  • Patent number: 10781529
    Abstract: 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.

  • Patent number: 10760175
    Abstract: 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.

  • Patent number: 10744547
    Abstract: A method of producing a press-formed product includes a steel plate heating step, a hot forging step and a hot stamping step. In the steel plate heating step, a steel plate is heated to 950° C. or more. In the hot forging step, the heated steel plate is forged to form a varying-thickness steel plate. In the hot stamping step, the heated varying-thickness steel plate is subjected to press-working by a press tooling to form a press-formed product, and the press-formed product that is formed is cooled inside the press tooling. Thus, a press-formed product that has high strength and for which a reduction in weight is possible can be produced.
