The tungsten carbide powder with cobalt and nickel powder, WC-9Co-5Cr-1Ni 15-45um, also as the HVOF powder. The tungsten carbide thermal spray powder is generally best used to High Velocity Oxygen Fuel (HVOF) spray process. Better corrosion resistance and toughness than WC-Co thermal spray coating. Superior oxidation resistance and corrosion resistance than WC-Co coating. The tngsten carbide coating is widly applied to gate value and relevant component to strengthen wear and corrosion resistance . Its Max. operating temperature 500°C   Spray System   HVOF Coating Micro-hardness   950-1350 HV0.3 Bonding Strength   ≥70MPa Porosity  <1% Deposit Efficiency   45-60%  Maximum Service Temperature    500℃
