Structural strengthening of the surface layer material by surface plastic deformation ensures the formation of low roughness, a given depth and degree of hardening, and reduces residual compressive stresses in the surface layers. In the processes of surface plastic deformation by rolling with rollers, the microgeometric and physical-mechanical characteristics of surfaces are formed as a result of deformation of the surface layer of the part under the force of the roller on the surface being processed. In this case, the processes of plastic deformation of the surfaces of parts do not occur throughout the entire volume, but are localized in the zone immediately adjacent to the working profile of the roller in contact with the surface. This requires determining the geometric characteristics of the contact zone and establishing their dependence on the rolling modes. The purpose of this study is to study the influence of rolling modes on the geometric parameters of the surface plastic deformation zone, to determine their optimal ratios for stabilizing the contact zone of the roller and the surface of the part, obtaining a new microrelief of the surface layer of the part, ensuring high quality indicators.
