Fractal analysis of engineering ceramics ground surface

► In general, the texture in engineering ceramics surface is fine and dense, when the fractal dimension is high. ► The size order of fractal dimension is steel, zirconia, silicon nitride and alumina. It is the same as the order of fracture toughness of four materials. ► With the higher value of the fractal dimensions, they can indicate the better wear resistance for the same material.
