| 摘 要： | 提出了一种快速制备具有超疏水性、耐磨性和耐腐蚀性的Ti-10V-2Fe-3Al （TB6）钛合金表面的方法。通过纳秒激光器对抛光的钛合金进行精确烧蚀，构筑了具有平行微沟槽阵列特征的织构表面。随后，利用紫外线灯照射和十八烷基三氯硅烷溶液浸渍进行化学改性，进一步增强了表面的疏水性。从表面形态和化学组分的角度分析了微沟槽间隔对织构表面润湿性的影响。结果表明，在干滑动、水润滑和油润滑条件下，所制备的超疏水表面相较于原始亲水表面，平均摩擦系数分别降低了34%、56%和59%。此外，分析了相关摩擦系数变化的机理。通过动电位极化测试验证，所制备的超疏水表面展现出优异的耐腐蚀性，为钛合金基体提供了有效的长期保护。

| Abstract: | We proposed an efficient method to fabricate superhydrophobic, wear and corrosion resistant groove-textured surfaces based on TB6 (Ti-10V-2Fe-3Al) titanium alloy substrates. The smooth surface of the titanium alloy was ablated using a nanosecond laser to create a surface with a parallel groove pattern. In order to further improve the surface hydrophobicity, the laser treated surface was irradiated by an ultraviolet lamp for 1 h and subsequently immersed in a 3wt% octadecyltrichlorosilane solution for 2 h for chemical modification. The wettability of the groove-textured surfaces with varying groove spacing was investigated by analyzing surface morphology and chemical composition. Results show that the average coefficient of friction (COF) of the superhydrophobic surface is reduced by 34%, 56%, and 59% compared with that of the original hydrophilic surface under dry, water, and oil lubrication conditions, respectively. The mechanism variation of the CoF was also discussed. Potentiokinetic polarization testing demonstrates that the prepared superhydrophobic surface provides corrosion protection for the titanium alloy substrate. |
