Cyanidfreies galvanisches Bad zur Abscheidung von Gold und Goldlegierungen

摘要

Cyanide-free electroplating baths for deposition of gold and gold alloy coatings, using sulfurous gold complexes that are stable for a relatively long time, can be used with current densities over 1 A/dm<2> and are practically odor-free, are obtained when the sulfurous compounds used are mercaptosulfonic acids, disulfide sulfonic acids or salts thereof.
