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。
In this paper, the changes of wear resistance and hardness of GCr15 steel after 100 keVN + ion implantation were studied. The composition and phase of the implanted layer were analyzed by AES, CEMS and XRD. Experiments show that the ξ-Fe_2N and ε-Fe ~ (2 + x) (C_7, N) non-magnetic phase in the implanted layer can significantly improve the wear resistance of the sample. Under the experimental conditions, the dosage of N ~ + which can effectively improve the wear resistance of GCr15 steel should be ≥5 × 10 ~ (17) N ~ + / cm ~ 2.
