“…It is enough to give an example of titanium oxynitride, which has already been successfully tested as implants of the organs of the cardiovascular system, although its "components" -nitride and oxidecould not be used in this area. [1] Composite materials, in which carbides, nitrides, carbonitrides, titanium borides are used as a hardening medium, are dispersion-hardened (DHCM). Both the DHCM themselves and their coatings applied to other materials are capable of operating under high mechanical loads, elevated temperatures, and in aggressive environments.…”
