Аннотация: Within the framework of physicochemical mechanics (the Rehbinder effect), the problems of theplasticizing and strengthening effect of the lubricating medium on the near-surface layers of metal triboma-terials are analyzed. The influence of modeling (petroleum jelly oil, glycerin, mineral oils, glycerin-basedhydraulic fluids) and industrial (Buksol, Puma, and M-14V2) lubricant media that contain surfactants, isinvestigated on the main tribological (coefficient of friction, wear intensity), strength (yield strength, micro-hardness) and microstructural (broadening of X-ray lines, dislocation density and crystal lattice parameter)characteristics, as well as on the processes of diffusion redistribution of alloying elements in surface layers oftribomaterials, such as copper, brass, and bronze, when they are rubbed together with steel. The analysis ofthe conditions of formation and stable functioning of the regime of “non-wear” friction in these tribomate-rials is carried out. It is shown that among industrial copper alloys, brass of the L90 type, aluminum bronzesBrA5 and BrA7, and tin bronzes BrSnP4-0.25 and BrSnP6,5-0,15 have the greatest wear resistance in surface-active lubricants. Examples of the implementation of the selective transfer mode in tribo-pairs used in railwayand motor transport are given
