High Velocity Oxy-Fuel Spraying HVOF)

High Velocity Oxy-Fuel Spraying Process (HVOF)

HVOF(High Velocity Oxy-Fuel)

In HVOF spraying process, the pressure in the combustion chamber of the spraying gun is increased to generate high-speed flame comparable to detonative combustion flame. The powder materials are feed and melted, or half-melted in the flame jet stream, then accelerated and continuously sprayed at supersonic speed. 


This process allows the formation of coating with extremely high density and high bonding strength. Compared with detonation spraying, HVOF coating has more homogeneous characteristic for its continuous formation process, and exerts more effectively in forming wear resistant coatings with carbide cermets.
