2021-6-4 For aluminum, pitting corrosion is most commonly produced by halide ions, of which chloride (Cl -) is the most frequently encountered in service. Pitting of aluminum in halide solutions open to the air occurs because, in the presence of oxygen, the metal is readily polarized to its pitting potential.
Corrosion of aluminum alloys in a substantial environment is due to the cathodic and anodic reactions co-occurring at the same rate on the metal surface.. The cathodic reaction is the oxidation process of the metal, and the anodic reaction is the reduction

查看次数 5,334What can cause aluminum to corrode? This contradictory nature is explainable because nascent aluminum reacts with oxygen or water and forms a coherent surface oxide which impedes further reaction of aluminum with the environment. Corrosion is the reaction of aluminum with water and the subsequent deterioration of its properties.
