FIELD: electrochemistry. SUBSTANCE: claimed composition makes it possible to obtain chrome films with low resistivity. Electrolyte comprises chromic anhydride, sulfuric acid, saccharose and distilled water. The electrolyte further comprises hydrofluoric acid, boric acid and chromium chloride. The electrolyte comprises the following ingredients (g/l): 500-600 chromic anhydride; 18-20 sulfuric acid; 8-10 saccharose; 100-115 hydrofluoric acid; 3-10 boric acid; 4-5 sodium chloride; and the distilled water balance. EFFECT: improved properties of the chrome plating electrolyte. |
