In this study, we performed a pitting corrosion simulation that considers the cathode environment, specifically pH and the diffusion-limited current density. First, the cathode polarization curve was modeled based on the Butler-Volmer and Nernst equations. Next, using a zooming method, the results from a global domain electric field analysis that incorporated the modeled cathode curve were used to conduct a local analysis of pitting corrosion propagation.
