| Summary: | Surface engineering allows you to change the physical and chemical properties of the surface layers of materials by modifying or applying protective coatings using various methods. Plasma technologies are widely used in various branches of engineering to produce hardening, wear-resistant, heat-resistant, corrosion-resistant, protective and decorative and other types of coatings that significantly improve the performance properties of products. In this work the results of laboratory studies of the physical and mechanical properties of Ni-B-Cr-Si coatings deposited by supersonic plasma deposition on an aluminum substrate are presented. It is shown that the use of this method of modification of metal surfaces is advisable.
