WC-20Cr3C2-7Ni 5-30um Tungsten Carbide Thermal Spray Powder

Thermal spray powder WC-20Cr3C2-7Ni 5-30um is generally best using High Velocity Oxygen Fuel (HVOF) spray process. Choose higher carbide content for higher hardness and resistance to fretting, abrasion and particle erosion. Tungsten carbide powder is used for turbine components: air seals, baffle dampers, nozzle supports, valve seats, struts. Thermal spray coating with best price can be also used for crushing rolls, forming dies, forging tools. The HVOF powder service up to 750 °C. Spray System HVOF/HVAF/APS Coating Micro-hardness 1000-1400 HV0.3 Bonding Strength ≥70MPa Porosity ＜1% Deposit Efficiency 45-60% Maximum Service Temperature 750℃
