Abstract
PURPOSE: To manufacture the above-mentioned coating improved thick adhesive property, corrosion resistance, luster and color tone etc. by electrodeposition, by containing each specific quantity of gold sulfite, soluble copper salt and soluble salt not containing cyanide and alkali sulfite in an electrolyte.
CONSTITUTION: Hard gold alloy coating is electrodeposited on a substrate by using an electrolyte containing gold sulfite (containing 1W30g/l gold), soluble copper salt not containing cyanide (containing 0.1W10g/l copper), soluble salt not containing cyanide (containing two kinds or more of VIII group metals except iron in the limits of 0.1W50g/l each) and 10g/l or more alkali sulfite. Hardness is improved moreover by carrying out heat treatment of the electrodeposited coating at about 250W500°C in vacuum or low oxidative atmosphere.
