| Abstract | 利用Ni与CeO2纳米颗粒共电沉积制备了纳米结构的Ni—CeO2复合镀层，Ni平均晶粒尺寸为（56±38）nm；对比研究了该复合镀层与粗晶Ni（平均晶粒尺寸约为30μm）在700℃扩散渗铬5h后的渗层结构．结果表明，纳米复合镀层上的渗层厚度和渗入Cr浓度都远高于粗晶Ni；800℃下20h的恒温氧化实验结果表明，纳米复合镀层上渗铬层的抗氧化性能与粗晶Ni相比显著提高． |
| Other Abstract | A nanostructured Ni-CeO2 composite film was fabricated on A3 carbon steel by co-electroplating Ni with nanoparticles of CeO2. The mean grain size of the deposited Ni was about 56 ± 38 nm. Then the Ni-CeO2 composite and a coarse-grained Ni （mean grain size 30 m） were chromized by pack cementation at 700℃ for 5 h. The results showed that the chromium content and thickness of the chromized layer were greatly increased on the composite compared to those on the coarse-grained Ni. Oxidation at 800℃ for 20 h indicated that the chromized Ni-CeO2 composite film showed a better oxidation resistance compared to the chromized coarse-grained Ni. |
