报告内容：

Mg alloys have great potential in application in the medical field where Mg alloys may be used as a biodegradable material. The biocompatibility of Mg was first known in the early twentieth century. However, the intrinsic hydrogen evolution phenomena associated with Mg forced researchers to give up the first clinical trials. understanding of corrosion mechanisms and development of innovative corrosion protection techniques are interest in biodegradable Mg alloys. The factors influencing Mg corrosion in vitro are reviewed: (i) inorganic concentrations, (ii) organic components, and (iii) experiment parameters. This fundamental understanding likely corrosion behavior in vivo, and provides a basis for the standardization of Mg bio-corrosion testing.

In addition, the metallurgical factors of importance to the corrosion of Mg alloys will be explained, and suggestions provided for research directions.
