摘要

通过单辊甩带法制备了Ti40Cu39Zr10Ni11-xSnx（x=0

11）非晶薄带。运用X射线衍射仪（XRD）、差示扫描量热仪（DSC）、电化学工作站、扫描电镜（SEM）等手段测试了合金的组织与性能特性

研究了Sn替换Ni对合金热稳定性及生物耐蚀性能的影响。结果表明

随着Sn的添加

Ti40Cu39Zr10Ni11-xSnx（x=0

11）合金试样均表现为完全的非晶结构。与Ti40Cu39Zr10Ni11非晶合金相比

Ti40Cu39Zr10Sn11非晶合金的热稳定性稍有改善

且生物耐蚀性能得到明显提高。因此

不含Be、Ni等对人体有害元素的Ti40Cu39Zr10Sn11非晶合金具有作为生物医用材料的潜力。

Abstract

In order to develop a Ni-low or Ni-free Ti-based metallic glass for biomedical application

Ti40Cu39Zr10Ni11-xSnx（x=0

atom fraction

%）metallic glass ribbons were prepared by melt-spinning method.The amorphous characteristics and thermodynamic performance of the metal glass were investigated by X-ray diffraction（XRD）and differential scanning calorimeter（DSC）.The bio-corrosion resistance of the metallic glass was evaluated by electrochemical workstation phosphate buffered saline（PBS）at 37℃.The corrosion morphology was observed by scanning electron microscopy（SEM）.Effects of Sn substituted for Ni on the thermal stability and bio-corrosion resistance were described.The results show that with Sn addition

Ti40Cu39Zr10Ni11-xSnx（x=0

11）alloy exhibits amorphous structure

and the thermal stability of Ti40Cu39Zr10Sn11 can be improved slightly compared with that of Ti40Cu39Zr10Ni11

however

the bio-corrosion resistance is improved obviously.Ti40Cu39Zr10Sn11 metallic glass can be used as potential biological medical material.
