摘要: 

利用扫描电子显微分析(SEM)、X射线衍射分析(XRD)、中性盐雾实验以及电化学交流阻抗等技术,研究了Al粉的形态与尺寸对热烧结锌铝涂层表面形貌、耐蚀性及其在海水中电化学性能的影响。结果表明,Al粉的存在改善了涂层外观色泽、提高了涂层耐蚀性和控制了涂层中的Zn粉在腐蚀介质中溶解消耗的速率,从而延长了涂层寿命,其中尺寸较小、分散性好的Al粉效果更好。

Abstract

The effects of aluminum powders with different shapes and sizes on the surface morphology, corrosion
resistance and electrochemical behavior of the coating were studied by means of scanning electron microscope
(SEM), X-ray diffraction(XRD), neutral salt spray test and electrochemical impedance spectroscopy. The
results show that aluminum powders can improve the appearance of the coatings, and can also increase the
corrosion resistance of the coatings by extending the electrochemical protection term of zinc powders, with a
better effectiveness for the small-size and well-dispersed Al powders.
