- : The durable super-hydrophobic anodic oxide film was prepared on the surface of 6463 aluminum alloy commonly used in the construction industry by anodic oxidation process combined with sealing treatment and low surface energy modification. The morphology , components and surface contact angle of the samples were characterized , and the corrosion resistance and durability were tested through simulation experiments. The results showed that after anodic oxidation , sealing treatment and surface modification , an anodic oxide film with micro-nano hierarchical structure was formed on the surface of aluminum alloy sample , which mainly contained elements Al , O , S , C and Ti , and the surface contact angle reached 153.2 ° , presenting a super-hydrophobic state. The super-hydrophobic anodic oxide film had good binding force and good durability , it can maintain a stable super-hydropho bic state in the natural environment. And it also had good corrosion resistance , which can effectively inhibit the corrosion of aluminum alloy matrix.
