Pitting Corrosion and Surface Chemical Properties of a Thin Oxide Layer on Anodized Aluminum Alloys.

Abstract

Aluminum alloys, 2024 and 7075, containing copper were found to react readily with a mixture of methanol and carbon tetrachloride. A homogeneous oxide film covering these metals does not allow the solution to attack the alloy. Pitting corrosion occurs when the alloying constituents cause defect structures in the oxide film. Copper was detected in the pits of all the specimens studied. (Author)
