A metal surface processing technique that heats and sprays the sprayed material until it dissolves, atomizes it through high-speed airflow, and sprays it onto the surface of the part to form a spraying layer. According to the different heat sources used. It can be divided into flame spraying, arc spraying, plasma spraying, detonmion spraying, etc. There are many kinds of spraying materials, such as zinc, aluminum and its alloy and plastics used for surface corrosion protection - cermet and ceramics used to improve surface wear resistance, corrosion resistance and high temperature resistance. thermal spraying has basically no restrictions on the overall dimensions of workpieces, with relatively low production costs and increasing mechanization and automation. It has become an increasingly widely used surface technology, which is widely used in large-area corrosion resistant coatings, wear and corrosion resistant coatings for various mechanical parts, thermal corrosion resistant coatings for high-temperature parts, etc. It can also be used for repair of wear failure parts, A-melt alloy spray welding, etc.
