Abstract
Cr-Si—N涂层具有较高的硬度,良好的耐磨损抗氧化功能。本文采用磁控溅射沉积方法,以偏压为变量,在三种基片上制备Cr—Si—N涂层。本研究采用X射线衍射仪和扫描型电子显微镜表征偏压对Cr—Si-N涂层的结构的影响;采用纳米压痕仪、残余应力仪、摩擦磨损机等测试偏压对Cr-Si-N涂层的性能的影响。XRD结果显示,随着偏压增加,晶粒变小,并且衍射峰逐渐向小角度偏移。SEM结果显示,随着偏压从0增至-50 V,涂层的柱状晶结构趋于致密化。偏压为0 V,硬度是12.4GPa,偏压增至-50 V,硬度增至35.5 GPa,提高了近两倍。偏压对磨损量影响很小,在偏压为-10 V时,磨损率最小
