| 摘 要： | 采用光纤激光打标机在GH4169基底上刻蚀出微观结构,并通过在1.0%氟硅烷(FAS)乙醇溶液中改性降低表面能制备GH4169超疏水表面。该超疏水表面能达到接触角大于160°且滚动角小于10°。通过扫描电子显微镜(SEM)、能谱仪(EDS)、接触角测量仪对样品的微观结构、元素组成及润湿性进行表征和分析。采用单因素实验探究光纤激光打标机的扫描频率、功率以及速度对GH4169表面润湿性的影响规律,并对制备出的超疏水表面的粘附性和自清洁性进行了测试。

| Abstract: | A fiber laser marking machine has been used to etch the microstructure on the GH4169 substrate,and the GH4169 super-hydrophobic surface has been prepared by modifying the surface energy in 1.0%fluorosilane(FAS)ethanol solution to reduce the surface energy.The super-hydrophobic surface can reach a contact angle of more than 160°and a roll angle of less than 10°.The microstructure,elemental composition and wettability of the samples have been characterized and analyzed by scanning electron microscope(SEM),energy spectrometer(EDS),and contact angle measuring instrument.The influence of scanning frequency,power and speed of fiber laser marking machine on the wettability of GH4169 surface has been investigated by single-factor experiments,while the adhesion and self-clean ability of the prepared super-hydrophobic surface have been tested. |
