摘要:

利用一步水热法在AZ91D镁合金表面原位制备ZnAl-LDHs薄膜和ZnAlCe-LDHs薄膜，借助X射线衍射仪、扫描电镜、能谱仪和电化学阻抗谱等表征手段，研究Ce对镁合金表面ZnAlCe-LDHs薄膜形貌结构、化学组成及耐腐蚀性能的影响。结果表明，Ce离子加入不改变镁合金表面LDHs鸟巢网状形貌，但增加了薄膜的厚度以及纳米片的尺寸。EIS结果表明，ZnAlCe-LDHs薄膜与ZnAl-LDHs薄膜相比，自腐蚀电位正移0.05 V，腐蚀电流密度降低1~2个数量级，阻抗图中容抗弧半径明显增大，说明加入Ce离子可以增强镁合金的耐腐蚀性能。

Abstract：

Thin films of layered double hydroxides (LDHs) such as ZnAl-LDHs and ZnAlCe-LDHs were grown in situ on the surface of AZ91D Mg-alloy via one-step hydrothermal method. The influence of Ce on the morphology, chemical composition and corrosion resistance of ZnAlCe-LDHs films on Mg-alloy was studied by means of X-ray diffractometer (XRD), scanning electron microscope (SEM), EDS and EIS. The results showed that Ce ion had little effect on the network-like morphology of LDHs nests, but increased the thickness of the films and the size of the nanosheets. In comparison with ZnAl-LDHs films, the free-corrosion potential of ZnAlCe-LDHs films shifted positively up to 0.05 V and the corrosion current density was decreased by 1~2 orders. In the impedance diagram, the arc radius was increased obviously, indicating that the addition of Ce ion can enhance the corrosion resistance of ZnAl-LDHs films on AZ91D Mg-alloy.

Key words： Ce Mg-alloy ZnAlCe-LDHs corrosion resistance mechanism
