In this study, in order to increase surface ability of hardness and corrosion of magnesium alloy, anodizingand sealing with nano-diamond powder was conducted. A porous oxide layer on the magnesium alloy was successfullymade at 85℃ through anodizing. It was found to be significantly more difficult to make a porous oxide layer in themagnesium alloy compared to an aluminum alloy. The oxide layer made below 73℃ by anodizing had no porous layer.The electrolyte used in this study is DOW 17 solution. The surface morphology of the magnesium oxide layer wasinvestigated by a scanning electron microscope. The pores made by anodizing were sealed by water and aqueous nano-diamond powder respectively. The hardness and corrosion resistance of the magnesium alloy was increased by the anod-izing and sealing treatment with nano-diamond powder.
