发明名称 Process for the electrolytic deposition of gold and gold alloy coatings and compositions therefore
摘要 For the electrolytic deposition of gold alloys there is required a process with which low carat coatings can be deposited which nevertheless have a high resistance to tarnish. Such coatings are obtained from electrolytes which consist of a salt melt and contain gold salts, alkali thiocyanate and salts of one or more alloyings elements as constituents. Preferably the electrolyte contains per liter of salt melt 0.5 to 20 grams of gold, up to 300 grams of Cu, Zn, Sn, Cd, Ni, Ag, Pd, Ru and/or Pt, up to 200 grams of alkali cyanide and/or water.
