摘要
采用直流磁控溅射镀膜工艺,在不同的氮氩流量比条件下,制备了玻璃基Ti N薄膜。通过X射线衍射仪(XRD)、场发射扫描电子显微镜(SEM、EDS)、纳米显微硬度仪,研究了Ti N薄膜的组织结构、物相组成、表面形貌、元素成份、维氏硬度,分析了氮氩流量比对Ti N薄膜结晶取向、硬度的影响机理。结果表明,在低的氮氩流量比条件下,Ti N薄膜以(111)晶面择优取向;随着氮氩流量比增加,择优取向由(111)晶面向(200)晶面过渡;氮氩流量比为1∶2时薄膜以(200)晶面择优取向;继续增加氮氩流量比(1∶2~2∶1),Ti N薄膜衍射峰强度降低,晶粒尺寸减小;当氮氩流量比增加到2∶1时,薄膜开始呈现非晶态。随着氮氩流量比的增加,薄膜硬度呈现先增加后减小的趋势;当氮氩流量比为1∶1时,Ti N薄膜以(200)晶面择优取向结晶,组织致密均匀,晶粒尺寸最小,具有最大的硬度值(825 HV),相比未镀膜的玻璃基片,硬度值增加了20.44%。
TiN thin films were deposited on commom glass substrates under different N2/Ar flow ratio by DC reactive magnetron supttering. The structure, compositions of phase, morphology, element composition, Vickers hardness of TiN thin films were researched by using X-ray diffraction (XRD), field emission scanning electron microscope (SEM, EDS), nano-hardness tester. The mechanisms of different N2/Ar flow ratio on crystal preferential orientation and hardness of TiN thins film were discussed. The results show that when N2/Ar flow ratio was in low condition, The preferential orientation was ( 111 ). With the increase of N2/Ar flow ratio, the preferential orientation of TiN transforms from ( 111 ) to (200). When N2/Ar flow ratio was 1: 2, The preferential orientation was (200). Continued to increase the N2/Ar flow ratio ( 1 : 2 to 2 : 1 ), the peak intensity of the crystal weakened and size of grain decreased. When the NJAr flow ratio was 2: 1, TiN thin films Show in amorphous. With the increase of N2/Ar flow ratio, the hardness of TiN thin films increased firstly. However, when the N2/Ar flow ratio was increased continuously, the hardness of TiN thin films decreased then. When Ni/Ar flow ratio was 1 : 1, the preferential orientation of TiN thin films was (200), the structure was dense and uniform. And size of grain was the smallest. It had a maximum hardness (825 HV ). Compared to ordinary glass substrates, the hardness increased by 20.44%.
