FIELD: metallurgy.
SUBSTANCE: invention relates to the field of metallurgy, and more specifically to the formation of corrosion- and wear-resistant coatings with high density and hardness. The method for hardening a cylindrical product coated using surface-plastic deformation involves uniform movement of the coating relative to the deforming element, while two deforming elements are positioned opposite each other and act on the coating through surfaces that repeat the curvature of the coating surface, with a compacting pressure of 1-10 kg/mm2 at a relative speed of movement between the deforming elements and the coating of 1-3 m/s and the supply of protective gas into the deformation zone.
EFFECT: production of a coating with 100% density and microhardness equal to the microhardness of the original monolithic material used for spray coating.
