Abstract: Processes for enhancing the corrosion resistance of anodized substrates are disclosed. In some embodiments, the process involves a second anodizing operation that targets an area of the substrate that is left inadequately protected by a first anodizing operation, and also targets defects that may have been arisen from intermediate processing operations such as laser-marking operations. The second anodizing operation can be conducted in a non-pore-forming electrolyte, and grows a thick protective barrier film over inadequately protected areas of the substrate, such as laser-marking treated areas.

Abstract: Treatments for anodic coatings that provide improved resistance to staining and cracking during various manufacturing processes are described. According to some embodiments, the methods include placing the anodic coatings in partially sealed states by sealing only the outermost portions of the anodic coatings, which protect the outer surfaces of the anodic coatings from contamination and staining. Inner portions of the anodic coatings are left unsealed, thereby making the anodic coatings more compliant and resistant to cracking when exposed to manufacturing processes, even those that involve exposure to high temperatures or high mechanical stress. Subsequent to the processing, another sealing process can be implemented to fully seal the anodic coatings so that they provide good corrosion and wear resistance.

Abstract: Anodic oxide coatings that provide corrosion resistance to parts having protruding features, such as edges, corners and convex-shaped features, are described. According to some embodiments, the anodic oxide coatings include an inner porous layer and an outer porous layer. The inner layer is adjacent to an underlying metal substrate and is formed under compressive stress anodizing conditions that allow the inner porous layer to be formed generally crack-free. In this way, the inner porous layer acts as a barrier that prevents water or other corrosion-inducing agents from reaching the underlying metal substrate. The outer porous layer can be thicker and harder than the inner porous layer, thereby increasing the overall hardness of the anodic oxide coating.

Abstract: This application relates to an anodized part. The anodized part includes a metal substrate and an anodized layer overlaying and formed from the metal substrate. The anodized layer includes (i) an external surface that includes randomly distributed light-absorbing features that are capable of absorbing visible light incident upon the external surface, and (ii) pores defined by pore walls, where color particles are infused within the pores. The anodized layer is characterized as having a color having an L* value using a CIE L*a*b* color space that is less than 10.
