ABSTRACT:
There are needed galvanic baths for the deposition of silver and silver alloys which exhibit a high resistance to sulfur and contain the least possible amounts of alloyed platinum group metals and/or gold. This is attained by using a salt melt as the electrolyte which melt contains a silver salt, alkali thiocyanate and salts of at least one alloying metal. Preferably the electrolyte contains per liter of salt melt 0.1 to 40 grams of silver and 1 to 200 grams of platinum metal and/or gold.
