Abstract
A mathematical model has been developed to characterize mass transport and electrochemical conditions within a corrosion fatigue crack in steel immersed in seawater. The focus is on the concentration of H+ ions, which correlates with the rate of anodic dissolution. The Nernst-Planck equation, governing mass transport in the aqueous environment, is formulated and solved using COMSOL Multiphysics. The model accounts for crack face movements, which pump the corrosive medium in and out, facilitating species advection. This study investigates the effects of crack length and loading ratio, showing that longer cracks and higher R ratios lead to increased H+ concentration.
