High Velocity Oxygen Fuel (HVOF) is one of the most commonly used spray coating 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.
With the HVOF coating process, the gas stream is produced by mixing igniting oxygen and fuel (gas or liquid) in a combustion chamber and allowing the high-pressure gas to accelerate through a nozzle. A powder is introduced into this stream where it is heated and accelerated towards a component’s surface. The resulting thermal spray coating consists of thin overlapping platelets with very low average porosity (< 1 %),
The utilization of the HVOF coating technique allows the application of coating materials such as metals, alloys, plastic, composites and ceramics to produce a coating of exceptional hardness, outstanding adhesion to the substrate material that provides substantial wear resistance and corrosion protection.
Common Applications of HVOF Coatings are: Pumps, Valves, Seals, Actuators, Rams, Impellers, Pistons, Shafts, Bearings, Wear Rings, Landing Gear Legs, Flap Tracks, Gas Turbines Shafts, Pulp and Paper Rollers, Print and Packaging Rollers, Traction Rollers, Agitators and Stirrers.
