Current development of motor-tractor engineering and special-purpose machinery requires increasing the energy load of friction units, smooth switching on and standing start, and increasing the service life. This is achieved both by the control system of the friction unit and by changing the composition of the friction material. The analysis of scientific and technical literature of compositions of composite copper-based friction materials to operate in conditions of boundary friction showed that there is no data on the wear features, the formed friction surface, and the wear mechanisms of the material containing titanium powder. The paper presents the results of evaluating the effect of titanium powder content on the formation of the friction surface, the features of run-in and steady wear. It was found that during the sintering of the friction material with the addition of titanium powder, a complex compound in the form of carbide and carbonitride is formed on its surface, which makes it possible to increase the coefficient value and wear resistance.
