摘要： Manufacturing methods related to anodizing of metal parts are described. In particular, pre-anodizing and post-anodizing methods for forming a consistent and defect-free interface between metal and non-metal sections of a part are described. Methods involve preventing residues from various manufacturing processes from entering a gap or space at the interface between the metal and non-metal section of the part and that can disrupt subsequent anodizing and anodic film dyeing processes. In particular embodiments, methods involve forming a barrier layer or filler layer between the metal and non-metal sections. Portions of the barrier layer or filler layer can be removed prior to anodizing. The resultant part has a well-defined and uniform space between the metal and non-metal sections that is free from visual defects.

摘要： An article having a metal surface is treated to have one or more desired optical effects. The surface is anodized to create an anodic film having pores therein. In some embodiments, an electrodeposition process is performed to deposit one or more metals within the pores of the anodic film. In some embodiments, a pre-dip procedure is performed prior to electrodeposition to create a more uniformly colored anodic film. In some embodiments, one or more dyes are deposited within the pores of the anodic film. In some embodiments, the substrate is exposed to a chemical etching process prior to anodizing to create a micro-textured surface that enhances the richness of the color of the anodic film.

摘要： The embodiments described herein relate to anodizing and anodized films. The methods described can be used to form opaque and white anodized films on a substrate. In some embodiments, the methods involve forming anodized films having branched pore structures. The branched pore structure provides a light scattering medium for incident visible light, imparting an opaque and white appearance to the anodized film. In some embodiments, the methods involve infusing metal complex ions within pores of an anodized. Once within the pores, the metal complex ions undergo a chemical change forming metal oxide particles. The metal oxide particles provide a light scattering medium for incident visible light, imparting an opaque and white appearance to the anodized film. In some embodiments, aspects of the methods for creating irregular or branched pores and methods for infusing metal complex ions within pores are combined.

摘要： The embodiments described herein relate to forming white appearing metal oxide films by forming cracks within the metal oxide films. In some embodiments, the methods involve directing a laser beam at a metal oxide film causing portions of the metal oxide film to melt, cool, contract, and crack. The cracks have irregular surfaces that can diffusely reflect visible light incident a top surface of the metal oxide film, thereby imparting a white appearance to the metal oxide film. In some embodiments, the cracks are formed beneath a top surface of a metal oxide film, thereby leaving a continuous and uninterrupted metal oxide film top surface.

摘要： Anodic films that have a white color, and methods for forming the same, are described. According to some embodiments, the anodic films have multiple metal oxide layers. A first layer can provide scratch and chemical resistance and a second layer can provide a light diffusing pore structure that diffusely reflects incoming light and provides a white appearance to the anodic film. According to some embodiments, the anodic films also include a smoothed barrier layer that specularly reflects incoming light so as to brighten the appearance and enhance the white color of the anodic film. The resulting anodic films have an opaque white appearance not achievable using conventional techniques. The anodic films are well suited for providing cosmetically appealing coatings for consumer products, such as housings for electronic products.
