摘要(Abstract)：

采用非平衡反应磁控溅射的方法在Si(100)基片上沉积Ti(C,N)复合膜和不同调制周期、调制比的TiN/Ti(C,N)纳米多层薄膜。薄膜的微观结构和力学性能采用X射线衍射仪(XRD)、显微硬度计进行表征。结果表明,Ti(C,N)复合膜的微观结构和力学性能与掺入C的含量有关;TiN/Ti(C,N)纳米多层膜的微观结构和力学性能与调制周期和调制比有关,其显微硬度在一定的调制周期和调制比范围内出现了超硬现象。Ti(C,N)、TiN/Ti(C,N)均为δ-NaCl面心立方结构;Ti(C,N)复合膜显微硬度提高是因为固溶强化,TiN/Ti(C,N)纳米多层膜硬度的提高主要是共格外延生长在界面处产生的交变应力场。

关键词(KeyWords)： Ti(C,N)复合膜;TiN/Ti(C,N)纳米多层膜;显微硬度;组织;超硬效应
