Microstructure and corrosion properties of Mg-Zn-Ca-Zr alloy for biomedical application

摘要：

　　The microstructures and corrosion properties of the as-cast Mg-Zn-Ca-Zr alloys were investigated in this study.The results showed that the alloy was mainly composed of α-Mg solid solution,Zr particle and the secondary phase of Ca2Mg6Zn3.The grain size of alloy specimens decreased with the increment of Zr content.The corrosion resistances were found to increase from 0.3% to 0.5% and then decrease from 0.5% to 0.7%.The Mg-4Zn-0.5Ca-0.5Zr had the best corrosion resistance in SBF solution.This was attributed to a combination of (1) the uniform and fine microstructure of alloy,(2) continuous distributions of the secondary phases,and (3) a lower volume fraction of Zr particles.
