Abstract
The corrosion of lead and its alloy anodes in nickel sulphate electrolyte with and without cobalt was studied for the electrolytic conditions as to the kinds of electrode, time, current density, bath temperature, concentration of cobalt, etc.
From the research, it was found that the presence of cobalt ion in nickel sulphate electrolyte lowered the anodic potential of lead, but the corrosion of lead anode was not reduced.
In 1938, M. Rey and others reported that the presence of cobalt in sulphate electrolyte very much reduced the corrosion of lead anode. But it seems that the effect of the presence of cobalt does not necessarily reduce the anode corrosion depending upon the electrolytic conditions.
