WC 20Cr3C2-7Ni sintered crush metal HVOF coating
1.Excellent abrasion resistance and corrosion resistance 2.Durable impact resistance 3.Excellent bonding strength 4.Use for valves, pumps body and steel industry. thermal spray powder mainly includes WC- based & Cr3C2-based. The WC coating has high hardness, durable wear resistance, abrasion resistance, corrosion resistance and high bonding strength, mainly used in oil & gas valves, mining tools, injection screws and printing machinery parts. The Cr3C2 coating has higher thermal stability and anti-oxidation, which can be used in a high temperature and corrosive environment, e.g. inner- wall of gas pipeline and pump.
