摘　　要：通过扫描电镜、能谱分析、X射线衍射分析等方法,对4Cr5MoSiV1钢硼铝稀土共渗层组织与性能进行了研究。结果表明,共渗层主要由FeB相构成,没有发现(Fe,Al)B或(Fe,Al)2B物相;共渗层组织连续致密,具有很高的显微硬度和热硬性。The microstructure and properties on the RE-Al-boronized layer of 4Cr5MoSiV1 steel was researched by SEM,energy spectrum and X-ray diffration analgsis.The results show that the RE-Al-bronized layer may be consisted of phases FeB without (Fe,Al)B or (Fe,Al)_2B,and the microstructure of the layer is continuous and compact, the layer possess high microhardness and red hardness.
