The composite supplies (CM) primarily based on Co, Ti-Cu, and Pt and strengthened with diamond-like carbon particles and diamonds with completely different part ratios have been obtained by high-pressure high-temperature synthesis (5–9 GPa, 800–1800 °C). The strategies of optical microscopy, dynamic indentation, and tribological assessments have been used to ascertain the correlation between the construction and properties of the reinforcing section and CM and to outline the bounds of the applicability of the CM as tribotechnical supplies. Low friction coefficients (0.08–0.06) have been demonstrated by the CM strengthened with a superhard (35–40 GPa) diamond-like section obtained from ball-milled fullerites with a cobalt binder in addition to by the CM with diamonds whatever the binder sort and particle dimension. The wear and tear resistance of the cobalt-based CM will increase with growing hardness of the reinforcing diamond-like particles. The situation for acquiring tremendous wear-resistant CM from metal-fullerene mixtures is the synthesis at a temperature of about 800 °C, which ensures the collapse of fullerene molecules, however limits the graphitization of the diamond-like construction.
