摘　　要： 提出了利用稀土化合物CeCl3对Cu-Al-Y合金进行催渗渗铝，研究了工艺参数对渗层厚度和质量的影响；采用工业N2中的余氧作为内氧化介质对Cu-Al-Y合金渗铝后的试样进行内氧化，研究了内氧化层的显微硬度及显微组织。研究结果表明：稀土化合物CeCl3对Cu—Al—Y合金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：内氧化后，采用稀土化合物CeCl3催渗的Cu—Al—Y试样硬度高于未采用稀土化合物CeCl3催渗的Cu-Al-Y试样。 The aluminizing treatment on the surface of Cu-Al-Y alloy with addition of rare earth compound CeCl3 was carded out. The followed intemal oxidation of the aluminized copper was also carried out in the commercial nitrogen gas medium. The influences of the aluminizing and intemal oxidization processing time on the thickness, hardness profile and microstructure were investigated .Results show that the addition of rare earth oxide CeCl3 has great accelerating effect on the aluminizing and intemal oxidation processing. The hardness of the surface Al2O3 dispersion hardened copper composite layer by means of intemal oxidation with addition of rare earth compound is higher than that of the no rare earth compound addition.
