COBALT–INDIUM ALLOYS ELECTRODEPOSITION FROM CITRATE ELECTROLYTE AND SPATIO–TEMPORAL PATTERNS FORMATION
L. Veleva, M.A. Estrella–Gutiérrez, Ts. Dobrovolska and I. Krastev
Cyclic voltammetry was used to compare the mechanism of the electrodeposition of In, Co and Co–In from citrate electrolytes.
It was established a strong relation between Co–In phase composition and the electrolysis conditions.
At higher current the alloy phase of CoIn3 is formed, besides that of In. Minority phases are Co and Co(OH)2.
Specific patterns (waves, targets, spirals) considered as space–time structures were obtained onto Co–In alloy surfaces.
The formation of this patterns occur in the limit of diffusion.
