Pitting corrosion of aluminum alloy 2024-T3 in NaCl solution was stud ied using electrochemical noise technique. The spectral analysis results showed that the more positive the values of cut-off frequency(fc), the slope of high- frequency linear part of SPD(k) and white noise level(W) are, the more easily th e pit initiates, but none of them can be used to depict the corrosion process in dividually. Two new parameters(SE and SG) were derived by using dimensional anal ysis method, and the value of SE characterize the severity of pitting of corrodi ng material. While the meaning of the other parameter(SG) remains for further in vestigation.
