离子渗氮提高硬质膜层与普通结构钢基体结合力的研究

To enhance the binding force between hard coating and a common structure steel substrate by ion nitriding

选用４０Ｃｒ作基体材料，ＴｉＮ作膜层材料，在离子镀膜前进行离子渗氮预处理，性能测试与结构分析证实渗氮层的存在可以缓解膜基性质的差异，提高膜基结合力．

おhere lies some questions that coating can't bind tightly with substrate to apply ionplating hard film technique on common structure steel. Selecting 40Cr as substrate material and TiN as film material, we made 40Cr ionnitrided before ionplating, and results show that difference at component and hardness between coating and substrate can be decreased and binding force can be increased through ionintriding before ionplating.
