HVOF Tungsten Carbide Coated Screw with Through Hardened Steel

Special HVOF Tungsten carbide Coated Screw with Through Hardened Steel

 

HVOF (High Velocity Oxygen Fuel) coating process is a kind of thermal spraying technique that melted (or heated) materials are sprayed into the surface. By HVOF technology, alloy powder spraying is under high pressure and high velocity. The adhesive force is over 10000PSI, and the powder density can be achieved up to 99.8%, which offers outstanding performance in wear & corrosion resistance.

 

Screws with HVOF Tungsten Carbide coating are generally used for processing plastics with high injection temperature and extremely wear-resistanct requirements.
