... exposed area of the intermetallics in the pit wall may also increase with aspect ratio and cause the increasee in cathodic partial current, ic, in Fig. 17. Here, as the anodic partial current, ... process. During the pit formation, the aluminum substrate is frequently activated causing increases in anodic currents and decreases in the rest potential. After the pit formation, the aluminum substrate ... susceptibility to pitting corrosion of the 2024 aluminium alloy, Corrosion Science, Vol. 39, No. 3, pp. 495- 510, ISSN 0 010- 938X. Kang, J. Fu, R.
