Boundary Element Method Simulation for the Variation of Electrochemical Property of Aluminium Alloy due to Applied Stress

Abstract

When the oxide film is damaged by stress, the electrochemical properties change and the material may corrode. The polarization curve of the aluminum alloy under stress loading in the NaCl solution was measured and the boundary element electric field analysis of the damaged surface was carried out. From this analysis, the electrochemical properties of the new surface exposed from the damaged oxide film were identified.
