采用简单、环保的水热处理方式结合低表面能物质1H,1H,2H,2H-全氟辛基三乙氧基硅烷(PTES)进行硅烷化处理在AZ31B镁合金表面构建具有微纳米级粗糙结构的超疏水保护性涂层。通过扫描电子显微镜(SEM)和傅里叶红外光谱仪(FT-IR)分别对所制备的超疏水涂层表面形貌和组成进行分析。并用接触角(CA)测试对其表面润湿性能进行分析。结果表明:CA值为164±2°。同时,所制备的超疏水涂层具有优异的耐腐蚀性能、耐久性以及附着力。
A superhydrophobic protective coating with micro/nano-scale roughness was fabricated on the surface of AZ31B magnesium alloy using a simple and environmentally friendly hydrothermal treatment method combined with silanization treatment of low surface energy material 1H,1H,2H,2H-perfluorooctyltriethoxysilane(PTES).The scanning electron microscopy(SEM) and fourier transform infrared spectroscopy(FT-IR) were introduced to analyze the morphology and chemical structure of the prepared surface.The surface wetting properties were analyzed by water contact angle (CA) test showing a CA value up to 164±2°.At the same time,the prepared coating had excellent corrosion resistance,durability and adhesion.
