METHOD OF HARDENING PRODUCTS FROM STEEL AND CAST IRON BY BORIDING AND SUPPORTING,. It is noted that, with a chain of sevyshenov in the working resource of the treated vkotpii due to the proliferation of local boric and sulfide layers, before applying boring, a regular macrorelief is applied to the surface of the products, borvane is carried out to a depth less than the height of the macrorelief, then the grinding the depth of the protrusions of the macrorelief, and the sulfidation is carried out in compositions neutral to the boride route. |
