Abstract
The gold–indium alloy system has a number of intermetallic, differently coloured phases, of interest to the jewellery industry, and giving rise to the name blue gold. The present study is aimed at finding out the effect of electrolysis conditions on the morphology, elemental and phase composition of the Au–In alloy coatings from different electrolytes – with cyanide, acetate and glycine – as well as establishing the conditions for formation and observation of spatio-temporal structures on the surface of the electrode, similar to those observed during the electrodeposition of other indium alloys with silver, cobalt and palladium. It was established, that blue coloured matt coatings could be obtained from acetate–citrate electrolytes and the process of electrodeposition of gold–indium alloy from glycine electrolytes is a very promising one because of the possibility to obtain a variety of spatio-temporal structures on the surfaces of the electrode which could allow the comparison with other known cases of electrodeposition of similar structures in many other alloy systems.
