Development in the Study on Corrosion Probability and Extreme Value Statistics

Abstract

Development in the study of corrosion and extreme value statistics in Japan has been described. Professor Noboru Masuko had published a review paper on “Corrosion and Probability” at 1972, followed by the development of the extreme value theory in the field of corrosion science and corrosion technology. Various types of probability distribution observed in corrosion have been discussed. Estimation of the maximum pit depth or the analysis of the surface area dependency of pit by Gumbel distribution and Weibull distribution for the analysis of stress corrosion failure time have been discussed.
