High-Velocity Oxy-Fuel Spray (HVOF) Thermal Spray & Hardfacing
High Velocity Oxy-Fuel (HVOF) is a thermal spray hardfacing technique used to apply high-quality and dense coatings onto various surfaces. It involves the combustion of fuel gases (typically hydrogen, propane or propylene) and oxygen, in a combustion chamber.
During the HVOF process, The combusted gases exit through an expansion nozzle which produces the high-velocity gas stream. A metallic powder is then introduced axially into the high-pressure combustion chamber. The powder particles are heated in this high-velocity gas stream and transferred with high kinetic energy to the surface of the workpiece, forming a dense coating with excellent bonding properties.
