摘要
用单辊甩带法制备出了Ti60Zr10Ta15Si15和(Ti60Zr10Ta15Si15)96Sn4薄带,用X射线衍射仪(XRD)确定了这些薄带的非晶特征,使用示差扫描量热计(DSC)研究了其热力学行为,使用动电位测试仪研究了两种非晶薄带在PBS溶液中的动电位极化曲线.结果表明,Sn元素的添加,降低了Ti60Zr10Ta15Si15的热稳定性.在PBS溶液中,Sn元素的添加,导致非晶薄带的腐蚀电流密度减小,钝化电位降低,显著提高了抗腐蚀能力.
In this study, the Ti60Zr10Ta15Si15 and （Ti60Zr10Ta15Si15 ）96Sn4 ribbons were prepared by chill block melt-spinning, their amorphous property were identified by X-ray diffraction, their thermodynamic behavior were analyzed by differential scanning calorimeter（DSC）, and the effect of Sn addition on the cor- rosion behavior was investigated by using electrochemical techniques. The results show that, Sn addition in the Ti60Zr10Ta15Si15, decreases its thermal stability, and results on the decrease of corrosion current density and passive potential, improves the corrosion resistance in PBS solution.
