WC-CrC-Ni This product is dark gray spherical powder. The spheri-city of the powder is better, which ensures good fluidity. The holes on the sphere are more uniform, so that the powder can be heated uniformly in the flame. 

Coating properties:  

Micro-hardness: 1000-1200Hv

Porosity: less than 1%

Combined strength: above 70MPa

Applicable temperature: less than 766 degrees Celsius under oxidizing atmosphere

Characteristics and applications:

Besides high wear resistance, WC-20Cr-7Ni is also resistant to high temperature, hydrogen sulfide, brine and cavitation corrosion. It can be used normally in saturated brine. For example, screw drill and chemical equipment in petroleum machinery require more oxidation resistance and corrosion than ordinary cemented carbide, and can withstand high temperature (766 degree) and wear resistant coating. The coating can be sprayed with WC-20Cr-7Ni powder twice the speed of sound .
