| 摘要: |
| 探索使用1064 nm准连续激光清洗TA15钛合金表面氧化层，验证了激光清洗TA15表面氧化层的可行性，使用SEM、XPS及三维形貌仪等仪器，分析了激光功率、离焦量、清洗速度等热输入量相关工艺参数变化对激光清洗表面质量的影响，并通过表面组分测试，分析了激光清洗TA15表面氧化层的效果。结果表明，TA15钛合金粗糙度随着激光功率的增大而降低、随着离焦量的增大而增大，而清洗速度的提高会导致粗糙度先降低后增加；激光清洗TA15最优工艺参数为功率400 W、离焦量0 mm、清洗速度5 mm/s，清洗后表面形貌良好，粗糙度Ra约为0.18 μm。使用最优工艺获得的清洗件经XPS图谱分析，其激光清洗前钛合金表面成分为主要TiO2，激光清洗后表面成分为Ti，受到清洗残渣干扰，存在微量Ti=O键。 |

| Abstract: |
| The 1064 nm quasi continuous laser cleaning of surface oxide layer on TA15 titanium alloy was explored, and the feasibility of laser cleaning of TA15 surface oxide layer was verified. The influence of process parameters related to laser power, defocusing amount, cleaning speed on laser cleaning surface quality was analyzed using SEM, XPS and three-dimensional morphology observation instrument. The surface component test was used to analyze the quality of laser cleaning. Results show that the roughness of TA15 titanium alloy decreases with increasing of the laser power, and increases with increasing of the defocusing amount, while increasing of the cleaning speed will cause the roughness to decrease first and then increase. The optimal process parameters of laser cleaning TA15 are power of 400 W, defocusing amount of 0 mm and cleaning speed of 5 mm/s. After cleaning, the surface morphology is good, and the roughness Ra is about 0.18 μm. After XPS analysis of the cleaning parts obtained by the optimal process, TiO2 was found as the main composition on the surface of titanium alloy before laser cleaning, and the main surface composition after laser cleaning is Ti, with micro Ti=O resulted from the cleaning residue. |
