent evaporation, suppress loss of chlorine disinfectants and minimise the risk of water quality incidents. They also present an economic alternative to concrete storages with permanent roof structures.

Recently, there has been a series of premature failures of covers in Australia. The resultant reduction in asset life has a significant impact on the economic viability of the covers; not to mention the risk of water contamination.

This paper covers the process of failure investigation of such a cover including the specific testing required for these specialised covers. In particular, the phenomenon of flaking is described; observation of which is believed to be only the second such incident in the world. The role of operating conditions, including chlorination and

Best Papers In pursuit of attracting quality technical papers, the ACA annually awards two certificates of merit for papers either published in Corrosion & Materials or presented at the annual conference. The award will be made only where the standard of papers is of a level warranting recognition; one certificate is for the best review paper and the other is for the best research paper.

Marshall Fordham Best Research Award Igor Chaves & Robert Melchers for the paper ‘Long Term Marine Corrosion of Welds on Steel Piling’ presented at the 18th International Corrosion Congress, Perth 2011.

SUMMARY: Welds on mild and low alloy steels exposed to the marine environment are known to be prone to high levels of corrosion. Pitting usually is the critical form of attack. Quantification of the relative and absolute maximum pit depths that occur is important for predicting future and remaining structural life but longterm data is scarce. The present paper reports on a study of the statistical characterization of pit depths measures on longitudinally welded steel piling exposed for some 33 years in Newcastle harbour. The investigation is based on the hypotheses that the lack of homogeneity at the corrosion interface caused by differences in grain size, grain structure and the potential for pitting to occur preferentially along boundaries is responsible for the observed effects. The pit depth results obtained are compared with the results reported earlier for maximum pit depths measured on welded steel coupons exposed to similar Pacific Ocean 20oC seawaters for up to 3.5 years. It is shown that there is a reasonable degree of consistency between the two sets of results, adding confidence to the possibility of extrapolation of medium term data to the longer term.

pipeline performance. Some of the issues that need to be overcome to provide reproducible and accurate results are outlined, as well as suggesting methodologies to overcome these limitations.

Finally, the future of soil electrochemical testing is briefly discussed including current research work aimed at providing both improved laboratory test cells using both LPR and EIS techniques and developing robust in situ soil electrochemical test probes.

David Whitby Best Review Paper Award David Nicholas, Phillip Ferguson & Matthew Dafter for the paper ‘Electrochemical Determination of Corrosion Rates of Water Mains in Soils: A Review’ presented at the 18th International Corrosion Congress, Perth 2011.

SUMMARY: The use of electrochemical techniques, in particular linear polarisation resistance (LPR), to determine instantaneous corrosion rates of buried ferrous pipes in soils are reviewed from a historical basis. It is shown that whilst these techniques have been available for some time it is only since the 1990’s and beyond that attempts have been made to successfully correlate the instantaneously derived corrosion rates with the long-term performance of buried cast iron and steel pressure water and sewer mains.

The development of a commercial LPR test method as an essential step to predicting pipe performance is described and some of the difficulties and drawbacks found in providing reproducible test results outlined.

More recently, alternative soil corrosion rate test methods have been advocated and these are discussed and criticized from a corrosion engineering viewpoint as to their ability to provide accurate results capable of providing input into statistically based prediction of

Aaron Sudolz of Monash University for the paper ‘The Effect of Rare Earth Element Additions on the Corrosion Behaviour of Magnesium Alloy AZ91E’ presented at Corrosion & Prevention 2012.

SUMMARY: In the present communication the impact of precise rare earth (RE) elemental additions, such as Ce, La and Nd, on the corrosion of magnesium alloy AZ91 is explored. This investigation was undertaken in an attempt to assess whether the corrosion rate of AZ91 can be favourably altered as a result of engineering the rate of the anodic and cathodic reactions upon the alloy.

It was found that low levels of these RE additions are a means for imparting an improved corrosion resistance on AZ91 and this communication outlines the underlying mechanisms involved.

COATINGS GROUP MEMBER PROFILE

Eddy Batur Industrial Painting Q: In what year was your company established?

A: The company was first established on the 1st July 1982 at our original site in Hastings Victoria.

Q: How many employees did you employ when you first started the business?

A: We first started with 8 permanent Blaster/Applicators.

Q: How many do you currently employ?

A: Today we have 2 permanent office staff and 9 full time Blaster/Applicators and when the job requirement demands, we increase the work force as necessary.

Q: Do you operate from a number of locations in Australia?

A: Yes, we operate from the factory in Hastings and on specific work projects across Victoria.

Q: What is your core business? (e.g. blasting and painting, rubber lining, waterjetting, laminating, insulation, flooring etc.)

A: Our core business operates around Blasting and Application, Pipe lining and coating both internal and external.

Also, at times we have used our own rubber applications for clients.

p.46 CORROSION & MATERIALS

Q: What markets do you cover with your products or services? eg: oil & gas, marine, chemical process, general fabrication, tank lining, offshore etc.

A: Our work processes cater to all of the above and we have conducted spray applications for Non Skid and Rubber Spraying.

Q: Is the business yard based, site based or both?

A: Both, as stated earlier we operate from a complex in Hastings which incorporates a Blast Booth and a Paint Shop.

Q: What is your monthly capacity or tonnage that you can blast and prime?

A: 500 to 1000 tonnes monthly.

However, we cater to varying meterage depending on flat surfaces.

Q: Do you offer any specialty services outside your core business? (eg. primary yard based but will do site touch up etc.)

A: Yes, we are able to offer pipe blasting and coating down to 25mil (1”) internal with coatings holding consistent thicknesses throughout down to 100mil (4”). This includes pipes that reduce and enlarge throughout the length or have bends and angles in their design.

Q: What is the most satisfying project that you have completed in the past two years and why?

A: Ballast line piping where we completed the blasting and coating both internal and external. This project allowed us to develop, trial and prove a piece of equipment which has been designed and manufactured ‘in house’ to blast and coat to consistent standards throughout while the process may be viewed on CCTV.

PROJECT PROFILE

CityLink Gateway Red Restored Introduction Transurban’s CityLink Gateway is one of Melbourne’s most striking icons.

Designed by internationally renowned architects, Denton Corker Marshall, the Tullamarine Freeway south exit features DCM’s signature rectangular angled columns. One massive yellow column at the beginning of the Gateway bows deeply to thirty nine tall red columns opposite, each 30 metres high and leaning towards the freeway, cheerfully greeting both locals and tourists alike as they approach Melbourne from the Airport. Each red stick consists of a concrete base, with steel angles and a steel plate.

Originally fabricated in 1999 in the Latrobe Valley, the red “sticks” and yellow column had been repainted in the mid 2000’s, and were due for maintenance.

The red sticks were in reasonably good condition with only a few small, isolated patches of corrosion evident.

Although the previous polysiloxane coating had retained its gloss quite well, the colour had faded on the north and west faces, and isolated areas exhibited some delamination.

Nevertheless, Transurban’s priority was to use a coating system that protected the sticks and delivered long term colour durability.

p.48 CORROSION & MATERIALS

Colour Durability Challenge At original design stage, the Architects had selected and specified the richest, brightest red available in the 1990’s the (now obsolete) Master Palette Atlas, Cherry Red. Achieving this bright red colour would have required the blending of both organic and inorganic pigments, but organic pigments generally have low opacity and require multiple coats to cover adequately. Moreover, the brighter organic pigments derive their colour from complicated chemical structures with conjugated double bonds that are sensitive to UV rays, and readily break down on exposure to sunlight. Thus the harsh Australian sun and weather cycles faded the colour of a succession of coating system types, necessitating a repaint every few years to maintain the design integrity of this important city feature.

Formulation Work In order to maintain the City Link Gateway’s signature red sticks in a bright red colour as close as possible to that intended by the Architects, work began in the Dulux Innovation and Technology labs using a new, UV stable and unusually bright and clean red pigment, in a polyurethane formulation designed to achieve high film builds and excellent flow out using conventional brush and roller application. The pigment is an integral part of the base paint formula, rather

than being post-added as tinter to the finished product as often occurs.

Given the logistics of accessing, cleaning, preparing and painting thirty nine angled columns from cherry pickers, the challenge was to find a coat system that could provide complete coverage in two coats. The system ultimately chosen comprised a single coat each of Dulux Durebild STE surface tolerant epoxy and Dulux Weathermax HBR high build recoatable polyurethane in “CityLink Cherry Red”.

New Coating Evaluation Site samples of Durebild STE were applied over several areas of the Red Sticks, including both the polysiloxane coating and the exposed, aged polyurethane coatings and adhesion tests were carried out to ensure the system would perform.

A standard roller was sufficient to apply the “CityLink Cherry Red” Weathermax HBR topcoat in one single coat to cover the light grey Durebild STE completely.

Access Given the height of the sticks and their proximity to the freeway, cherry pickers were the most appropriate form of access. The platforms were generous enough to hold a painter or two, mixed paint material and rollers on extension poles and any other equipment the applicators required.

PROJECT PROFILE

Spray application was not considered, as the risk of overspray reaching nearby vehicles was unacceptably high. As both prep coat and topcoat were applied using roller, there was no risk of mist inhalation. Solvent vapour inhalation was not an issue either, as both products are relatively high solids and the atmospheric concentration was very low, particularly in such an open, breezy environment.

Surface Preparation Being an area of high airborne pollutants from heavy vehicular traffic, the CBD and nearby industries the surface of the Sticks had to be thoroughly cleaned using high pressure water jet. The pressure was adjusted so as to not tear off soundly adhering

coatings, but to completely remove all surface contaminants including firmly adhering dust, oily deposits, bird droppings, tree resins and loosely adhering coatings. Isolated rusted areas were power tool cleaned to remove rust.

Painting After the surface had dried, and before contamination could reoccur, bare metal areas were spot primed in Zincanode 402 (a zinc-rich epoxy primer) before a coat of Durebild STE in white was applied to the entire surface to enhance inter-coat adhesion. The Weathermax HBR in the bespoke Citylink Cherry Red special process colour was applied within the recoat window of the surface tolerant epoxy to ensure maximum bonding and protection.

All work was undertaken strictly according to Transurban’s specifications

by Mattioli Bros.

Conclusion Now that the project has been completed, travellers through the Citylink Gateway can again enjoy the vivid design.

The choice of high solids polyurethane technology in combination with a new UV stable pigment incorporated at milling stage will ensure a coating system that will resist fading for much longer than had been previously achieved.

PROJECT PROFILE

New Systems Open Opportunities for Cathodic Protection in Concrete Repair Cathodic protection (CP) offers the advantage of permanent repair that does not require the expensive break out of sound but chloride contaminated concrete. Current is passed between an anode and the reinforcement, the reinforcement becomes cathodic and corrosion is halted, even if there are high levels of chlorides at the bar.

Although recognised as providing the ultimate corrosion protection impressed current CP (ICCP) may, in some circumstances be expensive to design, install and maintain. Michael Moore of Road and Marine Services (RMS) has been trialling a range of sacrificial anode CP (SACP) systems that have the potential to provide low cost, low maintenance holding repairs.

If ICCP systems were all that was available Mr. Moore believes it would be difficult to provide the required maintenance in NSW bridges within budgetary constraints. Unfortunately there are reservations about sacrificial systems as historically zinc anodes have passivated and CP Standard criteria for potential decays have not been met.

Three new innovative systems available in Australia are changing how people perceive ICCP and SACP. Low pH, Chloride Based Activation Pastes for Sacrificial Zinc Anodes RMS have recently installed corrPRE’s ‘Zinc Layer Anode’ as a small-scale trial on a Bridge in NSW. Mr Moore noted “This is part of a wider assessment of SACP but the apparent advantage of corrPRE Zinc Layer Anode is the relatively simple installation”. Other advantages of corrPRE Anodes is that they offer a higher long term output due to the nature of the zinc activation medium and they can be easily replaced. They also have a long term track record in Europe of giving repairs that meet the potential decay criteria in the Australian CP Standard he added. Hence they can be used as true CP systems not requiring removal of sound but chloride contaminated concrete rather than just for cathodic prevention.

p.50 CORROSION & MATERIALS

Figure 1 : Zinc Layer Anode applied to bridge beam and columns prior to application of top coats.

The Zinc Layer Anode (ZLA) is a 250 micron thick, 250mm wide roll of zinc sheet. The protective sheet over the adhesive backing is peeled off and the zinc sheet pushed onto the concrete surface. The adhesive has a slightly acid pH and contains chlorides that keep the zinc active. The zinc chloride reaction products that form as the zinc is consumed in the protection process are soluble and move away from the zinc so it remains active.

Chlorides in the concrete are pushed away from the reinforcement and into the adhesive and are beneficial to the CP system. Removal of the chlorides and re-alkalisation at the bar follow the normal trend of CP providing for lower currents and longer life of the system.

The ZLA adhesive is water soluble so it is only used above the splash level and is coated with a water proof aesthetically pleasing coating.

RMS are also using the corrPRE Roll Anodes that comprise rolled up zinc sheet with a similar activation paste to the ZLA. They are inserted into drilled holes and capped with a mortar plug. RMS are using them in a system with remote anodes in the water to protect the lower tidal zone, ZLA in the atmospheric zone and Roll Anodes in between.

Ribbon Anodes Deployed in Inert Housing At Dalrymple Bay Coal Terminal (DBCT) 3.3 m long glass fibre trays containing ribbon anode and a contact felt were bolted across the tunnel at approximately 200mm centres. The system was designed as a standard ribbon anode system by Infracorr Consulting. ‘Cassette’ offered the installer, Freyssinet Australia the advantage of easier installation than the alternative of placing the anode in slots or shotcrete. For the client it offered simple inspection and maintenance but with a long life and low risk relative to ribbon anodes in cement where acid attack at the anode concrete interface has caused problem in the past.

Freyssinet’s repair manager Chris Mein told ACA that “Freyssinet found it easy to adopt Cassette as apart from the simplicity and speed of installation it offered us, it had been used successfully overseas and it has a 10 year track record and good credentials.”

According to Mr Mein installation of Cassette at DBCT went according to plan and proved as simple to install as they had expected. “The lead time for this project was short but the manufacturer was able to manufacture a special product

He went on “Cassette removes many of the obstacles of applying a ribbon anode and its ease of application and relatively low cost makes it very competitive. At the time of the DBCT project only Type S1 was available.

If Type D had been available then the spacing of Cassettes would have been doubled making it even more economic. We have recently tendered on a project using the Types D1, D2 and D3 for a significant saving relative to the shotcrete and mesh

system specified. The system is ideal in industrial applications such as tunnels, basements and under wharves and bridges where the cassettes on the surface are not an impediment. Where an obstacle free, aesthetically pleasing surface is required we are offering the Zebra conductive coating as another alternative to conventional ICCP”.

Conductive paints are not new to Australia and one system was applied in WA nearly 30 years ago as a trial.

It exceeded its design life of 20 years but no-one took on the system commercially. An improved system that uses a silicate based binder rather than the chlorinated rubber based binder on the system installed 30 years ago is now being offered in Australia. The silicate offers good bond to the concrete and enhanced conductivity.

UNIVERSITY PROFILE

Corrosion Research at Swinburne University of Technology Corrosion research at Swinburne University is largely applied in nature and is aimed at tackling industrybased problems. Researchers working on corrosion are based in a number of research centres within the university including the Industrial Research Institute Swinburne (IRIS), the Centre for Atom Optics and Ultrafast Spectroscopy (CAOUS), the Centre for Sustainable Infrastructure (CSI) and the Environment and Biotechnology Centre. A list of some of the corrosion related studies at Swinburne are provided below.

Research Projects: 1. Corrosivity of Australian seawaters and microbiologically influenced corrosion Funded by the Defence Materials Technology Centre (DMTC), researchers at Swinburne University in collaboration with ASC Pty Ltd are undertaking a detailed testing program to measure seawater parameters at several sites relevant to a range of maritime infrastructure. Work is being carried out to identify local characteristics, and seasonal effects, related to general corrosion and microbiologically influenced corrosion (MIC) from target locations, and to identify the presence of MIC-related microorganisms.

The projects aim is to provide fundamental information to develop improved maintenance procedures and understanding of the parameters driving corrosion, allowing the future development of sensor technologies and mitigation techniques.

2. Paint degradation sensing The precursor to corrosion of many metallic materials is the degradation of a protective paint scheme, thus the ability to have a monitoring capability of this degradation is of great benefit to corrosion prognostics. Work is underway to develop an optical fibre based sensor using fluorescent coatings which can provide an indication of paint degradation. Some of the potential advantages of an optical fibre based sensor include light weight, small size, the potential for monitoring at multiple sites and the possibility of terminating the sensor at convenient maintenance access points. The sensor is initially being designed for aircraft applications to provide a capability that allows the rate of internal paint degradation to be monitored which will reduce the high maintenance burden of unnecessary scheduled deeper maintenance. It will also permit prediction of the condition of internal bays so that maintenance forward-planning and repair logistics can be achieved more efficiently. This project is funded by the DMTC and is a collaboration between Swinburne University, BAE Systems Australia, the Defence Science Technology Organisation (DSTO) and Queensland University of Technology.

Contact: Dr Scott Wade (swade@swin.edu.au)

3. Microbiologically Influenced Corrosion Microorganisms such as bacteria, algae and fungi can influence, directly or indirectly, the degradation rates of a wide variety of materials including metals. The most commonly known result of microbiologically influenced corrosion (MIC) is the rapid localised pitting of steels for example in piping, storage tanks and maritime infrastructure. Research interest related to MIC at Swinburne University includes: Investigation of the effect of substrate properties (e.g. roughness and metallurgical structure) on the attachment of bacteria and the subsequent development of biofilms Development of procedures to identify MIC and the bacteria involved in MIC MIC in drinking water pipes using metabolomics platforms (with CSIRO) Research in MIC requires a multidisciplinary approach to understand the full complexity of the processes taking place. At Swinburne we have brought together a team including chemists, metallurgists, physical scientists and microbiologists to collaborate on MIC-related problems.

UNIVERSITY PROFILE

4. Development and testing of corrosion sensors While working at Monash University on a CRC-IEAM project with DSTO, Vinsi Partners Consulting Engineers and the University of South Australia, Dr. Wade helped to develop a corrosion sensing system based on the electrical resistance method. Sensors and logging units were installed at a range of research and industrial test sites around Australia. Dr. Wade is assisting the on-going development and testing of the sensors with the aforementioned project partners and the Queensland University of Technology as part of a further CRC-IEAM funded project.

5. Corrosion of high temperature alloys In collaboration with the DMTC this project revolves around protecting materials against high temperature oxidation. The aim temperature is in the order of 3000 ºC for hypersonic applications. The coating design incorporates oxide ceramics that are based on alumina and zirconia ceramic alloys. The challenge has been in depositing these ceramic layers onto materials that require minimal surface preparation via thermal spray technologies. This project has investigated additive manufacturing techniques that incorporate solgel impregnation and laser glazing methods so that a thick coating of about 1 mm can be functional within an aggressive oxygen-bearing and high temperature environment.

9. Corrosion protection of Magnesium alloys in biological environments Medical implants made with magnesium and some of its alloys are receiving increasing attention because they are completely degradable in the human body after the implant has completed its function. However, the high corrosion rate in a biological environment, which produces hydrogen gas, significantly limits its application. Researchers at Swinburne University led by Prof. Cuie Wen are developing novel coating technologies to protect Mg alloys from rapid corrosion. By using methods such as anodization or deposition, a thin protective layer could be coated on the surface of Mg alloy. Funded by AustraliaIndia Strategic Research Fund, the project aims to develop coatings to tailor the corrosion rate of Mg and its alloys for biodegradable implant purpose.

8. Laser processing of NickelAluminium Bronze for improved corrosion performance Nickel-Aluminium Bronze is used extensively in marine applications and as such it suffers from corrosion.

The corrosion can be linked to the precipitates in the microstructure. Laser processing has been investigated to change the microstructure and improve the corrosion performance. By heating close to the melting point with a long enough dwell time the κIII precipitate of the as cast Nickel-Aluminium Bronze microstructure dissolve, which improves electro-chemical corrosion characteristics as well as cavitation erosion characteristics. Both of these forms of corrosion are potential problems during the service life of propellers and valves made from Nickel-Aluminium Bronze. The project is funded by the DMTC and is a joint effort between Swinburne University of Technology, ANSTO, DSTO, RMIT and The University of Melbourne.

6. Polymer Barrier Coatings for Ambient Temperature Applications This work has been sponsored by two Swinburne Post Graduate Awards.

Deposition of polymers such as ethyl methyl acrylic acid and polypropylene have enabled the creation of thick (> 1 mm) coatings that can be employed for corrosion protection; for example of infrastructure such as pipelines, structures and domestic buildings.

This study has been fundamental in nature where “splats”, the essential building block of all thermal spray deposits, have been created under controlled conditions. A taxonomy for these individual features has been established and the way in which these are transformed into integrated coatings has been developed. This theory has been very useful in presenting a phenomenological picture of coating growth and how the thermal spray parameters can be adjusted to fashion specific coatings for different environments.

7. Corrosion of Magnesium and Assemblies Studies of the corrosion of magnesium alloys have been undertaken for a number of applications as part of collaborations with industry and other research organisations. Work has been carried out together with CSIRO, Monash University, Central Queensland University, Magontec (a supplier of high purity magnesium alloys), Henrob (UK) Pty Ltd, Henkel Australia Pty Ltd and DSTO with funding from various sources including the CAST CRC. One example of recent research is work undertaken to investigate the influence of laser treatment and silane coating on the corrosion of ZE41 alloy. Other ongoing research is related to joining activities for the automotive industry.

This work deals with the development and study of the influence of rivet coatings and Mg surface preparation on the general and galvanic corrosion performance of self-pierce riveted assemblies with and without adhesive.
