| 中文摘要: |
| 通过铜模铸造法和熔融纺丝技术合成了具有生物医学应用性能的可生物降解Mg-Zn-Y非晶合金（MGs）。在体外研究了钇（Y）含量对Mg基非晶合金的形成、热稳定性、硬度、耐腐蚀性和细胞相容性的影响。通过细胞毒性测试（MTT）、凋亡测试和细胞骨架染色测定的结果发现，Mg-Zn-Y非晶合金具有良好的生物相容性，可以作为可生物降解材料。 |
| 英文摘要: |
| For the purpose of developing biodegradable magnesium alloys with suitable properties for biomedical applications,Mg-Zn-Y metallic glasses(MGs) were synthesized by copper-mold casting and melt spinning.The effects of Y addition on the glass formation,thermal stability,hardness,corrosion resistance,and cytocompatibility of the Mg-based glassy alloys were studied in vitro.The corrosion resistance and the biocompatibility are influenced by the percentage of Y element in alloy.In vitro cell culture study confirms that Mg-Zn-Y MGs have good biocompatibility determined by MTT,live-dead,and cytoskeleton staining assays,respectively.Thus,Mg-Zn-Y MGs possess the potential to be employed as biodegradable materials. |
