Abstract: The embodiments described herein relate to anodic oxides and methods for forming anodic oxides. The methods involve incorporating an ultraviolet (UV) light absorbing compounds into anodic oxides to prevent color fading of the anodic oxides caused by exposure to UV light. In some embodiments, the UV light absorbing compound includes para-aminobenzoic acid (PABA). The UV light absorbing compound can be incorporated within the anodic oxide during a sealing process. The UV light absorbing compound becomes infused within a seal layer, which is formed during the sealing process. The resultant anodic oxide has a UV light absorbing seal layer that can block UV light from reaching any underlying colorant existing within the anodic oxide.

Abstract: The described embodiments relate to methods and apparatus for increasing rigidity of a metal housing while maintaining or reducing a wall thickness of the metal housing. More particularly a method for embedding a stiffener layer within an aluminum substrate is discussed. In one exemplary embodiment the stiffener layer can be a carbon fiber sheet applied to an inside surface of an unfinished housing and then subsequently covered by depositing a layer of aluminum over the carbon fiber in a solid-state deposition process. The deposited aluminum can adhere to the unfinished housing around or through the carbon fiber layer to bond with the unfinished housing. Deposition parameters can be controlled to prevent damage to the carbon fiber sheet.

Abstract translation: 本文所述的实施方案涉及阳极氧化物和形成阳极氧化物的方法。 该方法包括将紫外线（UV）光吸收化合物并入阳极氧化物，以防止由于暴露于紫外线而导致的阳极氧化物的褪色。 在一些实施方案中，UV光吸收化合物包括对氨基苯甲酸（PABA）。 紫外光吸收化合物可以在密封过程中并入阳极氧化物内。 紫外光吸收化合物注入到在密封过程中形成的密封层中。 所得的阳极氧化物具有UV光吸收密封层，其可以阻挡UV光到达存在于阳极氧化物内的任何底层着色剂。
