Study of effect of roller and part parameters on quality of surface layer after surface plastic deformation by rolling

The influence of the geometric parameters of the roller and the part under surface plastic deformation by running-in on the properties of parts is investigated. When choosing rollers for running-in, it is proposed to use a conditional parameter — the coefficient of curvature of contacting surfaces. The relationship between the parameter of the curvature coefficient and the quality of the surface layer after running-in has been experimentally confirmed.
