The prediction of corrosion by statistical analysis of corrosion profiles

The corrosion of carbon manganese steel in CO 2-acidified sea water has been assessed by a statistical analysis of corrosion profiles. The total population of depth data was multi-modal and could not be fitted to any well known statistical models. However the deepest pits in the profile followed a type I extreme value distribution. The time dependence of the extreme value distribution parameters has been determined and used to predict the rate of penetration of steel components under pitting conditions.
