An Electrochemically Sealed Al₂O₃ Passivation Layer for Aluminum Alloys

Abstract

An anodization process combined with an electrochemical sealing technique provided dramatic improvement in the corrosion resistance of 5086 Al alloy. The surface quality of the oxide depends on the density and distribution of alloying elements and impurities. © 1982, The Electrochemical Society, Inc. All rights reserved.
