Development of technology for obtaining nanostructured composite powders by high-speed mechanosynthesis

Abstract

The results of the development of technology for obtaining nanostructured composite powders in two ways – surface reinforcement and cladding are presented. The possibility of manufacturing functional coatings based on the obtained powders by the method of supersonic cold gas-dynamic spraying is shown. The characteristics of the resulting coatings (adhesive strength, microhardness, wear resistance, low porosity) were studied. The real prospect of using the created functional protective coatings for precision engineering is shown.
