SEM micrographs of 3000-cyclic indentation morphologies. (a) Hertzian ring cracks with large-scale inner and outer edge chippings and (b) large-scale fractures in the roughest CAD/CAMed-sintered-glazed surface; (c) Hertzian ring cracks with large-scale outer edge chippings and (d) large-scale fractures in the rough CAD/CAMed-sintered LDGC surface; (e) Hertzian ring cracks with inner and outer edge chippings and (f) fractures in the CAD/CAMed-sintered-polished surface; (g) Hertzian ring cracks with large-scale inner and outer edge chippings and (h) large-scale fracture surface with transverse crack propagations in the smooth CAD/CAMed-polished-sintered-glazed surface; and (i) Hertzian ring cracks with outer edge chipping and (j) fractures in the smoothest CAD/CAMed-polished-sintered surface.
