    Abstract: 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.

    Abstract: Anodizing techniques for providing enhanced anodic films are described. According to some embodiment, a barrier layer smoothing operation is used to flatten an interface between the anodic film and underlying metal substrate. According to some embodiments, the methods involve depositing a pigment having a particle diameter of about 20 nanometers or greater into an anodic film. 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 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 methods can be used form cosmetically appealing coatings for consumer products, such as housings for electronic products.

    Abstract: 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.

    Abstract: 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.

    Abstract translation: 描述了用于提供增强的阳极膜的阳极氧化技术。 根据一些实施例，使用阻挡层平滑操作来平坦化阳极膜和下面的金属基底之间的界面。 根据一些实施方案，所述方法涉及将具有约20纳米或更大粒径的颜料沉积到阳极膜中。 根据一些实施例，阳极膜具有多个金属氧化物层。 第一层可以提供耐刮擦性和耐化学性，第二层可以提供漫反射入射光并为阳极膜提供白色外观的光漫射孔结构。 根据一些实施例，阳极膜具有致密多孔层和增厚的阻挡层。 多孔层可以充当阳极膜的装饰部分并且具有其中注入着色剂的孔。 与传统的阳极膜相比，增厚的阻挡层可以将与高性能铝合金的合金元素相关的阳极膜内的缺陷分布在较大的无孔膜中，从而减少腐蚀诱导剂到达高性能铝合金的机会。 这些方法可用于消费品的美观吸引涂料，例如电子产品外壳。
