HIGH VELOCITY OXYGEN FUEL (HVOF)

Powered Coating That Packs A Punch

The ultimate wear-resistant coating, HVOF delivers a premium finish. 


Our High Velocity Oxygen Fuel (HVOF) offers a dense, low porosity coating that provides better wear resistance, increased hardness, higher bond strengths, and more protection than other coating solutions. In fact, our premium HVOF coatings can produce deposits with less than 1% porosity.

GOOD TO KNOW

At New Metal Surfaces, HVOF coatings are completed using advanced automated machinery (6-axis KUKA robot on a 7th axis linear track, if you want to get technical). This allows for smooth, even coating to all components — every time. It also means we complete projects quickly, without sacrificing a premium finish, and get your components back to you sooner.

Tech talk

Using our 6-axis KUKA robot on a 7th axis linear track, we apply HVOF coatings by mixing fuel and oxygen, which is fed into a combustion chamber and ignited.


The generated gas has an extremely high temperature and pressure, which is ejected through a nozzle at high speeds. Next, powder is injected to the gas stream, and that powder partially melts. Lastly, the stream of gas and powder is directed towards the surface to be coated.
