Abstract:

Anodizing process is an effective method to improve the surface properties of magnesium alloys. By now, much progress, including the optimization of electrolyte compositions, the selection of electric parameters, the film formation mechanism, the film structure and the post treatment, have been obtained based the traditional process, such as Dow 17 and HAE. In this paper, the details are reviewed and the trend of development is indicated.

Key words:magnesium alloy; anodization; electrolytic solution
