    摘要:

    提出了一種快速制備具有超疏水性、耐磨性和耐腐蝕性的Ti-10V-2Fe-3Al （TB6）鈦合金表面的方法。通過納秒激光器對拋光的鈦合金進行精確燒蝕，構(gòu)筑了具有平行微溝槽陣列特征的織構(gòu)表面。隨后，利用紫外線燈照射和十八烷基三氯硅烷溶液浸漬進行化學(xué)改性，進一步增強了表面的疏水性。從表面形態(tài)和化學(xué)組分的角度分析了微溝槽間隔對織構(gòu)表面潤濕性的影響。結(jié)果表明，在干滑動、水潤滑和油潤滑條件下，所制備的超疏水表面相較于原始親水表面，平均摩擦系數(shù)分別降低了34%、56%和59%。此外，分析了相關(guān)摩擦系數(shù)變化的機理。通過動電位極化測試驗證，所制備的超疏水表面展現(xiàn)出優(yōu)異的耐腐蝕性，為鈦合金基體提供了有效的長期保護。

    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.
