摘　　要：为了研究Ca的含量对MgZnMnCa四元生物镁合金的组织和性能的影响,制备了Mg2Zn(0.2)MnxCa(x=0.1,0.4,0.7)合金,比较不同Ca含量的Mg2Zn(0.2)MnxCa的组织和腐蚀性能。结果表明,Mg2Zn(0.2)Mn(0.4)Ca合金的显微组织较好,平均晶粒尺寸约为100μm,第二相含量适中;Mg2Zn(0.2)Mn(0.4)Ca的镁合金耐腐蚀性较好,腐蚀速率为0.569mm/a。In this paper, the Mg2Zn0. 2MnxCa（x= 0. 1,0. 4,0. 7）quaternary biomedical magnesium alloy was prepared. And the effect of amounts of calcium on the microstructure and corrosion properties of Mg2Zn0. 2MnxCa was investigated. The results showed that the microstructure of Mg2Zn0. 2Mn0. 7Ca alloy has been significantly refined, their average grain size was about 100μm.The Mg2Zn0. 2Mn0. 4Ca alloy behavior better corrosion resistance property and its corrosion rate was 0. 569 mm/a.
