PTA/FLAME SPRAY POWDER CAST TUNGSTEN CARBIDE/Ni BASED ALLOY

Blended powders which contain spherical casting tungsten carbide pellets and nickel-based self-fluxing alloy, dark gray pellet. Spherical casting tungsten carbide is spherical or nearly spherical or nearly spherical, it has high hardness((≥2700HV0.1), and excellent wear resistance. Ni-based alloy powder is spherical or nearly spherical, and has good wettability with cast tungsten carbide. PTA surfacing welding layer has good wear resistance, low porosity and Excellent impact resistance. Mainly used in wear resistance, anti-erosion surface or wear repair for mining extraction, oil drilling, machinery equipment, grain and oil equipment etc.
