与纯激光照射相比，激光烧蚀与化学修饰相结合的复合制备技术是获得仿生超疏水表面的一种广泛应用的技术。然而，传统的表面化学修饰技术面临着微纳结构分离和超疏水表面不稳定性等挑战。本研究介绍了一种创新的方法，通过激光曝光、碳离子注入和氟烷基硅烷（FAS）改性相结合，在NiTi合金上产生极其稳定的超疏水表面。系统地研究了表面形貌和化学成分，揭示了超疏水性的形成机理。此外，还研究了这种超疏水表面的耐磨性、热稳定性和耐腐蚀性。并进一步揭示了相应的稳定性改善机制。
Comparing with pure laser irradiation, the hybrid fabrication using laser ablation and chemical modification is one of the widely used techniques to obtain bio-inspired super-hydrophobic surface. Nevertheless, conventional surface chemical modification techniques have faced challenges including the detachment of micro-nano structures and the instability of super-hydrophobic surfaces. This research introduces an innovative method for creating extremely stable super-hydrophobic surfaces on NiTi alloy through a combination of laser exposure, carbon ion implantation, and modification with fluoroalkylsilane (FAS). Surface morphology and chemical component were systematically investigated to reveal the formation mechanism of super-hydrophobicity. Besides, its abrasion stability, thermal stability and corrosion resistance stability of this kind of super-hydrophobic surface were also investigated. And the corresponding stability improvement mechanisms were further revealed.
