Аннотация:The main solutions of typical elastic-plastic problems (including the tribocontact one) of physicochemical mechanics for surface-plasticized and surface-hardened materials are reviewed. The influence of surface-active media and residual stresses arising in the near-surface layers of solids after the ‘loading-unloading’ cycle of the real material structure, including distributions of linear and point lattice defects in soft and hard structural material components, is analysed. The role of the Rehbinder effect in establishing the antiwear mode of working conditions for real sliding tribopairs is shown by particular examples.
