抄録

In 100-times diluted synthetic seawater at 298 K (pH 8.2), the effect of anodizing on the galvanic corrosion resistance of Al coupled to Fe or Type 430 stainless steel was investigated by measuring the galvanic current densities and electrode potentials of the Al. The optimal anodizing conditions for the corrosion prevention of Al/Fe and Al/Type 430 were determined. The results of this study clearly indicate that the increase in the initiation potential of localized corrosion due to anodizing in H2SO4 effectively prevents the atmospheric corrosion of Al coupled to steels.
