CHAIRMAN'S MESSAGE

shoes you have left behind and carry on leading the Association into the future delivering and building on our ACA strategic plan.

For those who don’t know me, I am a couple years shy of a half century and I have a young daughter named Hannah. Professionally, I am a ‘solvent sniffer’ from Launceston, Tasmania and have been involved with the ACA for nearly 25 years, being introduced by my employer way back when I first got involved in protective coatings.

Dean Wall Chairman Greetings everyone, this is my first message as the newly appointed Chairman of the ACA Board and I would first like to thank our outgoing Chairman Paul Vince for making such a valuable contribution to our Association during his 7 years on the ACA Board, with the last 4 years as Chairman.

I am currently employed by Jotun Australia as the Sales Manager for Marine & Protective Coatings responsible for Tasmania, Northern Territory and New Zealand. I have served many a role within the ACA both at local Branch and national levels. I was National President in 2006, and have had two stints on the ACA Board as Membership Director and Events Director. Most recently I have been responsible for leading the ACA Foundation, serving on the current Board and as the current Conference Committee Chairman.

During this time Paul has lead our Association through significant change and shown strong leadership and support in conjunction with fellow Board members, our ACA Centre staff and the membership. He has helped foster our ongoing relationships with our Training Partners in NACE International, SSPC and ACRA and represented the membership both in Australasia and overseas.

My time as ACA Foundation Chairman saw significant announcements concerning scholarship funding opportunities and the Young Corrosion Future Leaders Forum. In total, over $100,000 has been awarded to fund a range of scholarships which will benefit all sectors of the industry. I wish to also thank the ACA departing Chairman and fellow Board members for their support of the ACA Foundation during this time, along with all ACA Foundation Donors.

Paul, on behalf of the Board and all members, we appreciate your direction and friendship during many a Board meeting and I hope I can fill the big

The recent ACA Corrosion & Prevention 2015 conference in Adelaide was a great success and was well supported by over 500 attendees.

Raise your company's profile

During Corrosion & Prevention 2015 our newly formed Council met and was well lead by the 2015 Australasian President Mohammad Ali. I can also report that Peter Dove and Kingsley Brown were re-elected and that Brad Dockrill is the newly elected member to the ACA Board also. Congratulations to all elected Board members and to all those who nominated. I am also very pleased to announce that John Duncan of New Zealand has been elected Australasian President for 2016.

Congratulations to John and the ACA Board looks forward to working with you. I can also announce that Erwin Gamboa was appointed as the ACA Junior Vice President The ACA Board also wishes to acknowledge the fine efforts of ACA Executive Officer Wesley Fawaz and voted to extend his contract for another two year term in recognition of his great efforts over the last couple of years in managing the operations of the ACA. In closing my first column, I would like to say thanks firstly to my employer Jotun Australia for their ongoing support of my involvement in the ACA. On behalf of the ACA Board to all the ACA staff and volunteers for all their efforts during yet another demanding year - we have come out on top and delivered yet another wonderful year of events for our members. I look forward to your ongoing efforts in supporting the development of our future ACA in 2016.

Yours in Corrosion and best wishes for the Festive Season.

EXECUTIVE OFFICER’S MESSAGE

him in Adelaide to discuss further. I will keep you posted as this evolves.

A summary of Corrosion & Prevention 2015 along with a selection of photos will be published in the first issue of ‘Corrosion & Materials’ in 2016, but for now, congratulations to those who received ACA awards including the new ACA life members in Peter Hart, Graham Sussex, John Grapiglia and Brian Hickinbottom; in recognition of their support and dedication to the ACA over many many years.

Wesley Fawaz Executive Officer

Building on its long term relationship, the ACA now has an expanded partnership with NACE International with two major announcements during Corrosion & Prevention 2015 in Adelaide.

1. A new 5 year agreement will see ACA bring NACE’s Cathodic Protection and Pipeline courses to Australia, New Zealand, Thailand and Vietnam in addition to the NACE Coating Inspection Courses.

These courses will be offered in 2016, and the ACA is now coordinating the operational and logistical aspects of this new agreement and further details will be announced accordingly.

2. A new 3 year agreement will see the ACA concrete repair course offered

by NACE International in the USA, Canada and the UAE.

The ACA Board met in November and a summary of this meeting will have been published in ‘Corrosion Matters’. One of the key decisions made by the Board during this meeting was to publish ‘Corrosion & Materials’ quarterly starting in 2016 instead of bi-monthly due to the increasing cost of printing and postage where many resource limited Associations have moved to electronic only publications. This decision will also free up staff resources to continue to build on raising the profile of the ACA and the corrosion mitigation industry through its public relations efforts. In the first three quarters of 2015, the ACA has coordinated 92 articles published in over 50 various media outlets to the advertising value of over $220,000.

As the Executive Officer of the ACA, the key message I continue to hear is the importance of ACA and our ability to connect our members with their peers through networking opportunities at events. I am delighted to report that in 2015 the ACA have delivered the following results to contribute to this outcome by:

elcoming over 350 people into W our membership community and surpassing over 2200 members in September this year Conducting 41 training courses for over 600 students Connecting over 1,000 members on LinkedIn and over 400 on Facebook Conducting over 70 Branch and YCG events Hosting our annual conference and exhibition that attracted over 500 delegates from Australia, New Zealand and around the world Conducting 11 one day technical seminars attracting over 500 delegates Hosting our first online webinar in October this year I thank you for your continued support and look forward to working with you as we grow the organisation throughout 2016 and beyond.

Finally to Paul Vince, thank you again for your support over the years and I hope you are sitting back relaxing reading this issue of ‘Corrosion & Materials’ with that well deserved bottle of red wine.

Merry Christmas to everyone and a Happy New Year. See you all in 2016.

Wesley Fawaz Executive Officer wesley.fawaz@corrosion.com.au

The first course will be scheduled along with the NACE ‘Concrete Service Life Extension’ Conference in May 2016 in Orlando, USA. Along with the ACA Chairman, I will continue to meet face to face with the leaders of NACE at least annually to continue exploring future opportunities for collaboration to benefit the members of each organisation and the corrosion industry.

Also during Corrosion & Prevention 2015, South Australian Senator Nick Xenophon who opened the conference, announced his interest and commitment to raising the profile of the cost of corrosion within the federal government and invited me to visit

ACA Holds its First Webinar The ACA hosted its first webinar on Wednesday 28 October discussing Advanced Materials in Desalination Plants. David Parravicini from Suez Environment (formally Degremont) shared his experiences in working at the Perth Seawater Desalination Plant.

David set the scene by explaining how desalination plants often operate in harsh conditions, with a majority of large scale plants operating in coastal environments. David then went on and outlined how this, coupled with the large amounts of seawater and brine processed by these facilities, means a high standard of materials are selected to give optimum life to the asset.

Materials range from composites such as; HDPE and GRP piping, concrete,

high alloy steels and even titanium.

This presentation gave attendees an insight into some of the corrosion mechanisms specific to seawater desalination, failures encountered and some of the strategies used to prolong asset life.

Manager, at the ACA at bpejkovic@ corrosion.com.au, or you can call +61 3 9890 4833.

The ACA would like to thank David for his input and time in presenting our first webinar and those who participated. The ACA is committed to running further corrosion based webinars in the future and is seeking suggestions on topics that you Members are interested in.

Any suggestions or questions about future ACA webinars can be emailed to Brendan Pejkovic Technical Services

New Olympus MD sets focus on customers “It is no longer enough to say we have the best product specifications and highest performance,” Bowe said.

James Bowe.

The recently appointed Managing Director of Olympus Australia and New Zealand, James Bowe, has set his sights on making the company a leading force in delivering value above and beyond its products.

“Customer service, on-site support, education, training, preventative maintenance and communication are key and it’s my goal to make Olympus the market leader in these areas.”

With a 19 year history at Olympus Australia and New Zealand, Bowe has been instrumental in transforming the company from a locally run distributor to a direct-to-market subsidiary of the international Olympus Corporation.

There are now more than 330

employees and a heavy investment in local infrastructure—with offices in Melbourne, Brisbane, Adelaide, Perth, Auckland, Christchurch and Wellington. Each office is staffed by teams of sales, service and support personnel ready to fulfil Bowe’s vision.

Olympus has achieved double-digit annual growth in the region over the past five years. According to Bowe, relationships with customers and the benefits which Olympus adds to their businesses are the biggest drivers of this success. He will continue to invest in these relationships during his time as Managing Director.

preparation baths was detailed and the grand finale was witnessing a batch of steel being dipped in the zinc bath.

Industrial Galvanizers - Aaron Harland (State Manager) and Matthew Harris (Site Supervisor) conducted the tour which was split into two groups.

The tour started in the yard with a very informative explanation of the design considerations and fabrication techniques to ensure the best outcome when using hot dipped galvanizing as the primary protection for steel.

They then entered the production area where the functionality of the

McElligotts’ - Karlo Poslon (Operations Manager) lead the tour through the production facility. The site has handled some massive structural items including wind farm towers and the Melbourne Star observation wheel.

Karlo showed us the shot blasting and recovery system and explained that the facility has thermal panelling that allowed temperature control to enable year round use without problems.

Karlo explained the various paint

systems in use and how these can be complimentary to the galvanizing process to extend durability (or when colour is a requirement).

An active Q&A session at each site was indicative of the interest. It was a truly great day and the refreshments that followed were enjoyed by all as they socialised in the late afternoon.

ACA Tasmania wishes to sincerely thank the management and staff of Industrial Galvanizers and McElligotts.

BRISTLE BLASTER ® For more than 25 years MONTI has been developing its own technology and is today among the world pioneers in surface preparation.

The patented Bristle Blaster® technology helps you to prepare the perfect surface and impress with: Surface cleanliness of SSPC 10 / NACE No. 2 / Sa 2½ to Sa 3 Anchor profile up to 120 µm ( RZ ) / 4.72 mils Removes corrosion, mill scale, and coatings No heat generation on the surface Lightweight and ergonomic design ATEX approval for use in zone 1 Contact us for more on our passion for surface preparation. www.bristleblaster.com.au p.22 CORROSION & MATERIALS

II 2G c IIA T4 X

ADVERTORIAL

Bristle Blaster® - Patented technology for surface preparation: The hand-held power tool drives the special polyamide Bristle Blaster® belt. The U-shaped anchored bristles are ground and angled to precise specifications. While the belt rotates, each wire bristle is stretched over the accelerator bar, causing them to strike the surface with about four times higher kinetic energy. As well as the removal of corrosion or coatings, the impact of the wires results in craterlike indentations on the surface. Even resistant coatings and mill scale, which are difficult to remove with abrasive tools, can be effectively and efficiently removed. Due to the special designed belts, the bristle tips retract immediately after the impact, resulting in a rough surface that is characterized by a variety of micro-craters. The emerging surface cleanliness, the roughness and the tensile strength values are comparable to a surface prepared by grit blasting. In addition, tests performed and published

by Marquette University in Milwaukee USA showed that Bristle Blasting leads to a material compression along the prepared surface, which in turn increases

the surface's resistance to cracking, fatigue and stress corrosion.

The resulting surface roughness is dependent on the nature and hardness of the material being prepared.

Surface profiles of up to 120 microns (Rz), correct use assumed, can be achieved. The bristle tips strike the surface vertically and "knock off" rust or coatings. Virtually no substrate material is removed. Since no frictional heat is generated (like with grinding tools), there is no heat generation on the surface. In contrast to grinding methods, there is no rubbing of rust particles or smearing of coating into the surface, due to the fact that the bristle tips individually impact and rebound from the surface.

Application Bristle Blasting is used for the spot repair of rusted and damaged areas on steel structures of any kind. The convenience of the 1.2 kilogram heavy drive unit, Bristle Blaster® Pneumatic, and the fact that complex equipment is

unnecessary and no waste products need be collected and disposed of, makes Bristle Blasting the preferred method for professional surface preparation in industries such as bridges, wind turbines, shipbuilding, offshore, petrochemical, pipeline and plant construction, port facilities, as well as power plants.

The Bristle Blaster® Pneumatic can also be used for work in Zone 1 (a potentially explosive environment), for example oil & gas platforms and petrochemical facilities. The unit is ATEX approved for use in Zone 1 with flammable gases, vapors and mists (category 2 devices according to ATEX 94/9 / EC), as per Ex II 2G c IIA T4 X.

Six Decades of Corrosion Technology Innovation From the earliest days of the Australasian Corrosion Association, it was well known that structures and materials deteriorate (corrode) over time. It was also recognised that new technologies and new materials would help minimise the impact and cost of corrosion as well as present new challenges that corrosionists, engineers and scientists would face.

“The technological developments of the last 50 years have been remarkable, and have probably equalled those of the whole previous history of man on earth–a hundred thousand or more years of effort–yet there is reason to believe that it will not take us anywhere near another 50 years to make such progress again. We are accelerating geometrically not arithmetically.” These were prophetic words spoken by Milton Speedie at the Association's annual conference in 1958.

“All these developments will bring their difficulties. There will be many new corrosion environments and a large variety of new problems can be expected. But there will also be new knowledge and new protective materials

p.28 CORROSION & MATERIALS

There are many members of the ACA who have witnessed these changes and the overall acceptance of technological changes during the latter part of the 20th Century.

technologist or technician has a much greater toolbox of equipment and knowledge to be able to do this today,” said Greg Moore, ACA Life Member, “It is a continuing challenge but ongoing improvements and enhancements will always help in this daunting exercise.”

Warren Green, Director and Corrosion Engineer at engineering consultancy, Vinsi Partners, said “We have more options today in how we maintain and protect structures. We have gained a greater understanding of these technologies and a willingness to implement them.”

“In addition to these new technologies however, we will also witness the continuing growth and usage of high-tech materials, particularly new superalloys, composites and metal matrix materials,” said Les Boulton, Principal Consultant with Les Boulton & Associates Ltd in New Zealand.

“We may only be able to control corrosion but the corrosion engineer,

CELEBRATING 60 YEARS • 1955–2015

more and more infrastructure is built, so too the actual monetary cost increases.

One of the most researched areas of corrosion technology has been cathodic protection (CP). Sir Humphry Davy first demonstrated the principles of CP back in the first half of the 19th Century and the process was mainly implemented to protect steel structures either in the ground or in water. It’s application to steel reinforced concrete—one of the most widely used construction materials around the world—did not take place until the 1950s when it was applied to buried pre-stressed concrete pipelines.

Concrete can degrade over time due to the embedded steel corroding and causing the concrete to crack and “spall”. While above ground applications of CP for concrete were trialled in the late 1950s, but it was not until the last two decades of the 20th Century that it had widespread use for concrete repair and proactive protection.

According to Green there have been many advances in electrochemical treatments. “With the latest IT

technology we can now remotely monitor the condition of a structure and control the application of the CP.”

Another area of concentrated research has been in development of new protective coatings for structures.

The cost of monitoring remote structures has been reduced over time. “Remote monitoring of multiple Transformer Rectifier (TR) units on steel pipelines became available and this allowed a reduction in the frequency of when technicians physically went to each TR unit to check its operation,” Moore added.

Early coal tar epoxies (CTE) and lead or chromate pigmented coatings showed that they provided good protection to structures. However, they also had the unfortunate side effect of being toxic to the environment and their use was phased out. This circumstance prompted the development of other coating types such as polyurethane, polyurea, polysiloxane and other epoxies which are now widely specified and used.

Another major change has been in the anodes used in CP. “Anodes changed from large and heavy high silicon cast iron anodes to Platinized Titanium and MMO anodes which were not only smaller and lighter but also provided a much longer working life,” said Moore.

“There are now anodes available in different materials and shapes. One form is a mesh that wraps around a structure, while others are ribbons or rods,” Green said. “You can even have a conductive coating painted over the whole structure that acts as a secondary impressed current anode.”

One of the most common types of coating have been zinc-based which continue to be widely used. Early inorganic zinc-silicate coatings were heat cured but these have been phased out and replaced by waterborne or solvent borne variants.

Commercial galvanizing of sheet and roll formed steel originally used a straight zinc coating, but in the '80s, a zinc-aluminium alloy was introduced which gave much

CELEBRATING 60 YEARS • 1955–2015

improved performance, particularly in marine environments. Enhancements have continued to be made in galvanizing techniques with the recent introduction of zinc-aluminiummagnesium alloy coatings.

Coatings were the workhorse of corrosion prevention in the 1970s and '80s and there are still many areas where they are required. Moore added “In the last 15 - 20 years there has been a gradual change in the use of corrosion resistant materials that do not require coating.”

These are just cursory reviews of some of the corrosion technologies that have been developed. There will continue to be technological advances during the next 50 years as well, but it is difficult to predict the form these will take. “We will all need to become more comfortable with newer technologies such as on-line corrosion monitoring; fast information retrieval through computer databases; expert systems; in situ remnant life assessment procedures; stress analysis techniques and other new technology that only a few years ago was restricted to research laboratories,“ Boulton stated.

Corrosion will only be beaten by the continued coordinated efforts of industry and academia working together to study the causes and remedies of all forms of corrosion, in addition to educating industry and the public.

“Environmental pressures will drive corrosion scientists and engineers to develop new techniques for corrosion control, and to accelerate the implementation of well-established technology,” concluded Boulton.

Since its foundation, the ACA has also provided a link for corrosion workers in Australia and New Zealand to their counterparts around the world and continues to be, a hub for discourse and discussion on all aspects of corrosion and its impact.

“Creating and maintaining an awareness of corrosion and its consequences has always been a core value of the ACA,” Moore stated.

NEW PRODUCTS SHOWCASE

New Emerson Wireless-Based Corrosion Monitoring System Emerson Process Management has launched an innovative new corrosion monitoring system for refineries. The Roxar Corrosion Monitoring system, consisting of wireless-based probes, will provide refineries with flexible, responsive, integrated and highly accurate corrosion monitoring.

Combined with the Emerson’s nonintrusive Field Signature Method (FSM) technology, a non-intrusive system for monitoring internal corrosion at the pipewall, refinery operators will be able to access more comprehensive corrosion information and corrosion rates, leading to improved operator insight and control over assets.

The new system will ensure optimal production processes and reduce refinery downtime with only the necessary amount of corrosion inhibitors being injected to meet environmental requirements.

The wireless-based corrosion monitoring solution also comes

with fast response times, continuous measurements and installation in the plant’s most critical and often inaccessible sections. The system provides crucial information to risk-based inspections with other wireless benefits including reduced installation costs and improved data management.

The system will also help identify and track opportunity/high TAN crudes and their corrosive elements.

Such crudes are less expensive but more corrosive than others with the new system enabling the maximum amount of such crudes to be blended into the mix without increasing corrosion risk. An increase in opportunity crudes from 1.5 percent to 3.5 percent in a refinery with a capacity of 300,000 barrels/day can result in savings of $8.6 million dollars per year based on a 4-dollar price difference.

CorrosionX Corrosion Inhibitor and Lubricant Local marine equipment supplier, Southern Seas Marine, is now stocking the CorrosionX corrosion inhibitor, lubricant and penetrant designed for use on sensitive circuits and electronic connections.

CorrosionX is safe for use on all electrical and electronic connections, switches, circuit boards and motors such as found on anchor winches, bow thrusters, lights, switch boards, batteries, pumps, refrigeration units and electronics.

It works by leaving an ultra-thin dielectric coating that drives out moisture and existing corrosion, cleans contact points and improves connectivity without interfering with the circuitry.

As a lubricate, CorrosionX will repel water and, because of its polar bonding technique, will not wash off.

Uses include throttle cables, steering mechanisms, seat swivels, locks, winches, hinges, windlasses or any metal part needing lubrication. It is ideal for fishing reels and guns.

As a corrosion-inhibitor, CorrosionX works on all metals such as stainless steel, steel, bronze and aluminium, and does not harm rubber or plastic.

It provides protection for the motor and gearbox when a boat is not being used for periods of time.

For protection of metal under water, the makers recommend using MaxWax, a wax with CorrosionX. On corroded or seized bolts, nuts, rigging screws and fittings, CorrosionX can also be applied to penetrate and un-seize quickly.

COATINGS GROUP MEMBER PROFILE

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

A: As part of the scope on a fabric maintenance project offshore, the client requested blasting and coating underneath the helideck on various corroded locations throughout the surface. To erect a scaffold would require a significant amount of heavy scaffolding and manpower. The platform’s storage capacity and space was very limited which provided an additional challenge.

IMS suggested installing tension nets in conjunction with rope access systems in place that would provide safe and easy access to all corroded areas that required attention. All the nets, wires and rope access equipment weighed approximately 450kg and were installed in 3 days with 4 technicians.

The surface preparation and coating was completed in 5 days and the

dismantling of the nets in 2 working days with 3 technicians.

The whole job was delivered in safe and efficient manner.

Q: What positive advice can you pass on to the Coatings Group from that satisfying project or job?

A: Sometimes the common methods of access are not always the best and most cost effective. Using this approach with rope access methods (tension nets) on our Client’s project gave IMS the opportunity to complete the tasks safe, efficient and minimising budget cost for the client.

Q: Do you have an internal training scheme or do you outsource training for your employees?

STOPAQ, IRATA Rope Access, BOSIET, Confined Space Rescue, Breathing Apparatus and First Aid are the standard certs but we are always adapting and improving our training skills to better meet our clients requirements, example the net installation training as mentioned above. Also as company policy we provide constant on-job training for our employees.

UNIVERSITY PROFILE

Corrosion Research at Swinburne University of Technology Corrosion research at Swinburne University is largely applied in nature, aimed at tackling industry-based problems. Projects underway cover the range from studies of fundamental science/engineering through to field trials of prototype systems. Two of the main themes of research are the study of the influence of microorganisms on corrosion and the development of new materials and coatings with improved corrosion resistance. A description of some of the corrosion related studies at Swinburne are provided below.

Research Projects: 1. Microbiologically Influenced Corrosion (MIC) & Testing Procedures Microbiologically Influenced Corrosion (MIC) refers to the ability of microorganisms to influence the corrosion of materials. Historically laboratory tests for MIC have been performed in specialised liquid media using test conditions which were designed for the growth of microorganisms. These conditions however do not replicate the environments in which MIC occurs in the real world and so there needs to be caution about the over interpretation of the results of such tests. At Swinburne we have been undertaking research into how laboratory-based test conditions can affect the test outcome. We have shown for example that in a test undertaken using the same strain of bacteria that corrosion can either be prevented or amplified depending upon the choice of test media. The overall goal of this work is to provide guidance to MIC practitioners on appropriate testing methods.

p.40  CORROSION & MATERIALS

2. Flow Effects on MIC To date the majority of MIC studies have been performed in static systems, i.e. with no fluid flow. MIC however is a major problem for many structures, such as pipeline systems and heat exchangers, where fluid movement is typical. While there have been some studies of MIC in dynamic systems, they have in general consisted of relatively simplistic testing arrangements. The initial attachment of bacteria and corrosion can be significantly affected by local flow conditions and therefore further work is required to better understand the role of the dynamic component in these processes. This project is studying the contribution of fluid dynamics to the initial bacterial attachment and subsequent MIC with a focus on copper piping.

Contacts: Dr Scott Wade (swade@swin.edu.au) or Dr. Justin Leontini (jleontini@swin.edu.au) 3. Microbial Ecology and MIC The majority of environments in which MIC takes place consist of a diverse range of microorganisms and environmental factors. The composition of these microbial communities changes with location and time.

Individual microorganisms respond to surrounding habitats via their specific metabolisms and interactions with each other including cell-tocell communication via signalling molecules. Microbial attachment to materials leads to a complex microbial ecosystem developing and then individual microbial metabolites (e.g. acids, electrons) are hypothesised to influence metal corrosion. The specific details of these microbial communities and their processes can affect the degradation of materials. Traditional microbial methods include isolation of prokaryotes to pure culture in the laboratory followed by the use of particular isolates in simulation studies. However, since less than 1% of microbial species can be isolated to pure culture, use of these pure cultures for MIC studies should be augmented by modern molecular biological procedures. The aim of this project is to study the composition and evolution of microbial communities in relation to MIC. This will include the application of both culture-dependent and

advanced culture-independent methods including third generation DNA sequencing for population structural and functional analyses.

Figure 2: Microbes isolated from a marine sediment sample.

4. Accelerated Low Water Corrosion (ALWC) Accelerated low water corrosion is an aggressive form of localised corrosion that predominantly occurs at the low water level of marine structures and has been shown to be a form of MIC. While the presence of an orange bloom is commonly associated with ALWC, this observation alone does not confirm that ALWC is present. The verification of the involvement of microorganisms in the corrosion observed at suspected ALWC sites is critical as any future development or work undertaken to mitigate/remediate ALWC problems requires an understanding of the cause and severity of the issue. Work at Swinburne has included field and laboratory investigations in relation to developing test procedures for the definitive verification of ALWC. Contact: Dr Scott Wade (swade@swin.edu.au)

5. Advanced Surface Engineered Coatings for Marine Hydraulic Components Swinburne is leading a multidisciplinary team from the manufacturing and defence industry to investigate the use of thermal sprayed coatings for hydraulic components used in the highly corrosive and biofouling-prone maritime environment. The coating technology used, known as high velocity oxygen fuel spray (HVOF) produces dense, low porosity coatings that have significant advantages over other current coating methods (e.g. electroplated hard chrome). Hydraulic components are used in a wide range of critical functions on maritime vessels and failure can have significant impact the vessel’s ability to carry out required tasks. This collaborative research is funded by the Defence Materials Technology Centre (DMTC) and draws upon local and international expertise from MacTaggart Scott Australia, United Surface Technology Ltd, the Defence Science and Technology Group and Swinburne University.

6. Corrosion Properties of High Entropy Alloys High Entropy Alloys (HEAs) are a new class of alloys with multi-principle elements mixed in an equi-atomic ratio resulting in simple solid solutions. HEAs are known for their high temperature microstructural stability, enhanced oxidation, wear and also corrosion resistance. Apart from bulk material consolidation methods such as casting and sintering, Swinburne University has been successful in depositing HEAs as surface coatings. Swinburne is working together with the Indian Institute of Technology Madras, to develop new alloy compositions with interest in the distribution of corrosionresistant elements (such as Cr) and understanding the galvanic corrosion properties of these materials.

Contacts: Dr Andrew Ang (aang@swin.edu.au) or Prof. Chris Berndt (cberndt@swin.edu.au) 7. Corrosion of High Temperature Alloys In collaboration with the DMTC this project revolves around protecting materials against high temperature oxidation under extremes of 3000°C 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.

Contact: Prof. Chris Berndt (cberndt@swin.edu.au) 8. Polymer Barrier Coatings for Ambient Temperature Applications Deposition of polymers such as ethyl methyl acrylic acid (EMMA) 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.

Corrosion of Steel Fibre Reinforced Mortars Reinforced concrete is a common structural material used in marine applications, such as docks and wharves. However in this environment it is prone to costly failure, due for example, to corrosion of the steel rebar. In some applications steel fibre reinforced concretes have shown significant advantages over the conventional steel rebar system, e.g. improved resistance to cracking and crack propagation. Another hot topic of concrete research is the study of concrete composition with aims such as improving mechanical properties and reducing environmental impact. The objective of this project is to compare and contrast various types of steel fibre reinforced mortar in a marine environment. Samples of traditional, blended and geopolymer mortar with steel fibre reinforcement are being tested to look at the corrosion of fibres, any changes in bonding and matrix degradation. This information can be used to predict the service life of components made with the various grades of mortars/ concretes.

PROJECT PROFILE

Removal of Underground Earthing Facilitates Increased Corrosion Protection to Pipelines The pipeline industry is very collaborative in terms of cathodic protection, as everyone’s protection systems can affect each other’s assets detrimentally and end up inadvertently causing corrosion. Therefore, when a water authority wanted to increase the current output of their protection system, there was an increased risk of interfering with other asset owners in the area, so they contacted the gas authority for that area. There had already been issues with interference with the original commissioning of this system on the gas main and hence a bond (connector) exists from being previously installed to make the water and the gas mains electrically continuous to mitigate this previous interference.

Collaborative investigations into what the consequences of increasing the water systems’ current output to 10 Amps would be, found that the gas pipeline drained almost all of the additional protection current through the aforementioned bond.

The protection levels on the gas pipeline, however, remained fairly unchanged and unprotected to the -850mV criterion in AS2832.1:2015.

The 10 Amps of current flowing to the

gas main would be expected to have improved potentials quite substantially, especially close to where the current was being picked up from the water pipeline. However this was not the case. Why? The suspicion was formed that there was an electrical fault along the gas pipeline that was earthing any current being supplied to the gas main from the water main to earth and was hence not protecting either the gas or water main as intended.

The root cause of the problem was determined by conducting a coiling survey. This type of survey consists of a signal being applied to the pipeline in question and an experienced technician tracing this signal along the pipeline path. Any attenuation in the signal or deviation from the expected path can indicate a fault.

In this case the signal diverted from the expected path of the gas pipeline and was found to follow a copper fire

service to a motel. This indicated that the suspected fault had been found and that the problem was the gas main and the fire service pipeline were touching underground and hence earthing all of the protective current from the gas pipeline and, by the same token, the bonded water pipeline.

Figure 2: Copper fire main re-routed through a series of 45o bends and the insulation repair to the gas main.

To confirm and rectify this issue the fault area was excavated which showed that the fire service and the gas main were touching (see Figure 1). The gas main was uncovered and shown to have a very good coating, with the only exception being around where the copper pipe was touching, where the coating appeared to have been damaged during its construction. At this point the pipes were prized apart with wooden wedges to separate them from each other. It was found that the copper service had a small hole in it which was weeping water at the area of contact between the gas and the copper pipeline. Since this pipe was a fire service the damage had to be repaired within 2 days to ensure the integrity of the emergency system in case of a fire. The decision was made that the best way to simultaneously fix the fire service, separate the pipes and also give enough clearance to repair the coating on the gas main would be to reroute the

copper fire service with 45 degree bends around the gas main. The gas main was wrapped with a standard Denso insulation tape and then a PVC plastic tape as shown in Figure 2.

During these isolation works the voltage potential of the gas main was being charted with respect to a calibrated typical copper/copper-sulphate reference cell. These recorded potentials revealed that at the time the fault was removed, at 11:02am, potentials improved instantaneously and the pipeline went from about -750mV to -1150mV and was classified as being protected to AS2832.1 at this location all because of the fault rectification.

These results are shown below.

This not only had good results for the gas pipework, ensuring that their asset was protected from corrosion and that the life of the pipeline was extended, but the water authority has had the flexibility to increase protection and hence asset life through corrosion prevention too. An all-round good solution!
