摘要(Abstract)：

通过一步水热法在ZK60镁合金表面微弧氧化(MAO)膜层上制备了肉豆蔻酸(MA)修饰的Mg-Al层状双金属氢氧化物(LDH)复合膜层，通过场发射扫描电镜(FE-SEM)、X射线衍射仪(XRD)和傅里叶红外光谱仪(FTIR)分析了膜层的微观形貌、物相成分及结构，通过接触角测定仪及电化学工作站分析了膜层的润湿性及耐腐蚀性能。结果表明：制备的MA/LDH膜层成功封闭了MAO的微孔，水热温度为120℃时制备的MA/LDH/MAO复合膜层表面LDH片层较为完整均匀，其接触角最大，为143.42°。ZK60、MAO膜层及不同水热温度制备的MA/LDH/MAO复合膜层的耐蚀性由大到小依次为MA/LDH/MAO-120>MA/LDH/MAO-110>MA/LDH/MAO-130>MAO>ZK60,这归因于MA/LDH/MAO-120膜层具有均匀完整的LDH结构及MA插层/表面修饰LDH作用，可有效提高ZK60镁合金的耐蚀性能。
