| 摘 要： | 采用纳米CeO2和Zn粉成功制备出CeO2/Zn纳米复合材料作为镀层材料,并利用X射线衍射、场发射扫描电镜等测试分析手段,对复合材料组织结构进行研究,比较了不同纳米CeO2含量复合材料的耐蚀性和硬度。结果表明:纳米CeO2颗粒的加入能显著提高金属的耐蚀性、硬度和金属结构的致密均匀性,并在纳米CeO2含量为1%时显示了最佳的耐蚀性、硬度和微观组织结构。

| Abstract: | Compared with ordinary coatings, nano-composite coating usually has a higher hardness and better wear and corrosion resistance. As coating materials, nano-CeO2/Zn composites were prepared by nano-CeO2 and Zn powder. The microstructure was investigated by XRD and FESEM. The corrosion resistance and hardness of nano-CeO2/Zn composites with different amount of nano-CeO2 were comparatively studied. The results show that the metal corrosion resistance, hardness and density of the comPosites may be improved significantly by addition of nano-CeO2, and the optimal amount of nano-CeO2 is 1%. |
