Abstract:

The spontaneous corrosion of magnesium was enhanced by impressed anodic current. The protective film breakdown associated with the anodic current was found to be a rather slow process. The apparent activity of magnesium was sharply reduced by the addition of twenty five atomic percent of cadmium. Anodes of this binary alloy operated at an efficiency of 100 but at a potential of only -0.8 volts versus the saturated calomel electrode. Anodic tran sient potential data corresponded in general to an electrode under protective film control. All attempts to minimize or eliminate the spontaneous corrosion reaction with MgAc2 electrolytes failed. The performance of dry cells was poor when salts of aromatic acids were employed for the electrolyte.
