FIELD: ferrous metallurgy. SUBSTANCE: steel parts are subjected to surface alloying with nitride-forming elements using laser heating, after which parts are nitrogenized for 29 hr in ammonia medium at 540 C and then annealed at 600 C for 20-40 min. EFFECT: increased surface strength of parts. 1 tbl, 5 ex
