Figure 8: (a) SEM image of the debris transferred to the 2e17 ions/cm2, 100 kV N+ implanted ISF steel plate. (b) High Magnification image of the debris within the dotted box. The 7 kV EDS spectra of the debris are included. In addition, Fe, O, and N were detected on the scratched ISF steel surface (red box) at 7 kV. (c) Profilometry scan of the wear debris. The protrusions on the surface exceeded 8 μm in some spots. The white dotted line is a 6 μm scale bar.
