HVOF Diamonds
HVOF Coating

dense coatings

HVOF produces coatings that achieve porosity levels below one percent. our in house Lab assures coating quality prior to initiating production cycles.

high bond tensile strength

bond tensile tests are used to test coating adhesion. HVOF has a minimum bond tensile strength of10,000 psi (the limit that the testing epoxy compound is capable of).

wide array of coatings available

HVOF is a mechanical bond coating which readily allows the application of dissimilar materials, for example light-weight aluminum can be coated with tungsten carbide. this allows the machine-ability and light-weight of aluminum but the coated surface has the wear resistance of tungsten carbide. Typical coatings are: Chrome carbide, tungsten carbide, Nickel, Cobalt and blends of other metallic elements. these blends can be customized(by our engineering staff) to suit the demands of your application.

Robotically applied for uniformity

Our programmable seven axis robot manipulates the hvof coating gun and/or your parts to achieve uniform and repeatable coating results.

Typical uses

wear resistance, corrosion resistance and dimensional restorations
