In this paper, a two-dimensional cellular automata (CA) method is used to simulate the corrosion behavior of Fe-Cr-Ni alloy in NaCl-CaCl2 molten salt. Simulation results and experimental measurements show good agreement, revealing the detailed change and migration of components in the corrosion process of Fe-Cr-Ni alloy in molten chloride salt over time. The simulation revealed that the grain size, elemental composition of the alloy, and O-2 and H2O contents in the molten salt are important factors that significantly affect the cormsivity of the NaCl-CaCl2 molten salt with respect to the Fe-Cr-Ni alloy. Additionally, the CA method shortens the period of experimental research and the progression of corrosion is predicted.
