分别通过浸泡试验、菌落计数法和抗菌粘附力研究了Mg-4Zn-xSn合金(x=0、1.0、1.5wt%)的放氢行为和抗菌性能。结果表明，由于表面膜中含有Sn，含Sn的Mg-4Zn合金比Mg-4Zn合金具有更低的氢释放量和更好的对金黄色葡萄球菌（S. aureus）的抗菌性能。从合金中降解的Zn2+和Sn2+/Sn4+离子是其高抗菌效果的主要原因。它提供了一种有效的材料设计方法，以解决目前可生物降解镁合金的缺点。 (C) 2019 Elsevier B.V. 保留所有权利。
Hydrogen release behavior and antibacterial property of Mg-4Zn-xSn alloys (x = 0, 1.0, 1.5 wt%) were investigated by immersion tests, colony counting method and antibacterial adhesion, respectively. Results show that Sn-contained Mg-4Zn alloys have lower hydrogen release and better antibacterial property to Staphylococcus aureus (S. aureus) than that of Mg-4Zn alloy, for Sn incorporated in the surface film. Zn2+ and Sn2+/Sn4+ ions degraded from the alloys are the main cause for the high antibacterial effect. It provides an effective way to design materials to solve current shortcomings of biodegradable Mg alloys. (C) 2019 Elsevier B.V. All rights reserved.
