| 摘 要： | 利用稀土化合物CeCl3对纯铜表面渗铝进行催渗。采用工业N2中的余氧作为内氧化介质对纯铜渗铝后的试样进行内氧化，可在纯铜表面制备一层细小弥散的Al2O3粒子。对内氧化层的硬度分布、显微组织及有关性能进行了初步分析。实验结果表明：稀土化合物CeCl3对纯铜渗铝过程具有明显的催渗效果，在同等工艺条件下渗层厚度较高且更加均匀；内氧化后，能在渗铝层形成Al2O3弥散硬化层。

| Abstract: | The aluminizing treatment on the surface of commercial pure copper with addition of rare earth compoundCeCl3 was carried out. The following internal oxidation of the aluminized copper was also carried out in thecommercial nitrogen gas medium. The influences of the aluminizing and internal oxidization processing time on thethickness, hardness profile and microstructure were investigated. Results show that the addition of rare earth oxideCeCl3 has great accelerating effect on the aluminizing and internal oxidation processing. The hardness of the surfaceAl2O3 dispersion hardened copper composite layer by means of internal oxidation with addition of rare earthcompound is higher than that of the no rare earth compound addition. |
