The results concerning an influence of surface plastic deformation (SPD) of erosion coatings from hard wear-resistant, soft antifriction materials and combined electro-erosive coatings (CEECs) on the indicators of layers’ quality are generalized. As shown, the applications of CEEC, which includes a formation of copper underlayer for hard wear-resistant coatings, allows to reduce the tensile stresses and to increase the fatigue strength. The performance of the SPD leads to favourable compressive stresses in the surface layer. The dependences of surface layers hardness on the specific strain force are founded. As determined, the rational specific strain force of SPD are 1000 MPa for diamond smoothing and 1500 MPa for running in ball.

Key words: electro-erosive alloying (EEA), combined coating, plastic deformation, structure of surface, microhardness.
