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
CT 1 CT2 Blade Repairs
Tornado CT1 Blade
• IN738LC Alloy• Strip remaining coating• Weld repair platform seal• Rejuvenation Heat Treatments
– Restore material strength
• Silicon Aluminide
coating – or upgrade
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

Restored microstructure20,000 X magnification
• Stress Rupture test bars demonstrate deterioration of creep strength over time for turbine blades
• Post Rejuvenation

CT1 CT2 Blade Rejuvenation
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
