Abstract: Electroreduction of Co(Ⅱ) to Co in acetami de-urea-NaBr melt at 353K is irreversible in one step. α and D are determined as 0.23 and 2.24×10-7cm2·s-1. Y(Ⅲ) is not reduced to Y alone, but can be inductively codeposited with Co(Ⅱ). The amorphous Y-Co alloy film was obtained by potentiostatic electrolysis. The content of yttrium in the yettrium-cobalt deposits changes with the cathode potential, molar ratio of Y(Ⅲ)/Co(Ⅱ) and the electrolysis time, and can reach 83.93%.
