HVOF High Velocity Oxy-Fuel Spray

The high velocity oxy-fuel spray (HVOF) process is a relatively recent addition to the family of thermal spray processes. As it uses a supersonic jet, setting it apart from conventional flame spray, the speed of particle impact on the substrate is much higher, resulting in improved coating characteristics. The mechanism differs from flame spraying by an expansion of the jet at the exit of the gun.  Fuel gases of propane, propylene, acetylene, hydrogen and natural gas can be used, as well as liquid fuels such as kerosene.
