电弧离子镀TiN涂层陶瓷刀片的力学性能和界面结构

Mechanical Property and Interface Structure of TiN-coated Ceramics Insert by Arc Ion Plating Process

采用电弧离子镀技术在氧化铝基陶瓷刀片表面沉积了ＴｉＮ涂层．结果表明：ＴｉＮ涂层陶瓷刀片的抗弯强度和Ｗｅｉｂｕｌｌ模数有较大的提高．扫描电子显微镜、Ｘ射线衍射、二次离子质谱分析表明：涂层表面平整光滑，为立方ＮａＣｌ结构，并且呈现出明显的（２２０）择优取向．涂层与基体结合紧密，两者存在着明显的元素扩散．

TiN coating was deposited on alumina based ceramics insert by arc ion plating process and enhances the flexural strength and Weibull modulus effectively. The results of SEM, XRD and Secondary Ion Mass Spectrometry (SIMS) indicate that the flat and smooth coating is of cubic structure, having (220) preferred orientation. The coating adheres to the substrate compactly and both of them have interdiffusion near the interface.
