To improve the properties of metal foil compounds based on Al and Cu, it is proposed to use useful impurities with a content of up to 2 at%, which form pseudoalloys with a base. Thanks to this, it was possible to improve significantly physical and mechanical properties, hardness and electrical conductivity. Using a mixed gas of C2H2 + N2, a composite protective coating based on molybdenum with a high hardness has been obtained, and due to the use of the dissolution of saturated solid solutions based on borides of quasibinary TiB2-WB2 systems, functional elements have been obtained that increase their physical and mechanical properties for resistance under load. As a basis for a shockproof protective element, it is proposed to use composites based on SiC ceramics. By optimizing the most important parameters (hardness and crack resistance), the highest values were obtained for composites SiC (Cr) and SiC (Si) Product Description popup.authors Білозеров Валерій Володимирович Бармін Олександр Євгенович Глущенко М.О.
