Numerical Simulation Based on a ZrO₂-Coated Stainless-Steel Corrosion Experiment

In this work, ZrO₂-coated on the surface of 304 stainless steel was prepared by a sol-gel method to study the corrosion resistance. Based on the experimental results, an effective numerical model was established using a finite element method to simulate the electrochemical corrosion of ZrO₂-coated stainless steel in a 5% NaCl solution. This model simulates the changes in electrode/electrolyte potential, ion concentration, and oxygen concentration during the polarization process and provides a relatively reasonable explanation for the influence of the density of ZrO₂ on the corrosion resistance of stainless steel.
