FIELD: mechanical engineering. ^ SUBSTANCE: reinforcement comprises applying wear-resistant coating and exposing tool surface to pulse high-energy action before and after coating operation. High-energy action combines gas-dynamic treatment of tool surface by plasma jet containing alloying elements, passing electric current through surface layer and coating layer, and abstracting current from work surface. ^ EFFECT: considerably increased efficiency of coating on roll-on tool profiles. ^ 6 cl, 3 tbl, 8 ex |
