Cu-Al-Y合金稀土渗铝及内氧化研究

Study on Aluminizing and Internal Oxidation Treatment of Cu-Al-Y Alloy

利用稀土化合物CeCl3对Cu-Al-Y合金表面进行催渗渗铝,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制备Al2O3/Cu复合材料的新方法,并进行了初步的试验研究与理论分析。结果表明:稀土化合物CeCl3在渗铝和内氧化过程中有着明显的促进作用,能在Cu-Al-Y合金表面得到一层均匀的渗铝层。内氧化后,能在渗铝层形成Al2O3弥散硬化层。

The aluminizing treatment on the surface of Cu-Al-Y alloy with addition of rare earth compound CeCl3 was carried out. The followed internal oxidation of the aluminized Cu-Al-Y alloy was also carried out in the commercial nitrogen gas medium. The experimental research and theoretical analysis have been made. Results show that the addition of rare earth oxide CeCl3 has great accelerating effect on the aluminizing and internal oxidation processing. It is possible to generate Al2O3 dispersed hardening layer in the aluminized layer.
