| 摘 要： | 采用磁控溅射在TNMG120408型号的硬质合金刀片上沉积了TiN/Ti(C,N)单层与多层涂层,通过XRD、SEM、纳米压痕、划痕仪与冲击测试等方法,比较分析了TiN/Ti(C,N)涂层的显微组织与力学性能。结果表明,TiN单层涂层的晶粒形貌为典型的喇叭口结构,Ti(C,N)单层涂层为平直的柱状晶结构;而TiN/Ti(C,N)多层涂层为柱状晶结构,形成了TiN、Ti(C,N)交替排列的结构。TiN与Ti(C,N)单层涂层均呈(220)生长织构,而TiN/Ti(C,N)多层涂层呈(111)生长织构。Ti(C,N)单层涂层表现出较好的硬度,而TiN/Ti(C,N)多层涂层则表现出与基体更好的结合力。

| Abstract: | TiN/Ti(C,N) coatings grown on cemented TNMG120408 carbide substrate were synthesized using magnetron sputtering technique.The microstructure and mechanical properties of the coatings were investigated using X-ray diffraction(XRD),scanning electron microscopy(SEM),nanoindentation,scratch and impact tests.The results show that the bell mouth columnar structure and the straight columnar structure are observed in TiN and Ti(C,N)coatings,respectively.The both TiN and Ti and Ti(C,N) coatings show(220) preferred o... |
