摘要:
超疏水表面具有自清洁功能，而具有高表面能的普通彩色不锈钢表面易被污染，针对该缺点，对不锈钢表面进行超疏水改性可予以克服。因此，本文首先在无铬的硫酸电解质溶液中采用方波电流极化对 304 不锈钢进行前处理，获得微粗糙表面结构，再切换为方波电位极化模式，于相同的硫酸介质中进行着色处理，最后由氟硅烷自组装修饰彩色表面。采用水接触角测量、扫描电子显微镜、电化学交流阻抗谱等方法对表面进行了微观结构及性能的表征，研究了方波电流蚀刻参数以及方波电位着色参数对氟化表面水浸润性能的影响，并在优化参数下制备得到 接触角大于 150 ° ，且耐腐蚀性能优于普通彩色不锈钢的超疏水彩色不锈钢表面。本方法中采用的着色液无铬，且蚀刻液与着色液成分相同，两者合二为一，减少了废液处理成本，具有较好的应用前景。
Abstract:
： The superhydrophobic surface has the function of self-cleaning ， so superhydrophobic modification of the ordinary color stainless steel surface which has high surface energy can overcome the disadvantage that it is easily contaminated. Therefore ， in this paper ， 304 stainless steel was pretreated by square wave current polarization in chromium free sulfuric acid electrolyte to obtain micro rough surface structure ， then colored in the same sulfuric acid medium under square wave potential polarization mode ， and finally decorated with fluorosilane. The surface microstructure and properties were characterized by water contact angle measurement ， scanning electron microscope and electrochemical impedance spectroscopy. The influences of square wave current etching parameters and square wave potential coloring parameters on the water wettability of fluorinated surface were investigated. The superhydrophobic color stainless steel surface with contact angle greater than 150 ° and corrosion resistance better than ordinary color stainless steel was succesfully prepared under the optimized parameters.The coloring solution used in the method has no chromium ， and the components of the etching solution and the color ing solution are the same. The two are combined into one ， which reduces the waste liquid treatment cost. The proposed process has a good application prospect.
