| 目的 降低金属钛表面的反射率，探索钛表面黑化处理的新工艺。方法 采用飞秒激光技术对金属钛表面进行了黑化处理，通过研究激光功率、扫描速度、重复频率等工艺参数，研究不同试验状态下样品的表面形貌和反射率，采用扫描电镜表征样品的微观结构，同时利用分光光度计测试样品的反射率曲线。结果 当激光功率为6 W、扫描速度为100 mm/s、重复频率为200 kHz时，样品的反射率最低，在250~800 nm波长范围内的平均反射率为2.66%。结论 调节激光参数可以在金属钛表面获得不同形貌的微结构，不同工艺参数下获得的样品的反射率不同，但是都可以降低钛表面的反射率。 |

| The work aims to reduce the reflectance on the surface of titanium and explore a new titanium surface blackening process. The surface of titanium metal was blackened by femtosecond laser technology. The surface morphology and reflectivity of the samples under different experimental conditions were studied by changing the parameters like laser power, scanning speed and the repetition rate. The microstructure of the sample was characterized by scanning electron microscopy and the reflectance curve of the sample was measured by spectrophotometer. The reflectivity of the sample reached the lowest when the laser power was 6 W, the scanning speed was 100 mm/s and the repetition rate was 200 kHz. The average reflectance was 2.66% in the wavelength range of 250 nm to 800 nm. The microstructures of different morphologies on the metal surface of titanium can be obtained by changing laser parameters. The reflectivity of the samples obtained under different process parameters is different, but both can reduce the reflectivity of the titanium surface. |
