The surface was scratched with a sapphire pin and the kind of cracks of film and the relation between destruction of film and scratching force were examined. The increase in thickness of anodic film depresses the destruction of the film and hence improves the wear resistance. Only the lateral crack is observed while the film thickness is less than 40 μm, radial, median, and cone cracks are made by the scratch test of thicker films. In the case of bare aluminum or thin anodic film, the sapphire pin digs into aluminum substrate and the deformation force is larger due to the larger deformation volume.
