Cr3C2-37WC-18NiCoCr Thermal Spray Powder
- Agglomerated and Sintered gray-black spherical or near-spherical particles.
- The maximum service temperature is up to 700℃.
- The coating has excellent resistance to sliding wear, abrasive wear, erosive wear, corrosive wear, cavitation, and corrosion.
- Excellent resistance to solid, liquid, and gas corrosion in elevated temperatures.
- Excellent resistance to high-temperature complex corrosion.
Mainly used in pump valve parts, power generation boilers, biomass-burning boilers, the chemical
