Abstract
Pitting corrosion is a localized corrosion that leads to potential damage to metal structures. The goal of this work is to provide a model for pitting corrosion risk management. The process of pitting corrosion is considered as a combination of pit initiation and pit depth growth. For the pit initiation, a Poisson process is used in which an average pit density is developed to simulate a linear or non-linear pit density pro¿le over time. For the pit depth growth, we use a nonhomogeneous Markov process with the maximum pit depth growth rate depending on time. As benchmarks against experimental results, the mean maximum pit depth and the variance are predicted using statistical methods and these match well with the experimental data. A sensitivity study of the parameters in the pit initiation and pit depth growth models is provided. A Monte Carlo method is also discussed as another method for simulating pitting corrosion.
