Research Progress on Corrosion Resistance of Medical Magnesium Alloy

In recent years, medical magnesium alloy, as "the third-generation biomedical material", has attracted the attention of many scholars due to its excellent biocompatibility and degradability, and has demonstrated its unique potential in the context of the difficulty of degradation of traditional medical implants. However, due to its poor corrosion resistance, it is difficult to meet the needs of clinical applications of medical implants, so the study of the corrosion resistance of medical magnesium alloys has a pivotal role. In this paper, based on the corrosion resistance of three typical medical magnesium alloys, the latest research progress of the corrosion resistance of medical magnesium alloys with different elemental contents in clinical applications and the corrosion protection technologies such as surface coating and alloying was reviewed, and the results of the application of computer simulation technology in the corrosion study of medical magnesium alloys were introduced. Accordingly, the future development trend of the medical magnesium alloys materials was prospected.
