| 摘 要： | 目的利用化学刻蚀、化学氧化方法在304不锈钢表面制备微纳米结构并实现超亲水性质,改变时效处理温度,研究亲水表面润湿性的稳定程度。方法以2 mol/L的FeCl_3溶液、HCl、H_2O_2按照15:1:1的体积比混合得到刻蚀溶液,氧化液采用CrO_3与H_2SO_4的混合溶液。刻蚀完成后,通过接触角测量仪(OCA15EC)、场发射扫描电子显微镜(FE-SEM)及自带的能谱仪(EDS)表征试样表面的接触角、微纳米级表面形貌及试样表面元素,并分析不同处理条件下润湿性的变化规律。结果在本征润湿角为45°左右的304不锈钢基体上,通过化学刻蚀、化学氧化的复合处理方法可以获得超亲水表面。常温条件下,试样能够维持一定时间的超亲水性质。高温时效处理后,超亲水表面的润湿性发生变化,经400℃时效处理后,重新获得超亲水特性。结论该方法较易在耐腐蚀基体不锈钢表面制备微纳米结构,对基体表面润湿性产生影响。

| Abstract: | The work aims to study stability of hydrophilic surface wettability as a function of aging temperature by prepar-ing micro-nano structures and realizing super-hydrophilicity on the surface of 304 stainless steel by chemical etching and chem-ical oxidation. An etching solution was obtained by mixing 2 mol/L FeCl3solution, HCl and H2O2in a volume ratio of 15:1:1. Contact angle, micro-nano surface morphology and surface elements of the sample were characterized with contact angle mea-suring instrument, field emission scanning electron microscope and self-contained energy dispersive spectrometer, and change rule of wettability in different treatment conditions was analyzed. The super-hydrophilic surface could be obtained by chemical etching and chemical oxidation on the 304 stainless steel substrate with intrinsic wetting angle of 45°. Super-hydrophilicity of the sample could be maintained for a certain period of time at normal temperature. Wettability of the super-hydrophilic surface changed after aging treatment at high temperature, and the super-hydrophilicity was recovered after aging treatment at 400 . ℃The method facilitates preparation of micro-nanostructure on stainless steel surface of corrosion resistant substrate, and has ef-fects on wettability of substrate surface. |
