AbstractThe transient crevice corrosion behavior of 304 stainless steel in NaCl solution has been investigated by a multiphysics coupling model. The model considers local electrochemical reactions, transport of different species, and homogeneous reactions. The moving mesh method is used to obtain the geometrical change of the crevice wall with time due to corrosion. The level set method is employed to quantitatively describe the influence of the precipitation process on electrochemical reactions. The transient crevice corrosion morphology, potential and current distributions, and pH and chloride ion concentration distributions are obtained by simulation. The effect of crevice geometry factors on the corrosion process is also discussed. The simulation results are in good agreement with the experiments, showing that the model has high reliability.
