... and investigation of factors affecting it. Magnesium–aluminum–zinc alloys (AZ grades) have been developed for use as biodegradation materials because the addition of aluminum and zinc as alloying elements can ameliorate their mechanical properties and increase corrosion resistance over those of pure magnesium alone...

...Karin Beaussant Törne, PhD; Fareed Ashraf Khan, PhD; Andreas Örnberg, Lic, MSc; Jonas Weissenrieder, PhD Zinc (Zn) alloys form a promising new class of biodegradable metals that combine suitable mechanical properties with the favorable degradation properties of pure zinc. However, the current...

... as biodegradable implant material. Due to its mechanical and biological characteristics, magnesium is highly suitable as a degradable implant material. It is non-toxic and biocompatible because the magnesium ions (Mg^{2+) which arise during the corrosion process are absorbed by the surrounding body tissue}...

...Adam J. Drelich; Patrick K. Bowen, PhD; Leslie LaLonde, BS; Jeremy Goldman, PhD; Jaroslaw W. Drelich, PhD A better understanding of the surface oxide film on biodegradable metals could lead to the design of smarter, surface-responsive biodegradable stents with good biocompatibility and controlled...
