    Surface thermal spraying alloy powder:

    Metal, alloy, and composite powders commonly used in thermal spraying hard surface technology. By using thermal spraying (welding) methods such as oxygen acetylene flame, plasma flame, or oxygen acetylene explosion flame, these powders are instantly heated, and in a molten or semi molten state, they are sprayed and deposited on the surface of cold or hot workpieces with high-speed heat flow, forming a surface strengthening layer to improve the wear resistance, corrosion resistance, heat resistance, oxidation resistance, or repair the external dimensions of the workpiece surface. This is an economical and practical process technology that has been widely applied.
