Abstract: Metal composite materials (CM) are spatially reinforced with superelastic superhard carbon particles, which are synthesised from fullerenes directly upon high-temperature sintering of CM under pressure. The structure and properties of the reinforcing particles and CM based on various metals have been studied as a function of pressure, temperature, and the composition of fullerites. The wear resistance of CM is substantially higher than that of the matrix metal, and the friction coefficient of CM is comparable to that of diamond-like coatings. At the same time, the CM to a great extent retain the electrical conductivity of the matrix metal.

Keywords: composite materials; fullerenes; superelasticity; superhard carbon; nanostructure; wear resistance; friction coefficient.
