    Abstract: A method for creating oil-filled porous anodic oxide coatings for stainless steel is disclosed. The coating has anti-corrosion and omniphobic properties to resist both atmospheric conditions, or other conditions with exposure to vapor, and wet conditions, in which the coating is exposed to and/or immersed in liquid. The anodic oxide coating of the present invention can be made by the steps of cleaning and/or electropolishing a steel substrate, applying anodic oxidation to the steel substrate, washing the steel substrate in an organic solvent, and annealing the substrate at high temperature. To fill the porous coating with an oil, a solvent exchange method may be applied.

    Abstract: Embodiments relate to a type of aluminum alloy with grains visible to naked eyes. The aluminum alloy may have an average grain size of at least 100 μηι. The aluminum alloy can be produced by a process such as casting, extrusion, solutionizing, aging, and etching. The solutionizing causes recrystallization of aluminum and causes grains of the aluminum to grow. Compared with the solutionizing, the aging is performed at lower temperature but enhances strength of the aluminum alloy. The etching makes grain boundaries of the aluminum alloy more prominent, rendering the grains of the aluminum alloy visible to a naked human eye.

    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.
