What is HVOF? High Velocity Oxygen Fuel?
What is HVOF spray?
HVOF is a High Velocity Oxygen Fuel. The HVOF is a combustion process. HVOF fuels can be: Hydrogen, Propane, Natural Gas or a liquid fuel such as kerosene.
The combustion process generates a very high velocity gas stream. The gas stream propels the powder particles at near supersonic speeds.
HVOF key benefits are the extremely dense and low oxide coatings. Low oxides: Since the powder particles spend less time in the flame, and lower flame temperature 3,000 °C compared with plasma spray: HVAF (high velocity air fuel) has an even lower flame temperature than HVOF, and produces coatings that are even less oxidized, and more ductile.
As well as producing excellent bond strength, some HVOF coatings can be sprayed very thick due to the exceptionally high velocities producing coatings in compression instead of tension.
