HVOF is a thermal spray system utilizing the combustion of gases, such as Hydrogen or a liquid fuel such as ethanol or kerosene. Fuel and oxygen mix and atomize within the combustion area under conditions that monitor the correct combustion mode and pressure.
The process creates a very high velocity which is used to propel the particles at near-supersonic speeds before impact onto the substrate. One of the basic rules of spraying is that high combustion pressure = high gas velocity, high particle velocity and resulting high coating quality.
