Abstract A mathematical analysis is proposed for the corrosion crevice in which polarization field, crevice geometry, surface condition,electrochemical kinetics, solution property and applied stress are represented by polarization potential and current, equivalent resistance, change of specific resistance and surface impedance respectively. The resulting differential equations are analysed and solved, from which mathematical models for several cases are obtained.■ These models have been evaluated by related experimental measurements with good agreement. With these models,potential at any point within the crevice can be calculated according to the potential outside the crevice.
