| 摘 要： | 采用高能球磨法制备了纳米CeO2/Zn复合粉末,用粉末冶金真空热压烧结制备了纳米CeO2/Zn复合材料块体,利用X射线衍射(XRD)、场发射扫描电镜(FESEM)等测试分析手段,对复合粉末、块体组织结构进行了研究。并研究比较了不同纳米CeO2含量的锌复合材料的耐蚀性和硬度,找出了耐蚀性和硬度最好时CeO2的最佳含量范围。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。并于纳米CeO2含量在1%时显示了最佳的耐蚀性、硬度和微观组织结构。

| Abstract: | The nanocomposite powders and nanocomposite materials of CeO2/Zn was prepared by high energy ball milling and vacuum hot pressed calcinations of powder metalurgy, respectively. The microstructure was investigated by XRD and FESEM. The comparison of their corrosion resistance and hardness in different amount of nano-CeO2 was performed, and the optimal amount of nano-CeO2 was found. The results show that metal corrosion resistance, hardness and the density of metal structure can be improved significantly in presence of metal within nano-CeO2, and the optimal corrosion resistance, hardness and microstructure was found in 1% amount of nano-CeO2. |
