【摘要】 研究了工业纯铁离子注N后的连续CO₂激光热处理效应。用AES、TEM、SEM和X射线衍射等测试技术,研究了注N试样在激光热处理前后N原子的深度分布和组织结构,提出了注N纯铁在激光作用下N原子的热扩散模型。更多还原

【Abstract】 The effect of CW CO2 laser beam irradiation on nitrogen ion-implanted ARMCO iron specimens has been studied in this paper.Auger Electron Spectroscopy, Transmission Electron Microscopy,Scanning Electron Microscopy and X-ray Diffrac-tion have been used to study the depth distributions of the implanted nitrogen and the surface structure of ARMCO iron specimens implanted with nitrogen before and after laser treatment. The thermal diffusion model of nitrogen atoms in nitrogen ion-implanted ARMCO iron irradiated by CO2 laser hast been pointed out.更多还原
