Simulation of the growth of oxide layer of stainless steels with chromium using cellular automaton model: Verification and parameter study

A cellular automaton (CA) model based on the stochastic approach was proposed to simulate the process of oxidation and corrosion of stainless steels with different contents of chromium in flowing lead bismuth eutectic (LBE). To verify the reliability of the thickness of the oxide layer simulated by CA model, the influence of the stochastic character on the simulating results was investigated as varying parameter of chromium content of structure material in this study. Ten independent simulations were tested and run for each specific environment. Convergent and reasonable results of simulation were obtained according to the chi-square of goodness-of-fit test and results of experiment.
