LPM ® - Liburdi Powder Metallurgy
Mechanical Design & Engine Performance
Stress in Ksi
The unique Liburdi Powder Metallurgy, LPM®, is a patented, advanced joining and cladding process for blades, vanes and other superalloy turbine components. LPM® offers superior strength and performance compared to conventional weld and diffusion braze repair methods. The LPM® process uses mechanical means to remove the crack-damaged areas. Inspections ensure that all weakened material has been removed before the LPM® materials are applied at room temperature using either a moldable putty or a flexible tape composition. The parts are then heat treated in a vacuum acuum Larson Miller Plot of LPM® Material and Vane Alloy Alloys furnace to produce a liquid phase sintered, metallurgical bond 100 with the base alloy. The process is very versatile and materials aterials GTD222 can be formulated from a wide variety of high strength LPM® superalloy powders selected for the specific application, on, e.g. X40 10 IN738, Rene80, Mar M247, X40. Compositions can IN625 WELD also be designed for wear resistance using Chrome Carbide or abrasive tip materials. 1 45 45
Blade Repairs For nickel based blade superalloys such as IN738 and GTD111, matching powder alloys can be used for higher strength crack free repairs. The LPM® strength exceeds that of conventional weld alloys allowing for high reliability and more extensive repairs. For the latest high performance engines, the process is used by the OEMs to apply an “engineered” blade tip consisting of abrasive oxidation resistant alloys to single crystal airfoils and for closing the cavities that are used to support the internal ceramic core during the casting process.
