摘要
用Ｘ射线能谱仪及离子探针对Ｒｅ－Ｎ－Ｃ共渗层中稀土元素晶粒微观尺度上的分布状况进行了分析。结果表明：共渗过程中渗入的稀土元素具有强烈的晶界偏聚倾向。
By means of the X ray spectrometer and ion probe the micro distribution of rare earth elements in a Re N C penetrating layer is analysed. The results show that the Re elements penetrated have a strong tendency of grain boundary segregation in the penetrating process, and there is a high enriching ratio after the penetration.
