本文研究了稀土化合物CeCl_3对低温固体多元共渗组织和性能的影响,从自配的多种渗剂中筛选出含CeCl_3的最佳配方,实现了低温固体氧、硫、氮、碳、硼、铈多元共渗,获得了组织和性能远优于其它表面化学处理的渗层。用金相、X射线衍射分析及离子探针等技术对渗层进行了较系统的分析;并对CeCl_3的催渗机理及稀土元素Ce的渗入机理进行了探讨.
In this paper, the effect of rare earth compound CeCl_3 on microstructure and properties of low temperature solid multicomponent co-permeation was studied. The best formula containing CeCl_3 was screened from a variety of osmotic agents, and the solid oxygen, sulfur, nitrogen, carbon, boron, With cerium multicomponent permeation, we obtain nitriding layer with better organization and performance than other surface chemical treatments. The microstructure, microstructure, X - ray diffraction and ion probe techniques were used to systematically analyze the infiltration layer. The mechanism of the infiltration of CeCl 3 and the infiltration mechanism of rare earth element Ce were also discussed.
