Adhesion Phenomenon of Titanium as Cathode in Aluminum Anodizing

Abstract

This paper discusses the film coating formation mechanism after an anodizing process carried out in AA6061 with a varying potential between 15-30V. The electrolyte used to be 1M H3PO4with titanium as the cathode. From this study, it was found that after the anodizing process the pore uniformity occurs with a size varied from 1.09-5.74 μm become 2.78-4.56 μm. There was also an increase in the titanium content on the deposition surface about 21% and was achieved at an electric potential of 25V where titanium in the pore penetration occurs up to the depth of 5 μm.
