Great erosion, sliding and fretting wear resistance protection for applications under 1000°F.

Wear resistant thermal spray coatings of tungsten carbide are used for their hardness and wear resistance. When choosing a tungsten carbide powder, the particle size and type of carbide selected are important in determining the correct material to combat various forms of erosion, abrasion and wear. Whereas the amount of metal matrix in the coating (nickel, cobalt, or alloy) will depend on the toughness and abrasion resistance required.

Method: Air Plasma Spray, HVOF Equivalents: WC-106, Stellite JK-114
