FIELD: process engineering.
SUBSTANCE: invention relates to machine building, particularly, to physicochemical hardening of parts. First, part surface is conditioned by turning to remove 200 mcm of surface layer, not larger, to produce clean juvenile surface and reduce strain hardening of part surface. Second, simultaneously, part surface is hardened and plastic metal layer is applied thereon by deforming ball containing copper whereon working fluid is forced. Said working fluid contains chemical copper compounds to initiate selective transfer in contact between said deforming ball and parts surface via aforesaid surface layer. Turning element and deforming ball are located in tangential plane at distance that allows minimum interval of contact between juvenile surface and ambient medium before application of plastic metal layer.
EFFECT: higher efficiency of machining.
