The Moscow Institute of iron and steel alloy, a State Research Technology University of Russia, has developed an efficient protective coating to prevent the wear of automobile and tool parts The protective coating can prevent wear, oxidation and corrosion of automobile parts and metal processing tools Spraying coating is helpful to improve the performance of basic materials, extending the service life of milling cutter, cutting blade, drilling cutter, reamer, punch and high load friction component parts (transmission of bearing, shaft, gear and gearbox) by several times The results were published in the International Journal of ceramics "Our goal is to produce a protective coating for products sprayed in a vacuum chamber using plasma precipitation technology Under the action of gas discharge, titanium, nickel, aluminum and carbon atoms transfer to the product surface and react with nitrogen to form a hard protective coating " Yevgeny Levashov, head of the Department of powder metallurgy and functional coatings, said that the protective layer can reduce the friction coefficient in the cutting area, improve the wear resistance and thermal stability of the coating, reduce the harmful impurities discharged into the atmosphere, and thus improve the efficiency of metal processing.
