用内转换电子穆斯堡尔谱研究氮离子注入纯铁和GCr15 钢的温度效应

在离子束注入金属材料表面改性的研究中，氮离子束注入钢已被证实是一种很有效的表面改性 方法，它能显著改善钢表面的耐磨性能，但表面性能的改善与注入条件密切相关。本文用内转换电子穆斯堡尔谱分析不同温主廿注入的纯铁和ＧＣｒ１５，并讨论注入温度对改性的影响。

INTERNAL CONVERSION ELECTRONIC MOSSBAUER SPECTRUM OF PURE IRON AND GCr15 STEEL IMPLANTED BY NITROGEN AT DIFFERENT TEMPERATURES

Among methods that use ion implantation to improve metal surface properties, Nitrongen ion implantation in steel is an effective one. It can increase steel surface wear resistance. But this improvement varies with implantation conditions. This paper analyzes the internal conversion electronic Mossbauer Spectrum of pure iron and GCr15 steel samples at different implantation temperatures and also discusses temperature influence on implantation results.
