| 摘 要： | 用AES和XPS研究了NiTi合金表面氧化膜的成分和结构.结果表明,NiTi合金表面主要元素有C、O、Ti、Ni等;氧化膜的最外层由TiO2和TiO及少量的Ni组成,TiO和TiO2的相对含量分别为 30.32%,69.68%;表面氧化膜下存在一层富Ni层.随表面距离的增加,TiO2和TiO的含量逐渐减少,Ti的含量增加,而Ni一直没有价态的变化.

| Abstract: | The component and microstructure of the oxide film on the surface of NiTi alloy was researched by means of AES and XPS. The results show that, the NiTi alloy surface layer consists of C,O,Ti and Ni and so on; the outer layer of the oxide film consists of TiO 2, TiO and a little Ni; the relative contents of TiO and TiO 2 are 30.32% and 69.68%, respectively; a Ni-rich layer exists under the surface oxide film; the content of TiO 2 and TiO decreases gradually but that of Ti increase as the deep of the oxide film incrases; Ni didn't change in valence. |
