FIELD: process engineering.
SUBSTANCE: invention relates to machining of parts from ferrous alloys containing at least 80 wt % of iron or from unalloyed steel for kitchenware for antiscore properties. Nitration or carbonitriding at 592-750°C are conducted to facilitate the creation of nitrous austenite ply between nitride and diffusion plies, oxidation is made to facilitate the conversion of at least a portion of nitride austenite into the phase of higher hardness. The latter is nitride braunite or nitride martensite. Note here that higher hardness is a mid magnitude between nitride ply hardness and that of diffusion ply.
EFFECT: higher burnt-on, anti-abrasion and corrosion resistance properties, lower production costs.
