Description
Summary:The paper examines the tribotechnical characteristics of the Cu-Sn-CuW[O.sub.4]- Mo[S.sub.2] antifriction composite during lubricated and dry friction at sliding speeds 0.5, 1, and 1.5 m/sec. X-ray diffraction of the material and its friction surfaces is conducted and their micromechanical characteristics are determined. The mechanism whereby the composite antifriction material attains the optimal tribotechnical characteristics is explained. It is established that the friction coefficient and wear rate of the composite depend, under varying friction parameters, on changes in the composition, structure, and micromechanical characteristics of the friction surface. Keywords: composite antifriction material, friction coefficient, wear, wear resistance, serviceability, sliding speed, pressure, temperature, structure, micromechanical characteristics, x-ray diffraction, mechanism.
