摘　　要：本文研究了GCr15钢在100keVN^+离子注入后耐磨性和硬度的变化,用AES、CEMS、XRD等方法对注入层进行了成分和物相分析。实验表明,注入层中的ξ-Fe_2N及ε-Fe^(2+x)(C_7,N)非磁性相能显著提高试样的耐磨性能。在实验条件下,有效改善GCr15钢耐磨性能的N^+注入剂量应≥5×10^(17)N^+/cm^2。The variations of wearability and microhardness have been investigated for GCr15 steel after implantation with 100 keV N+. The composition and phases in the implanted layer were analyzed with AES, CEMS and XRD methods. The experimental results indicated that non-magnetic phases ξ-Fe2N and ε-Fe2+x(C,N) could essentiallly enhance the wearing resistance. To get a satisfactory wearing resistance, a dose of 5×1017N+/cm2 is necessary.
