Micro-arc Oxidation Technique for Aluminum and its Alloys
DONG Qing1, CHEN Chuan-zhong1, WANG De-yun1, LEI Ting-quan1,2
Abstract:
Recent developments over these years on the surface treatment for aluminum and its alloys by micro-arc oxidation (MAO) were reviewed. The effects of the substrates and the electric parameters such as current density, voltage and frequency on the growth, composition, structure and properties of the MAO coatings on aluminum alloys were emphasized. The common electrolyte systems used in the MAO treatment for aluminum alloys were analyzed. The characteristics of kinetics and the growth mechanism of the MAO coatings on aluminum alloys were described. It was pointed out that the control of electric parameters and adjustment of composition and concentration of electrolyte would be the study emphases of MAO technique for aluminum alloys in the future.
Key words:  micro-arc oxidation  aluminum and its alloys  phase composition  properties  influence factor
