摘要

利用磁控溅射方法

通过改变氮气流量制备出ZrN纳米涂层

研究了氮气流量对ZrN纳米涂层结构及硬度的影响

并采用表面轮廓仪、X射线衍射仪、扫描电镜及纳米压痕表征了ZrN纳米涂层的厚度、相结构、形貌及硬度.实验结果表明

随着氮气流量增加

涂层厚度减小

涂层择优取向由(111)变为(200)

对应的截面形貌由柱状结构变为非柱状结构; 传统的位错滑移机制不适用于ZrN纳米涂层的塑性变形

其硬度随择优取向和晶粒尺寸的增大而增加.

Abstract

The influences of nitrogen flow percentage on microstructure and hardness of ZrN nano-coatings fabricated by DC magnetron sputtering were investigated. The thickness

phase structure

morphology of cross-section and hardness of ZrN nano-coatings were characterized with profilometer

X-ray diffraction

scanning electron microscope and nanoindentation. The results show that the nitrogen flow percentage significantly affects the thickness and phase structure of ZrN nano-coatings. With increasing nitrogen flow percentage

the coating thickness decreases and the phase structure evolves from the orientation(111)to(200)

the cross-section morphology changes from columnar structure to non-columnar structure as well. For the ZrN nano-coating

the dislocation sliding is not the cause for plastic deformation

and the hardness increases with the increasing grain size and preferred orientation.
