Patent number: 11131036Abstract: 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.Type: GrantFiled: October 31, 2016Date of Patent: September 28, 2021Assignee: APPLE INC.Inventors: Masashige Tatebe, Jody R. Akana, Takahiro Oshima, Peter N. Russell-Clarke, Ayumi Hongou, Kenji Hara

Patent number: 10781529Abstract: Anodizing techniques for providing highly opaque colorized anodic films are described. According to some embodiments, the methods involve depositing a pigment having a particle diameter of about 20 nanometers or greater into an anodic film. Additionally or alternatively, a barrier layer smoothing operation is used to flatten an interface between the anodic film and underlying metal substrate so as to maximize light reflection off the interface, thereby maximizing light reflected off the pigment that is deposited within pores of the anodic film. The resulting anodic films have an opaque or saturated colored appearance. In some embodiments, the methods involve increasing a thickness of a non-porous barrier layer of the anodic film so as to create thin film interference effects that can add a particular hue to the anodic film. The methods can be used form cosmetically appealing coatings for consumer products, such as housings for electronic products.Type: GrantFiled: October 24, 2016Date of Patent: September 22, 2020Assignee: APPLE INC.Inventors: Masashige Tatebe, Takahiro Oshima, Jody R.

Patent number: 10760175Abstract: 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.Type: GrantFiled: October 24, 2016Date of Patent: September 1, 2020Assignee: APPLE INC.Inventors: Masashige Tatebe, Takahiro Oshima, Jody R.

Patent number: 10434602Abstract: 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.Type: GrantFiled: November 17, 2017Date of Patent: October 8, 2019Assignee: Apple Inc.Inventors: Daniel T.

Publication number: 20170253986Abstract: A surface treatment for metal surfaces can be used to create one or more desired effects, such as functional, tactile, or cosmetic effects. In one embodiment, the treatment involves selectively masking a portion of the surface using a photolithographic process. The mask can protect the masked portion of the surface during subsequent treatment processes such as texturizing and anodization. The mask can result in the creation of a surface having contrasting effects. A pattern can be formed by the contrasting effects in the shape of a distinct graphic, such as a logo or text.Type: ApplicationFiled: May 18, 2017Publication date: September 7, 2017Inventors: Jody R.

Patent number: 9644281Abstract: 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.Type: GrantFiled: October 2, 2013Date of Patent: May 9, 2017Assignee: Apple Inc.Inventors: Masashige Tatebe, Takahiro Oshima

Publication number: 20170121837Abstract: Anodic films that provide improved corrosion resistance to high performance aluminum alloys, and methods for forming the same, are described. According to some embodiments, the anodic films have a dense porous layer and a thickened barrier layer. The porous layer can act as a cosmetic portion of the anodic film and have pores that have a colorant infused therein. The thickened barrier layer can distribute defects within the anodic film associated with alloying elements of the high performance aluminum alloy in a larger non-porous film compared to conventional anodic films, thereby lessening the chance of corrosion inducing agents of reaching the high performance aluminum alloy. The anodic films have superior scratch and chemical resistance, as well as enhanced cosmetic aspects, well suited for consumer products, such as housings for electronic products.Type: ApplicationFiled: October 24, 2016Publication date: May 4, 2017Inventors: Masashige TATEBE, Takahiro OSHIMA, Jody R.
