Advanced Repair Processes

Advanced Repair Processes to Extend Component Life

• Rejuvenation Heat Treatments to restore high-hour CT Blades strength and properties

• Repair cracks in difficult to weld IN738 and IN939 alloys with LPMTM high strength powder metallurgy process

• Specialized coating stripping

and re-coating processes

TB5000CT1 Blade

CT1 CT2 Blade Rejuvenation

• Specialized heat treatments to restore service aged alloy microstructure

• Solution and re-precipitation of critical gamma prime phase to as-new microstructure

• Full restoration creep strength and of properties

CT1 Turbine Vane Repairs

• IN939 Alloy• Strip remaining coating• Weld/LPMTM repair cracking damage

– High Strength LPM Superalloy

• Silicon Aluminide coating• High Performance

Platinum Aluminide

coating upgrade

High Strength LPMTM Process

• LPMTM Powder Metallurgy repair process• Select filler materials for higher strength• Advantages over welding

– Non fusion process eliminates HAZ cracking– Distortion free heat treatments– High strength superalloy material

LPMTM – for High Strength

• For nickel parts, the LPM repair material is stronger than conventional weld repairs
