High Velocity Oxy-Fuel Coatings

Available from Ellison Surface Technologies

Thermal spray coating technique used to create dense, well-bonded surface treatments. In this process, combustion takes place between oxygen and a fuel gas (hydrogen, argon, etc) to produce a high velocity acceleration of energy. Powder particles are then fed into the spray gun's stream and accelerated onto the substrate of the part. The powder partially melts to a molten state while in the spray path, thus creating a bond at impact. The HVOF method produces a coating that is low in porosity and has high bond strength.

Our HVOF coating method uses tightly controlled processing to apply an array of coatings, such as tungsten or chromium carbide, in place of hard chrome.
