摘要：

[目的]为了提高5083铝合金的耐蚀性，在其表面制备了超疏水抗菌复合涂层。[方法]首先对铝合金进行微弧氧化处理，然后将加了硅烷改性TiO₂和ZnO纳米粒子的环氧涂料喷涂在其表面，制得厚度约400μm的复合涂层。采用扫描电镜(SEM)及X射线衍射仪(XRD)考察了微弧氧化膜及复合涂层的表面形貌和物相组成，通过动电位极化曲线测试、接触角测量和平板涂布计数法对涂层的耐蚀性、疏水性和抗菌性进行考察。[结果]当纳米TiO₂和ZnO的质量比为1∶1时，复合涂层的耐蚀性最好，水接触角达到164.12°，滑动角低至2.10°，对大肠杆菌、金黄色葡萄球菌和铜绿假单胞菌的抗菌率分别为99.32%、99.85%和91.17%。[结论]通过微弧氧化与纳米复合涂层技术相结合，可明显提高5083铝合金的耐蚀性、疏水性和抗菌性。

Abstract：

[Objective] To improve the corrosion resistance of 5083 aluminum alloy, a superhydrophobic and antibacterial composite coating was fabricated on its surface. [Method] The aluminum alloy was treated by micro-arc oxidation initially, and then sprayed with an epoxy paint containing silane-modified TiO₂ and ZnO nanoparticles, forming a ca.400 μm-thick composite coating. The surface morphology and phase constitution of the micro-arc oxidation film and composite coating were examined using scanning electron microscope(SEM) and X-ray diffractometer(XRD), while the corrosion resistance, hydrophobicity, and antibacterial performance of the coating were tested by potentiodynamic polarization measurement, contact angle measurement, and plate count method. [Result] The composite coating prepared at a TiO_2-to-ZnO mass ratio of 1:1 showed the optimal corrosion resistance with a water contact angle up to 164.12° and a sliding angle as low as 2.10°. The antibacterial rates of the composite coating against Escherichia coli, Staphylococcus aureus, and Pseudomonas aeruginosa were 99.32%, 99.85%, and 91.17%, respectively. [Conclusion] The combination of micro-arc oxidation and nanocomposite coating technologies greatly enhances the corrosion resistance, hydrophobicity, and antibacterial performance of 5083 aluminum alloy.
