Abstract
The possible synthesis of hexagonal titanium carbohydride—copper composites by two- and three-stage mechanical activation of titanium and copper powders in liquid hydrocarbon followed by magnetic-pulse pressing has been studied in this work. Surfactant used for the three-stage synthesis enable one to restrain the formation of intermetallic phases in the process of mechanical activation and reduce the fraction of intermetallic phases in consolidated samples. The density, microhardness, abrasion resistance, and wear parameters under conditions of dry friction with a steel ball have been estimated. Two- and three-stage methods of producing powders have been shown to be preferable, since friction coefficients and wear in friction pairs are much lower than that of composites produced by the one-stage method.
