Method and electrolytic bath for the deposition of low carat bright gold-silver alloy coatings

Method and electrolytic bath for the deposition of low carat bright gold-silver alloy coatings

Bright, low carat gold-silver-alloy coatings which are ductile and have a thickness up to over 100 mu m are obtained from an electrolytic bath containing 0.5 to 25 g/l of gold in the form of alkali gold cyanide, 0.25 to 15 g/l of silver in the form of alkali silver cyanide and 10 to 200 g/l of alkal...
