WebJan 1, 2011 · Corrosion of aluminium is an electrochemical process that involves the dissolution of metal atoms. It only occurs once the oxide film has been dissolved or damaged. Aluminium is amphoteric in nature, its oxide film being stable in neutral conditions, but soluble in acidic and alkaline environments. WebJan 1, 2007 · Cathodic (or more correctly anodic) protection is an effective way of preventing pitting corrosion of aluminum alloys [ 23 ]. The other issue is the requirement for very low current relative to the cathodic protection of steel.
Webthe corrosion protection afforded aluminum (Al) alloys, by this method, and to compare them to the cor- rosion protection by sulfuric acid anodizing. Both electrochemical impedance spectroscopy (EIS), an alternating current (ac) method, and the direct current (dc) polarization resistance (PR) method were employed in this investigation. WebMar 30, 2024 · Metals and alloys are essential in modern society, and are used in our daily activities. However, they are prone to corrosion, with the conversion of the metal/alloy to its more thermodynamically-favored oxide/hydroxide phase. These undesirable corrosion reactions can lead to the failure of metallic components. Consequently, corrosion …
