Abstract: The preparation and properties of combined aluminium oxide coatings have been investigated. The coating has been prepared in two steps. First, aluminium substrate was anodically oxidized. In the next step the anodized film has been coated by the sol-gel method. The conditions of forming coatings without shrinkage were obtained empirically. It was found out that the film prepared by the sol-gel method has the same crystal structure as the oxide film prepared by the anodic oxidation. The thickness, phase analysis, and surface microstructure of obtained coatings were determined.
