抄録

Statistical and stochastic aspects of localized corrosion such as pitting corrosion and stress corrosion cracking have been reviewed and discussed. Stochastic theory was introduced to rationalize time dependent pitting process and distribution of pitting potential. A birth and death stochastic process was found properly to describe the generation and repassivation process of pitting. The stochastic analysis could provide rational estimates of the pit generation rate and repassivation rate, which, in turn, decide pitting potential. Statistical analysis of spatial distribution of pits for evaluation of atmospheric exposure test and recent advances of extreme value analysis were discussed.
