HVOF Thermal Spray

The High Velocity Oxygen Fuel (HVOF) spray process efficiently combusts oxygen and a gaseous or liquid fuel to produce high kinetic energy while controlling the heat input. In this process, the coating material, which is in powder form, is introduced into the hot gas stream and uniformly heated until it reaches a molten or semi-molten condition.

The combination of high particle velocities, uniform heating, and low dwell time results in coatings that are dense and tightly bonded to the substrate. This process ensures more predictable coating chemistries and creates extremely wear-resistant coatings with fine, homogeneous microstructures, making it ideal for industrial valves and critical plant components.
