可降解血管支架用Mg-2Y-xZn-0.4Zr合金腐蚀性能的研究
Research on Corrosion Property of Mg-2Y-xZn-0.4Zr Alloys for Degradable Vascular Stent
摘要
Abstract
In order to improve the corrosion resistance of magnesium alloy,the corrosion performance of Mg-2Y-xZn-0.4Zr (x=0,1,2 and 4 wt.％) alloys in simulated human body solution (SBF solution) were studied by optical microscope,scanning electron microscope,X-ray diffraction and weight loss corrosion.The results show that the addition of Zn element makes the grain refinement,and the addition of 1％ Zn element into the alloy produce Mg3YZn6 phase,and the Mg3Y2Zn3 phase forms when the content of Zn increases to 2％,the corrosion resistance of the alloys increase firstly and then decrease.Mg-2Y-1Zn-0.4Zr alloy exhibits the best corrosion resistance in this study.关键词
