High Velocity Oxy-Fuel (HVOF) Coating Services

High Velocity Oxy-Fuel (HVOF) Coating is a industrial application method used to increase the hardness and bonding characteristics of many surface coatings and materials. Oxygen and a fuel gas are combusted through a high velocity nozzle with gases such as Hydrogen, Propylene, Acetylyene, and Kerosene.

This industrial process creates coatings with an enhanced adhesion which typically exceedes bond strengths of 13,000 psi. This characteristic of HVOF coatings helps to create the friction reduction properties of the applied coatings in high temperature applications.

The heat and spray pressure of HVOF allow the deposition of materials with high hardness characteristics that further enhance friction reduction, including tungsten carbide, chrome carbide, nickel alloys, cobalt alloys and various carbon and stainless steels. The HVOF process is a preferred technique for spraying wear-resistant carbides and is also suitable for applying wear-and/or corrosion-resistant alloys like Hastelloy, Triballoy, Chrome Super Alloy 13 and Inconel.
