FIELD: electrochemical production processes, possibly deposition of bright coatings of nickel-chrome alloy.
SUBSTANCE: process comprises steps of electrolysis of aqueous solution containing nickel sulfate, amino-acetic acid, chrome-potassium alum, 1,4-butynediol, saccharin, boric acid, ammonium sulfate; sustaining pH value of electrolyte in range 2,0 - 5,0; placing non-soluble lead anode in additional anode cell with sulfuric solution having anion-exchange membrane. Method provides increased pH value at generation of chrome (III) hydrate.
EFFECT: stabilized composition of electrolyte, possibility for depositing bright coatings, enhanced buffer properties of electrolyte.
