Abstract:
We examined the general phenomenology associated with the corrosion of Al Alloy 2024-T3. Copper redistribution is controlled by S-phase dealloying and matrix dealloying. Matrix dealloying of aluminum occurs owing to the increased pH that develops at the alloy/electrolyte interface owing to oxygen reduction. We summarize results of a detailed investigation aimed at determining the mechanism and magnitude of the oxygen diffusion limited current density during corrosion of Al Atloy 2024-T3. Our results show that oxygen reduction occurs via the standard 4-electron mechanism and that the oxygen diffusion - limited current density has a value of approx. 25 uA cm(-2).
