Propagation of introduced crack in Al2O3/Ti composite (a) and healed cracks after anodization at room-temperature (b, c and d), where cracks at dispersed titanium (white particles) as well as part of cracks at Al2O3 ceramics were filled by the formed titanium oxides. Fracture strength of cracked-composites was greatly decreased, but was almost fully recovered to its original level (right).
