| 中文摘要: |
| 目的 解决普通彩色不锈钢表面能高、易被污染的缺点，制备既有装饰效果又具有超疏水自清洁性能的彩色超疏水不锈钢表面。方法 通过简单的化学蚀刻法在不锈钢表面建立微纳米尺度的二元微结构，在此基础上进一步由铬酸化学氧化法（INCO法）在不锈钢表面生成微纳米结构彩色膜，经全氟硅烷分子修饰后，最终获得低表面能类荷叶粗糙结构。通过着色曲线、扫描电镜、电子能谱分析仪以及接触角测试等手段研究了化学蚀刻前处理对不锈钢着色性能、微观结构、表面浸润性以及耐腐蚀性能的影响。结果 蚀刻处理后，着色过程减缓，所着终点颜色有轻微改变，着色后表面保留了微纳米粗糙结构。由全氟硅烷分子修饰后，获得超疏水彩色不锈钢表面，水接触角为152.6°，其耐腐蚀性能较普通彩色不锈钢更为优异。结论 成功制备了耐蚀彩色超疏水不锈钢表面。 |

| The work aims to overcome disadvantages of ordinary colored stainless steel surface, i.e., high surface energy and easily being contaminated by preparing super-hydrophobic colored surface on the stainless steel matrix. Micro/nano multi-scale dual microstructure was established on stainless steel surface in a simple method of chemical etching, on this basis, a micro/nano structured colored film was further established on the surface in the method of chromic acid oxidation (INCO method). Finally, after being modified with perfluorinated silane, a rough surface similar to lotus leaf surface of low surface energy was obtained. Effects of chemical etching pretreatment on coloring performance, microstructure, surface wettability and corrosion resistance of the stainless steel surface were studied with coloring potential-coloring time curves, scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), and contact angle tester. The chemical etching treatment could slow down coloring rate, and made end color changed slightly. After being colored, the surface retained the micro/nano structure. After modification with perfluorinated silane molecules, a super hydrophobic colored stainless steel surface with water contact angle of 152.6° was ob-tained, which showed better corrosion resistance than the ordinary colored stainless steel surface. In conclusion, the su-per-hydrophobic colored stainless steel surface is successfully prepared. |
