Abstract:Micro/nano rough structure which is needed for super hydrophobic is processed on the surface of aluminum by electrochemical etching firstly. Then oxide layer is formed on the surface of micro/nano rough structure by dc anodic oxidation ,and it is electrolytic colored in a mixture of potassium permanganate and sulfuric acid solution. Lastly ,the color aluminum super hydrophobic surface is prepared by reducing the surface energy with the silane modified fluorine. The as-prepared surface were characterized to get the microstructure ,chemical composition and wettability. The results show that the color on the aluminum surface is darker with general super hydrophobic ,and contact angle between water droplets and surface achieves to 153.1° ,while rolling angle is 1° when electrochemical machining time is 4 min. The color on the aluminum surface is tan with better super hydrophobic,and contact angle between water droplets and surface achieves to 157.2° ,while rolling angle is 1° when electrochemical machining time is 3 min.
