- Аннотация: Calculation of diagrams of components of residual stress tensor arising in the surface layer of a tribomaterialunder sliding friction is used to formulate ideas about the role of the medium in creating a plasticizing andstrengthening triboeffect. The characteristics of the structural state of the surface layers of brasses, aluminumand tin bronzes during their friction against steel in surface-active lubricants are presented. The conditions forachieving minimum power losses to friction and wear are determined. The role of local diffusion phenomenain quasi-spinodal phase transitions observed in surface micro-volumes of copper alloys during their contactdeformation is revealed. It is shown that among industrial copper alloys, brass of the L90 type, aluminumbronzes BrA5, BrA7, and tin bronzes BrOF4-0.25, BrOF6,5-0,15 have the greatest wear resistance in sur-face-active lubricants. Examples of implementation of the phenomenon of selective transfer in friction pairsare given. Recommendations are developed for its use in friction units of machines and devices.
