Surface Studies of Anodic Aluminum Oxide Layers Formed in Phosphoric Acid Solutions.

Abstract

Phosphoric acid generates a composite oxide with a dense, nonporous layer forming on the aluminum anode, and then a porous layer forming on top. The nonporous layer forms a continuous film and should offer the most protection to the bulk metal. Our objective in this study was to determine the properties and growth characteristics of this nonporous layer under the influence of voltage and concentration of electrolyte. (Author)
