FIELD: electroplating, mechanical engineering, instrumentation engineering and other engineering fields. SUBSTANCE: process is carried out in electrolyte based on chromic anhydride, sulfide acid and trichloroacetic acid within the range of varying of chromic anhydride concentration of 60-120 g/l with weight ratio of chromic anhydride to sulfuric acid of 100:1 and range of variation of concentration of trichloroacetic acid of 0.5-0.9 g/l. EFFECT: reduced concentration of chromic anhydride, and improved quality of coatings. 1 tbl
