| Abstract: | An aluminizing technique with RE CeCl_3 on pure copper is presented. Al_2O_3 particles dispersed on Cu surface have been fabricated by aluminizing and internal oxidation technique. The influence of the technologic parameters on aluminizing layer and the microstructure and properties of the aluminized copper after internal oxidation is studied. The results show that it has deeper aluminizing layer using RE CeCl_3 than that of without using RE CeCl_3 at the same technologic parameters. It is possible to generate Al_2O_3 dispersed hardening layer in the aluminized layer. |
