LOCALIZED CORROSION OF ALUMINIUM ALLOYS. A REVIEW

Localised corrosion, which usually appears as pitting, crevice corrosion, or certain aspects of stress corrosion cracking, is a multi-step process. This review considers the four steps involved in localised corrosion: (1) adsorption of the reactive anion on the oxide covered aluminium; (2) chemical reaction of the adsorbed anion with the aluminium ion in the aluminium oxide lattice or the precipitated aluminium hydroxide; (3) thinning of the oxide by dissolution; and (4) direct attack of the exposed metal by the anion, perhaps assisted by an anodic potential. The experimental work reported in the literature is evaluated within this framework.
