Abstract:
Magnesium alloys have attracted increasing attention as new biodegradable metal materials and have been widely researched in recent years. The development of magnesium alloys has been reviewed from four aspects: engineering Mg alloy, newly designed Mg alloy, surface modified Mg alloy, and Mg alloy with novel structure. The investigated results in alloy design, mechanical property, corrosion property, cytotoxicity, and animal test have been systematically introduced and summarized. Finally, the unsolved scientific problems of biodegradable magnesium alloys and their possible applications are proposed.
