Figure 7: (a) An example of the metal transfer when 1100 Al is slide on a unimplanted, unrolled ISF steel surface. Spectrum is taken from the debris marked with a dotted box. (b) High magnification image of the debris marked with a dotted box in Figure 5(a). (c) High magnification image of the debris marked with a solid box with EDS spectrum in Figure 5(a). (d) Optical profilometer scan of the metal transfer when 1100 Al is slide on the unimplanted, unrolled ISF steel surface. The dotted black line in the lower right-hand corner is a 50 μm scale bar.
