N2 - Biomedical applications of magnesium alloys have attracted increasing attention due to their unique combination of advantages. However, the poor corrosion resistance is an obstacle to magnesium alloys being used as biodegradable materials. As zinc (Zn) and calcium (Ca) are non-toxic and recognized as nutritionally essential elements in the human body, in this study Zn and Ca were selected as alloying elements to produce suitable bio-corrosion properties. The grain size was reduced significantly from 141.4 μm to 97.3 μm by adding Ca.
