Translated from Metallurg, No. 10, pp. 91–97, October, 2016.
Development of compositions and application of coatings by cold gas-dynamic deposition from powders prepared by means of a micrometallurgical method is studied. In addition, use of mechanical alloying technology is substantiated during composite powder preparation based on aluminum for creation of wearresistant coatings. Results are given for the effect of reinforcing component concentration and powder composite preparation method on the main wear-resistant coating properties for a metal–nonmetal system. Results are provided for an experimental study of adhesive strength, microhardness, porosity, and wear resistance of coatings made from powder matrix material of the Al–Sn–Zn system prepared by a micrometallurgical process of high-speed melt quenching, and also composite powder of the system Al–Sn–Zn–Al2O3.
