摘　　要：简述了TD法盐浴渗金属的机制和所用设备的结构。较详细介绍了T10、Cr12、GCr15、W6Mo5Cr4V2和4Cr5MoSiVl等常用模具钢TD法渗钒、渗铬和渗铌的盐浴成分,所得到的覆层的组织、性能及其影响因素;TD法渗金属工艺参数对覆层厚度的影响;Crl2钢用含稀土的盐浴TD法渗铬覆层的显微组织;T10钢TD法盐浴渗铌覆层的相结构。The mechanism and equipment were briefly described in terms of TD salt bath metal cementation. The fbllowing points were introduced in more detail： （a） compositions of salt baths for vanadinizing, ehromizing and niobiumizing of commonly used die steels such as TI0, Crl2, GCrl5, W6Mo5Cr4V2 and 4Cr5 MoSiV1 with the use of TD technique; （b） the microstructure and property of the resulting coatings and the factors influencing them; （e） the effect of process parameters of TD salt bath metal cementation on the coating thickness; （d） the microstructure of coating of Cr12 steel TD chromized in RE-containing salt bath; （e） the phase structure of coating of T10 steel TD salt bath niobiumized.
