摘    要:用脉冲直流等离子体辅助化学气相沉积(PCVD)设备在狭缝的侧壁上沉积Ti-Si-N薄膜.经微观物相分析发现,在狭缝的侧壁上随着测试深度的增加,薄膜中Ti元素逐渐减少,Si含量增加,薄膜的相组成始终为nc-TiN/Si3N4.利用球痕法测定了各深度处薄膜的厚度,显微硬度仪测试了侧壁上深度不同位置处薄膜显微硬度.实验结果表明,随测试深度增加,薄膜厚度和显微硬度下降.

关 键 词:PCVD  Ti-Si-N  复杂型腔  模具

Abstract:Ti-Si-N films were coated on inner walls of a 3 mm wide slit of high speed steel (HSS) by pulsed d.c. plasma enhanced chemical vapor deposition (PCVD) to simulate film growth on surfaces of moulds and dies with complicated geometry.The coating were studied with X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS).We observed that as the measured spot goes deeper down the slit,the film thickness,its micro-hardness as well as the Ti content decrease,but the Si content increases.The results show that crystalline TiN nano-particles coexist with amorphous Si 3N 4 throughout the films.
Keywords:PCVD  Ti-Si-N  Complex-shaped surface  Mould
