Abstract

FIELD: metallurgy, particular, thermochemical treatment in gas media; applicable in mechanical engineering for increase of corrosion resistance of machine parts made of nonalloyed electrical- sheet steel. SUBSTANCE: method for thermochemical treatment of articles made from electrical-sheet steel includes their heating in the air, gas nitriding and cooling. Heating is carried out up to 800-900 C with subsequent isothermal holding at this temperature in the air. Nitriding is combined with cooling which is effected in flow of ammonia. Treatment by the offered method increases the article corrosion resistance by 6-8 times as compared with the known method, with improvement of magnetic properties by 1.5-2 times. EFFECT: higher corrosion resistance of articles with preserved magnetic properties. 1 tbl
