| Summary: | As a biodegradable material,magnesium alloys has been attracted by more researchers, recently. Due to good biocompatibility, mechanical properties and biodegradable absorption charac-teristics, it has been honored as revolutionary biological materials. However, current bio-magnesium alloy still could not meet the requirements of clinical application, due to its shortcomings of rapid corrosion rate and local corrosion. In this paper, the progress of bio-magnesium alloy in improving the corrosion performance was reviewed from the aspects of high purity, alloying, heat treatment process and surface modification. The paper makes a prospect on how to develop the biodegradable materials with better corrosion performance in terms of adding non-toxic alloying elements, proper surface coating, advanced preparation technology and heat treatment process. |
