摘要: 本文通过将石墨烯/聚苯乙烯共混溶液涂覆在微弧氧化处理后的AZ91镁合金表面，得到了一种超疏水复合膜层。采用了扫描电子显微镜(SEM)、接触角测试仪、傅里叶红外分析(FTIR)进行表征，研究了超疏水复合膜层的表面形貌、润湿性能和化学组成。采用极化曲线和电化学阻抗方法评价了膜层的耐蚀性能。与未加修饰的镁合金试样比较，超疏水复合膜层的腐蚀电流密度降低了4个数量级，提高了镁合金的耐蚀性能。
Abstract: A super-hydrophobic composite film was prepared by coating the graphene/polystyrene blends on the surface of magnesium alloy after treating by micro arc oxidation method. The scanning electron microscopy (SEM), contact angle tester and Fourier transform infrared spectroscopy (FTIR) were used to characterize the surface morphology, wettability and chemical composition of the super-hydrophobic composite film. In addition, the polarization curves and the electrochemical impedance spectroscopy were also employed to evaluate the anticorrosive property of the coatings. Compared with the unmodified magnesium alloy, the corrosion current density of the super-hydrophobic composite film is reduced by four orders of magnitude, which greatly improved the corrosion resistance of magnesium alloy.
