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.
