摘　　要：化学热处理就是利用化学反应和物理冶金相结合的方法,改变金属材料表面的化学成分和组织结构,从而使材料表面获得某种性能的工艺过程。化学热处理能有效地提高模具表面的抗氧化性等性能。几乎所有的化学热处理工艺均可用于模具钢的表面处理。根据模具表面的化学热处理目的及基本组成,介绍了模具表面的化学热处理的方法、作用及其工艺过程,研究了模具表面的离子渗氮化学热处理,分析了模具表面的渗碳或碳氮共渗化学热处理,提出了模具表面离子渗硼、渗金属的化学热处理。Chemical heat treatment is the process of combining of chemical reaction with physical metallurgy, soas to change chemical composition and structure on the surface of the metal material, and so a certain performance ofthe material surface can be obtained. Chemical heat treatment can effectively improve the mold surface properties, suchas oxidation resistance. Almost all the chemical heat treatment process can be used for the surface treatment of steels.According to the purpose and procedure of chemical heat treatment on the surface of the mould, the methods, effect andprocess of the chemical heat treatment on the surface of the mold were described; the ion nitriding into mould surfacewas studied; the way of carbonitriding into the surface of the mold was analyzed and the measures for ion boronizing,surface alloying were put forward.
