通过单辊甩带法制备了Ti40Cu39Zr10Ni11-xSnx(x=0,3,7,11)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=0,3,7,11)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。
Ti40Cu39Zr10Ni11-xSnx (x = 0, 3, 7, 11) amorphous ribbons were prepared by a single roll rejection method. The microstructures and properties of the alloys were characterized by X-ray diffraction (XRD), differential scanning calorimeter (DSC), electrochemical workstation and scanning electron microscope (SEM). The effects of Sn substitution on the thermal stability and Effect of biological corrosion resistance. The results show that with the addition of Sn, the Ti40Cu39Zr10Ni11-xSnx (x = 0, 3, 7, 11) alloy samples all show completely amorphous structure. Compared with Ti40Cu39Zr10Ni11 amorphous alloy, Ti40Cu39Zr10Sn11 amorphous alloy slightly improved the thermal stability, and bio-corrosion resistance has been significantly improved. Therefore, non-Be, Ni and other harmful elements on the human body Ti40Cu39Zr10Sn11 amorphous alloy has the potential as a biomedical material.
