How HVOF Works
The high particle velocity of the High Velocity Oxygen Fuel (HVOF) thermal spray produces coatings that are extremely dense, having a porosity of less than one percent. The High Velocity Oxygen Fuel (HVOF) thermal spray coating has a mechanical bond. The bond strength can be as high as 12,000 psi, which is attained by the high kinetic energy of the particles. This allows the application of dissimilar materials. Additionally, the amount of thermal input to the part being coated is minimal. The substrate temperature stays under 170° C; thus the process does not change the material properties of the parts being coated.
Due to the high density and bond strength, the High Velocity Oxygen Fuel (HVOF) thermal spray coating of tungsten- carbide that we apply is a perfect solution for extreme corrosion and wear environments that need a high wear and corrosion resistant coating.
