The results show that the structures of theouter layer of ion-nitriding are s (Fe_2-3N)-phase and γ′(Fe_4N)-phase, which are arranged in alternating, ribbon-like strips. There are many various crystal defects, such as vacancies, dislocations,stacking faults,and twins in the internal layer compound——the γ′- phase. The interfaces between ε-phase and γ′ -phase are smooth and straight. Ledges of monoatom layers and multiatom layers were found. The existance of a number of crystal defects is the main reason why ion bombing accelerates the nitriding process.
