| 目的 针对焊前去除TiNi合金表面致密氧化膜过程中，传统方法会造成环境污染的问题，运用激光清洗这一绿色清洗方法去除TiNi形状记忆合金表面轧制氧化膜，并对其清洗工艺进行研究。方法 运用OM和XRD等分析测试手段对激光清洗后TiNi合金表面进行测试，研究激光清洗工艺对TiNi合金表面氧化膜及其组织的影响。结果 激光清洗参数对激光清洗效率影响较大，扫描次数对TiNi合金激光清洗效率具有饱和性；激光清洗过后的TiNi合金表面仍存在一定含量的TiO, TiO2, Ti3O5等氧化物。结论 激光清洗可得到表面明亮且均匀的TiNi合金，但不能完全清除TiNi合金表面氧化膜。 |

| In allusion to the problem that the traditional method for removing the dense oxide film on the surface of TiNi shape memory alloy might cause environmental pollution, the paper aims to remove the dense oxide film on the surface of TiNi shape memory alloy through laser cleaning and research the cleaning method. The surface of TiNi alloy after laser cleaning was tested by OM, XRD and other analytical testing methods to research effects of laser cleaning process on the oxide film and its microstructure on TiNi alloy surface. Parameters of laser cleaning had great effects on the cleaning efficiency. The scanning times had saturation to the laser cleaning efficiency of TiNi alloy. There was still a certain amount of TiO, TiO2 on the surface of TiNi alloy after laser cleaning. TiNi of bright and uniform surface might be obtained by laser cleaning, but laser cleaning cannot completely remove the oxide film on TiNi alloy surface. |
