摘　　要：本文初步研究了固体粉末法硼铬共渗技术,并得出:用固体粉末法可实现硼铬共渗;共渗层中除有硼化铁Fe_2B或(Fe,Cr)_2B)以及固溶体外,碳化铬(Cr,Fe)_7C_3也可以成相;并得到了两层化合物组成的结构,其中(Cr,Fe)_7C_3为连续层.In this paper pack boron-chromizing have been studied. It is shown that pack boron - chromizing can proceed. In B -Cr layer (Cr, Fe)7C3 is a phase besides (Fe, Cr)2B and solid solution. A two - phase structure layer, which contains (Fe, Cr)2B phase and (Cr, Fe)7C3 continuous phase, can be obtained.
