FEATURES OF TRІBOSYSTEM БрО10С10-ШХ15 WEAR

The article highlights and analyzes the results of tribotechnical and metallographic researches of samples friction surfaces of БрО10С10 from friction pair model БрО10С10-ШХ15. As a result of the research it was determined factors that make influence on tribological properties of these surfaces. In particular it is shown that the ware resistance of the surface details of БрО10С10, in proposed tribosystem, depends on the concentration of lead. Exactly Pb during friction can diffuse from the matrix to the surface details improving its tribological properties. However, the usage such tribosystems for friction that accompanied by cyclic contact loads is unacceptable because there is a possibility of premature destruction of surface bronze parts due to the formation of lead segregation.
