The worn surfaces of the specimens were examined using FE-SEM
to elucidate the modes of the wear process. Fig. 11 shows the images
of wear tracks at lower magnification and higher magnification
(inset) for samples A, B, C, D, and E. From this figure, the worn tracks
of the carburized samples indicate that the shallower groove wear
pattern is dominant on PC sample. Again, this proven excellent wear
resistance was produced on the PC sample.
