WC-10Co4Cr Thermal Spray Coating Material
Product description
Agglomeration sintering or sintering crushing of gray/black particles; Agglomerated sintered particles are spherical or nearly spherical, with good flowability; Sintering and crushing into irregularly shaped particles;
The maximum working temperature is 500 ºC;
A hard and dense coating that is resistant to abrasive wear, corrosive wear, and erosive wear;
Replace electroplated hard chromium;
Mainly used in aircraft landing gear, gate valves and ball valves, paper rollers, hydraulic cylinders, compressor rods, metallurgical rollers, mechanical components, etc.
