Growth of anodic Aluminum Oxide using titanium as cathode – a review

Abstract

Aluminum is a material with a variety of uses in various fields because this material is easy to obtain, can be made in various ways and has good corrosion resistance. Now this material begins to be studied and applied to the realm of biomaterials, with the use of the membrane of the aluminum oxide layer on the body of living things began to be applied. In this paper further elaborated on the use of titanium alloys as cathodes in the aluminum anodizing process. Deep discussion is emphasized on the growth process of the oxide layer that occurs during the anodizing process, where the oxide layer consists of a barrier layer and a pore layer. During the process, not only does the oxide layer grow with time but also the appearance of voids in the pore lining wall. In the final result, it was found that titanium was able to penetrate the oxide layer formed during the anodizing process. As for future applications, it is expected that the anodizing material is expected to be an alternative material in the field of biomaterial replacement
