What types of HVOF spraying equipment are available?


Frequently Asked Questions

All HVOF spraying equipment uses oxy-fuel combustion to heat a coating material, usually in powder form, and to accelerate the heated particles to high velocities before impacting with the substrate.

The major differences between current commercial systems are in use of gas or liquid fuels, water or air cooling, axial or radial powder injection, combustion chamber configuration, nozzle design and length. There are operational differences in combustion pressure, fuel and gas flow rates and powder feed rates. These parameters determine powder particle heating time, velocity and temperature, and ultimately the coating quality.
