FIELD: electrodeposition, in particular plating of aluminum and its alloy-based articles.
SUBSTANCE: Claimed electrolyte contains (g/l) zinc sulfate 200-220, nickel sulfate 50-70, sodium sulfate 40-60, boric acid 20-30, sodium fluoride 15-20. Present electrolyte makes it possible to increase both bond resistance and microhardness of coating by 10-20 % and decrease etching time by 25 %.
EFFECT: electroplated coatings of high quality and reduced etching time.
