The corrosion-and wear-resistant coatings on 7075-T6 aluminum alloy were prepared using micro-plasma oxidation in aqueous electrolytic solution with different amounts of solid MoS 2 powder of 2μm. The bipolar rectangular pulse with a frequency of 1000Hz potentiostatically and galvanostatically is used in this work. The results indicate that the corrosion resistance and wear resistance can be further improved by the addition of MoS 2 powders in solution. The optimal amount of solid MoS 2 powder in electrolytic solution (2g/L) will substantially enhance the corrosion resistance, increase the hardness of MAO coatings and improve the wear resistance, irrespective of potentiostatic and galvanostatic power supply.
