| 摘 要： | 对经过不同表面处理的钛镍合金丝材的力学性能进行了对比分析。研究表明：与酸洗及机械抛光相比，电解抛光可有效改善钛镍丝材的力学性能，而经电镀工艺处理后的试样则易发生氢脆现象，从而显著降低材料的力学性能指标。

Effect of Surface Processing on Tensile Properties of NiTi Wire |
| |
| Abstract: | The mechanical properties of the NiTi wire with different surface processing were investigated by means of tensile test It was found that compared with acid washed and mechanical polished samples, electropolished samples have better mechanical properties, while the electroplated sample tends to show worse mechanical properties owing to the hydrogen embrittlement |
