The wear resistance of the coatings on the basis of Cu–Mo–S with a copper friction pair was studied by tribological tests in argon and air environment. Microstructure of the coatings was investigated by transmission and scanning electron microscopy. Fiber-globular structure of the coatings was evaluated. Cu–Mo–S coatings can increase the wear resistance of a copper friction pair in ~ 71.7 and ~ 7.9 times in argon and air atmosphere, respectively. Decrease of friction coefficient of copper friction pair from 0.59 to 0.27 (with coating) has been observed during tribological tests in air environment.
