Abstract
Probabilistic nature is intrinsic for localized corrosion and important for evaluating the corrosion loss in laboratories or practical fields, so that several types of probability distribution function (pdf) were reviewed with examples of corrosion data. Normal, log-normal, Poisson, and exponential type of pdf were described for evaluating pitting potential, crevice potential, pit density, pit generation time, or failure time of stress corrosion cracking. Wide applicability of the extreme value distribution was emphasized. Recent works using Weibull pdf was suggested to bridge the gap between laboratory and field data of localized corrosion.
