【摘要】 采用等离子体源离子注入方法,将氮离子注入纯铁粉中,对样品进行穆斯堡尔谱研究.对注氮前后样品的无反冲因子f、同质异能移位δ、电四极裂距ΔEQ进行了比较分析.解释了氮离子注入钢材表面其硬度和耐磨性提高的原因.更多还原

【Abstract】 Mssbauer measurements have been carried out for pure iron powder samples, the whose surface was implanted with nitrogen ions by plasma source ion implantation techniques. The measured Mssbauer parameters, Mssbauer factor \%f\%, Isomer shifts δ and quadrupolar splitting Δ E\- Q,for samples of unimplanted with nitrogen are compared with those of implanted ones.From this study we understand how ion implantation improves surface properties of iron.更多还原
