Bath for the electrodeposition of silver-gold alloys

摘要

Silver-gold and silver-gold-tin alloys can be deposited at a high rate from electroplating baths which comprise, in addition to silver as dicyanoargentate, gold as dicyanoaurate and, if appropriate, tin as a soluble tin(II) compound, the potassium salt of gluconic acid, glucaric acid and/or glucuronic acid as complexing agent.
