Summary
The composite supplies (CM) based mostly on Co, Ti-Cu, and Pt and bolstered with diamond-like carbon particles and diamonds with totally different element 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 checks had been used to determine the correlation between the construction and properties of the reinforcing part and CM and to outline the boundaries of the applicability of the CM as tribotechnical supplies. Low friction coefficients (0.08–0.06) had been demonstrated by the CM bolstered with a superhard (35–40 GPa) diamond-like part obtained from ball-milled fullerites with a cobalt binder in addition to by the CM with diamonds whatever the binder kind 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.
