Corrosion Behavior of Aluminum alloy AD31 in the Presence of Potassium Permanganate in an Acidic Media

摘要

The chronoamperometry method was used to study corrosion of the aluminum alloy AD31 in the presence of potassium permanganate in chloride-containing acidic media. A rotating disk electrode was used to establish the kinetic features, and the mechanisms of cathodic oxygen reduction on AD31 in permanganate-containing acidic solutions were proposed.
