摘要：

The influence of cobalt chloride concentration, total chloride concentration and sulphate in the electrolyte on cobalt deposition were studied. The current efficiency increased and the overpotential for electrodeposition of cobalt decreased with increasing cobalt chloride concentration. Only minor changes were observed with addition of sodium chloride to the cobalt chloride solution. Sulphate electrolyte resulted in lower current efficiency and higher overpotential for electrodeposition when compared to a similar cobalt chloride electrolyte.
