摘　　要：研究了离子镀（Ｔｉ，Ｃｒ）Ｎ涂层的组织结构和耐蚀性，经ＸＲＤ分析表明，（Ｔｉ，Ｃｒ）Ｎ涂层中的Ｃｒ原子部分置换ＴｉＮ晶格中的Ｔｉ原子，且部分与Ｎ反应生成ＣｒＮ，Ｃｒ２Ｎ，或以单质态存在．经耐蚀性分析得知，由于Ｃｒ的加入，提高了（Ｔｉ，Ｃｒ）Ｎ涂层的致密度，同时加剧了阴极极化程度，延长了腐蚀原电池的开动过程，从而增强了涂层的耐蚀性．The structure and corrosion-resisting property of the coating of ion plating(Ti,Cr)N are studied in this paper Analyzed with XRD,it is showed that some Cr atoms in the(Ti,Cr)N coating partly replaced Ti atom in the TiN lattice,some react with N to form CrN and Cr 2N,others keep their original existance The experiment on corrosion-resisting property indicates that,due to the introduction of Cr into the(Ti,Cr)N coating,the compactness of the coating is improved,the negative pole is much more polarized,and the starting procedure of the corrosion battery is prolonged,manifests the improvement in corrosion-resisting property of the coating
