| 中文摘要: |
| 采用电沉积方法,通过向镀液中加入不同粒径的CeO2 颗粒,制得Zn-Ni/微米CeO2 复合镀层和Zn-Ni/纳米CeO2 复合镀层,研究了CeO2 粒子的大小和加入量对镀层微观形貌、相组成、CeO2 在镀层中的复合量以及镀层耐蚀性的影响。结果表明:大量加入CeO2,可使镀层呈现块状的“饼干暠结构,并能提高镀层的耐蚀性,此外还可以抑制Ni的沉积,加入10g/L纳米CeO2 时,镀层的合金相主要为Ni2Zn11相,其它Zn-Ni合金相则较少;相比之下,在提高镀层CeO2 复合量方面,微米级CeO2 效果较好,在提高镀层耐蚀性方面,纳米级CeO2 的效果较好。 |
| 英文摘要: |
| The Ni-Zn/micro-CeO2 composite material and Ni-Zn/nano-CeO2 composite material were produced by electrodeposition method through adding micro- and nano-CeO2 particles in the Zn-Ni plating bath. The effects of the diameter and the concentration of the CeO2 particles on the microtopography, phase component, CeO2 content and the corrosion resistance of the Ni-Zn coating were studied. The result shows that when the concentration of the CeO2 particles is high, the Ni deposition is inhibited; The composite coatings are characterized with laminate morphology with good corrosion resistance. When the concentration of the nano-CeO2 particles is 10g/L, the major alloy phase is Ni2Zn11. Compared with the nano-composite coating, the CeO2 content is larger in the micro-CeO2 composite coating. But the corrosion resistance of the nano-CeO2 composite coating is larger than that of the micro-CeO2 ones. |
