摘　　要：研究了硼硫，硼氮共渗和最佳工艺及渗硼剂的最佳匹配，渗硼和硼硫，硼氮共渗的渗层组织和性能；Ｎａ２Ｓ２Ｏ３·（ＮＨ２）ＣＯ２在渗硼过程中的催渗和阻渗机制；渗层的脆性，耐磨性和耐蚀性，且证实了不仅在硼齿之间存在有Ｆｅ３（Ｃ，Ｂ）在硼化物的针舌内也存在Ｆｅ３（Ｃ，Ｂ）．This paper deals with the excellent process of borosulphurizing and boronitriding and the proper proportion of borosulphrizng agent. The structures studied. The effects of Na 2S 2O 3and urea on the boronized process were also discussed. The brittleness, wearability and corrobe-resistent were tested as well. This paper still put forward the evibence that there is Fe 3(C,B) not only between, but in acicular-lingulate boron compound.
