| 摘 要： | 利用纳米压痕实验测定了氮化钛薄膜/高速钢基体中薄膜的弹性模量和硬度,并得到了纳米压痕过程的载荷—位移曲线;根据实验所得材料参数建立了纳米压痕实验的DEFORM计算模型,利用该有限元模型分析了不同薄膜厚度的膜/基结合处的切应力分布,研究了膜/基分离的可能性大小及分离位置与薄膜厚度的关系。

| Abstract: | It study measured the modulus and hardness of the film of Titanium Nitride thin film/High-Speed steel substrate by nanoindentation experiment,and get the load-displacement curve;It simulated the process of the nanoindentation experiment by the DEFORM,and the shear stress of film/substrate is calculated by using FEM,the detachment possibility of film/substrate and the relation between detachment position and film thickness are also investigated. |
