This study is to verify experimentally the validity of the polarization resistance technique that has been introduced previously. The corrosion-loss measurement for brass in natural seawater was adopted as the experimental method. For brass in natural seawater, the potential of maximum polarization resistance, which appeared at o.35V (vs. SEC) on the cathodic polarization curve, was coincided with the optimum cathodic protection potential which was determined by the corrosion-loss measurement. This potential of maximum polarization resistance corresponds to the potential 0.1 V below the corrosion potential of brass in natural seawater. This experimental result supports the aurhor's technique that the optmum cathodic protection potential coincides with the potentiae of the maximum poarization resistance of metal. This optimum cathodic protection potential for brass in natural seawater is in very good agreement with the cathodie protection potential that was recommended by NACE Standard, Federal Register and Shigeno. But it is not in good agreement with the protection potentials that were recommended by Schwerdtfeger, Nagakawa, Crennel, and England Standard of Copper alloys. The tatters are considered as the cathodic protection potentials for special copper alloys.

The optimum cathodic protection potentials of aluminum and its alloys in natural static seawater were evaluated by their potentiostatic polarization resistances. The theoretical optimum cathodic protection potentials obtained in present study were consistent with such empirical values as NACE standard, British criterion, and Nagakawa' s and Ido's propositions. The empirical method which is decided a practical cathodic protection potential by the potentiostatic polarization curve is applicable to aluminum and its alloys as well as carbon steels and copper alloys.
