Monte Carlo Simulation of Localized Corrosion

George Engelhardt, OLI Systems, Inc.; Digby D. Macdonald, Pennsylvania State University

A review is presented of deterministic Monte Carlo simulation (DMCS) method for describing the development of localized corrosion damage. The main idea of this method is  to keep track of each stable pit (or crack) that nucleates, propagates, and repassivates on the metal surface. DMCS is “deterministic”, because the component models are explicitly constrained by the relevant natural laws and because the corrosion evolutionary path is specified.   A great advantage of this method lies in the fact that this approach allows us to take into account the interactions between particular individual pits (cracks) in an explicit manner.  By doing so, it becomes possible to reduce the number of unknown parameters that describe the interaction between individual pits (cracks).
