Application of molybdenum wire in automobile spraying
The melting point of molybdenum is as high as 2620"C, and has good high temperature performance and corrosion resistance. Molybdenum has strong binding force with steel, so it is the main thermal spraying material in the production of automobile parts. Automobile parts generally adopt high-speed flame spraying of molybdenum wire. The gas mixing injection device of the spray gun produces high temperature gas combustion. The specially designed combustion chamber and gas injection mixing chamber enable the molybdenum wire to be sprayed on the surface of the workpiece at a very high speed before it is completely melted. This process effectively improves the wear resistance of the ground surface and also provides a porous surface for impregnating lubricating oil. It is widely used in the automotive industry to improve the performance of piston rings, synchronous rings, fork, and other worn parts, as well as to repair worn crankshafts, rolls, shaft rods, and other mechanical parts. With the development of Chinese automobile industry, the thermal spraying of automobile gear and other parts will have a great development, and the sales volume of molybdenum spraying wire will increase significantly.
