Laser Powder Cladding for the Repair of Industrial Components, Including Gas and Steam Turbine Components

TMC provides consulting services in laser materials processing, including cutting, welding, cladding, transformation hardening, engraving and marking.  

One of the fastest growing and probably technologically most challenging technologies is Laser Powder Cladding (LPC). LPC process provides unique, versatile method of restoring or even upgrading the original properties of damaged parts.

Several components such as blades or vanes of the gas and steam turbine can be rebuilt using the LPC process. It is used for automated repair of cracks and rebuilding of worn sections.

Examples:

	Steam pressure control valves can be rebuild and protected from the severe corrosive environment
	Erosion shields for the steam turbine LP blades
	Hydraulic piston & cylinder repair
	Repair of various gas turbine components
	Protective layers for boiler and heat exchanger tubing

Typical laser clad materials include the following:

	Metal matrix/WC, SiC, Cr3C2 (up to 80% vol. of carbide) and metallic layers
	Intermetallic layers such as: Ni3Al, Ni3Al + Al2O3, Ni3Al + ZrO2 and MCrAlY
	Superalloys such as Waspaloy and various Ni-based alloys such as C276, IN625, IN718 and IN738
	Single crystal (SX), and directionally solidified (DS) materials such as CMSX-4, Mar-M 509 (SX), and Mar-M 247, Mar-M 509 (DS)
	Stellite 21, Stellite 6, Stellite 6B and various Stellite 6/carbide compositions
	Tribaloy 400 and 800, Armacor M
