Corrosion Simulation Technology Based on Electrolyte Thermodynamics

Abstract

Corrosion behavior of materials in aqueous solution can be quantitatively analyzed by simulation with electrolyte thermodynamic model, electrochemical kinetic model on material surface and mass-transfer and adsorption models between solution and material surface. This report introduces thermodynamic analysis method by real solution stability diagram, general corrosion rate estimation method by simulated polarization curves and localized corrosion susceptibility evaluation method by repassivation potential with concrete validation examples.
