The distribution of microhardness is not uniform across the anodic film for the most specimens and the general trend is that the value of the hardness is higher both in the outer film adjacent to the surface and in the inner film near the interface between film and substrate for the specimens with type Ⅱ and type Ⅲ anodizing technology. The measured modulus for anodic film with type Ⅲ anodized is 80.77Gpa. The thermal expansion coefficients of anodic films are measured by two different methods based on X-ray diffraction technique. One way is to detect the lattice spacing change of crystalline phase in powder specimen of anodic film as the increment of temperature by powders of anodic film; and the other way is to determine the thermal stress by entire specimen, that is, the anodic film and the substrate attached together.
