FIELD: electroplating, mechanical engineering, instrumentation engineering and other fields of engineering. SUBSTANCE: process is effected in electrolyte based on chromic anhydride, strontium sulfate, strontium compounds (oxide, hydroxide, carbonate and chromate) introduced for reducing of strontium sulfate and artificial technical cryolite at 70-120 g/l of CrO<SB>3</SB>. Concentration of compound introduced for reducing of solubility of strontium sulfate is determined from weight ratio of <EMI ID=0.172 HE=9 WI=18 TI=CHI>=250=270 with subsequent conversion for the compound formula. EFFECT: improved appearance of coatings. 1 tbl
