High Velocity Oxygen Fuel (HVOF) coating

High-Velocity Oxygen Fuel (HVOF) coating is a thermal spray coating process used to improve or restore a component’s surface properties or dimensions, thus extending equipment life by significantly increasing erosion and wear resistance, and corrosion protection.

Molten or semi-molten materials are sprayed onto the surface by means of the high temperature, high-velocity gas stream, producing a dense spray coating which can be ground to a very high surface finish.

The utilization of the HVOF coating technique allows the application of coating materials such as metals, alloys, and ceramics to produce a coating of exceptional hardness, outstanding adhesion to the substrate material and providing substantial wear resistance and corrosion protection.
