Quantitative interpretation of impedance spectra with the Mixed-Conduction Model furnishes estimates of kinetic and transport parameters of the corrosion and anodic oxidation processes. The results indicate a beneficial effect of Pb addition on general corrosion regardless of crevice solution composition.enArticle
