对N_2~+离子注入的GCr15轴承钢样品进行了俄歇分析。样品分为两类:氮注入的GCr15钢和GCr15钢镀Cr后用氮轰击。两者的注入条件相同,能量为100KeV,剂量为3×10~(17)N_2~+/厘米~2和6×10~(17)N_2~+/厘米~2。俄歇分析清楚地给出了有关注入情况的信息,如离子注入对氧在钢表面吸附的影响,氮在钢表层的分布以及在不同剂量下Cr向基体内推移的情况等。观察到最大相对浓度的饱和值,在我们的实验条件下约为23at％。 Auger analysis of GCr15 bearing steel samples with N_2 ~ + ion implantation was carried out. The samples were divided into two categories: Nitrogen-infused GCr15 steel and GCr15 steel were plated with Cr and bombarded with nitrogen. The injection conditions were the same with energy of 100 KeV and dose of 3 × 10 ~ (17) N_2 ~ + / cm ~ 2 and 6 × 10 ~ (17) N_2 ~ + / cm ~ 2. Auger analysis clearly gives information on the conditions of implantation, such as the effect of ion implantation on the adsorption of oxygen on the steel surface, the distribution of nitrogen on the steel surface, and the shift of Cr into the matrix at different doses. The saturation at the maximum relative concentration was observed, at about 23 at% under our experimental conditions.
