Abstract—

The paper presents the results of a study on how the addition of titanium powder affects the tribotechnical properties of a copper-based powdered friction material when operating under friction boundary conditions. It is shown that the introduction of 5–25 vol % titanium powder increases the friction coefficient from 0.054 to 0.096. This is due to the formation of a layer of carbide, carbon nitride, and titanium nitride on the surface of a titanium particle during sintering of the friction material, as well as an intermetallic compound of the titanium-copper system up to 6 μm thick with a microhardness of 4000–3000 MPa. The data obtained made it possible to develop a friction material that increases the service life of oil-cooled brakes.
