High-Velocity Oxygen-Fuel (HVOF) Spraying Equipment

The High-Velocity Oxygen-Fuel (HVOF) spraying equipment is a high-end thermal spraying device that utilizes high-temperature supersonic flame jets generated by the mixed combustion of fuel and oxygen to heat spraying powders to a molten or semi-molten state, followed by high-speed projection onto the workpiece surface for preparing high-density and high-bond-strength wear-resistant and corrosion-resistant coatings. Its core advantages lie in the low-temperature and high-velocity spraying characteristics, which can not only effectively inhibit the decomposition of cemented carbide powders during the spraying process, but also ensure that the coating porosity is less than 1% and the bonding strength reaches over 80 MPa, rendering the overall coating performance far superior to that of traditional spraying processes.
