BATH FOR THE GALVANIC DEPOSITION OF A COATING OF A GOLD-INDIUM ALLOY

BATH FOR THE GALVANIC DEPOSITION OF A COATING OF A GOLD-INDIUM ALLOY

Light yellow, glossy and ductile gold-indium alloys which have a good resistance to gradual corrosion by silver sulfide are obtained from electrolytic (galvanic) baths containing 1 to 20 g/l of gold in the form of alkali or ammonium tetracyanoaurate (III), 0.5-50 g/l of indium in the form of a water...

Zusammenfassung:Light yellow, glossy and ductile gold-indium alloys which have a good resistance to gradual corrosion by silver sulfide are obtained from electrolytic (galvanic) baths containing 1 to 20 g/l of gold in the form of alkali or ammonium tetracyanoaurate (III), 0.5-50 g/l of indium in the form of a water soluble indium salt, a buffer or conducting salt and 0.5 to 10 mg/l of selenium and/or tellurium.
