[0002] A metal thermal spraying device is a spraying device that uses flames, electric arcs, plasma arcs, explosion waves, etc. to provide different heat sources. It generates a high-temperature and high-pressure flame flow to instantly heat the material to be made into a coating to a plastic or molten state, and then sprays it onto the surface of a component at high speed to form a coating. The function of metal thermal spraying is to form a layer of coating on the surface of the workpiece to give the workpiece functions such as wear resistance, corrosion resistance, heat resistance, insulation, conductivity, radiation protection, and heat insulation. Metal thermal spraying is used in aerospace, petrochemical, machinery manufacturing and other fields.
