摘要
用原位化学气相沉积方法在Ｃｒ１７Ｎｉ２钢表面共渗铬硅，通过工艺优化，获得了含铬２７ｗｔ％、含硅２ｗｔ％左右的渗层，渗层厚度约为１２０μｍ，渗层为单相的α固溶体。共渗后的热处理工艺对渗后材料的力学性能有较大的影响。
In situ codeposition of Cr and Si into steel Cr17Ni2 has been achieved using pack cementation. Through optimizing the processing parameters,a coating containing about 27wt% Cr and 2wt% Si has been obtained, and the layer thickness is about 120μm. Heat treatment process after codeposition has great effect on mechanical properties.
