摘　　要：以锌铝等混合粉为扩渗源,通过热扩渗方法对纯镁进行了Zn-Al-RE三元共渗。通过氧化铈的催渗作用得到了成分不同的渗层,分析渗层中锌含量对渗层耐磨、耐蚀等性能的影响。结果表明:渗层中含有5%锌的渗层具有较好的综合性能。Zn-Al-RE ternary co-cementation was performed to pure Mg by thermal diffusion with Zn and A1 mixed powder as diffusion source. Different components layers were obtained by the catalysis effects of cerium oxides. The influences of Zn content in the layer on the wear-resistance, corrosion resistance were analyzed. The results indicate that the layer with Zn 5% has better general performance.
