HVOF Thermal Spray Coatings

Service Name

HVOF Thermal Spray Coatings Service

The HVOF process is a combustion process and use Oxygen-and one of several fuel gases including propane,propylene,hydrogen,or Natural Gas. The coating material in powder form,is fed axially through the gun,generally using nitrogen as a carrier gas. The fuel is mixed with oxygen inside the gun  and ejected from a nozzle and ignited outside the gun.The ignited gases surround and heat the powdered spray material as it exists the gun and generates supersonic gas and particle velocities as it propels the molten particles toward the substrate. Due to the high kinetic energy generated and transferred to the particles they flatten plastically as they impact the substrate.
