Abstract

There are many techniques to deposit alumina film; most of these methods required special environment such as electrochemical deposition or complicated apparatus such as plasma spraying. In the present paper, anodizing of AZ31 in NaOH solution with co-precipitation of nano-size alumina particles was investigated to produce alumina-rich surface film on AZ31 magnesium alloy. The corrosion resistance was studied by potentiodynamic polarization technique; the corrosion resistance of AZ31 magnesium alloy was significantly improved by anodizing.
