Corrosion of Mg for biomedical applications

This chapter reviews our understanding of Mg corrosion and the measurement of Mg corrosion. There is some emphasis on the use of Mg alloys for biodegradable medical applications. Mg melt purification using Zr has been shown to provide the opportunity to produce ultra-high-purity Mg alloys, which could lead to stainless Mg. Nors solution may be a good start model for the study of Mg for biodegradable medical implant applications. The uni-positive Mg+ corrosion mechanism is consistent with the know corrosion data, although it is clear that self-corrosion is also important.
