“…Analyzing the obtained results, it can be assumed that diamond smoothing significantly increases the value of residual stresses in the surface layers due to an increase in the dislocation density. These findings coincide with the results in numerous works [2,3,[6][7][8]13,16,21]. Since residual stresses significantly affect wear resistance, a reserve is created after combined processing to increase wear resistance.…”

“…Technological heredity is manifested particularly vividly in combined processing methods, when technological factors sequentially and simultaneously affect the work part. Moreover, heredity not only has an effect immediately after the finishing operations of the technological process, but can also occur during the operation as a result of the effect of certain surface quality parameters created in the surface layer of the part during its previous processing [1,2,[9][10][11][12][13][14][15][16][17][18].…”

The purpose of this research was to analyze the change in residual stresses in the surface layer of steel samples taking into account the technological heredity effect on the value and sign of residual stresses. An installation of combined processing was developed. Combined processing consists of sequentially performing electromechanical processing and diamond smoothing. All areas of the samples were studied—after machining (i.e., in the initial state), after electromechanical processing, and after diamond smoothing. The research shows that the sign and value of residual stresses are significantly affected by the combined processing modes. The main parameters of the surface layer are formed at the final stage of the combined processing–diamond smoothing. This paper gives recommendations on the use of combined processing for power plant parts.
