FIELD: production of steel articles with metallic coat. SUBSTANCE: method involves machining; carbonizing internal surface of cylindrical articles in gaseous medium to eutectoid state; providing thermal treatment for obtaining troostite structure and chrome plating prior to finial machining. EFFECT: improved operating characteristics of cylindrical articles by increased chrome adhesion strength of chromium coating and basic metal and improved hardness of basic layer under coating.
