WC-15NiCr Thermal Spray Powder
- Agglomerated and Sintered gray-black spherical or near-spherical particles with good flowability.
- The maximum service temperature is up to 500℃.
- The density coating has high hardness with excellent resistance to abrasive wear, sliding wear, erosion wear, and cavitation.
- NiCr has better corrosion resistance than Cobalt, CoCr, and excellent resistance to seawater (Saltwater) corrosion.
- Mainly used in oil field equipment, ball valves (oxidizing environment), hydraulic gate levers, transportation container hydraulic levers, the petrochemical industry, offshore equipment, parts, etc.
