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.

Abstract: An electronic device may include conductive structures having a visible-light-reflecting coating. The coating may include a seed layer, transition layers, a neutral-color base layer, and an uppermost layer that forms a single-layer interference film. The neutral-color base layer may be opaque to visible light. The interference film may include silicon and may have an absorption coefficient between 0 and 1. The interference film may include, for example, CrSiN or CrSiCN. The composition of the interference film, the thickness of the interference film, and/or the composition of the base layer may be selected to provide the coating with a desired color near the middle of the visible spectrum (e.g., at green wavelengths). The color may be relatively stable even if the thickness of the coating varies across its area.

Abstract: An electronic device may include conductive structures with a light-reflecting coating. The coating may have a two or four-layer thin-film interference filter. The two-layer filter may have a CrN layer and an SiCrN layer. The four-layer filter may have two CrN layers and two SiCrN layers. The two-layer filter may be used to coat relatively small conductive components. The four-layer filter may be used to coat a conductive housing sidewall. Both types of interference filter may produce a relatively uniform light blue color despite variations in coating thickness produced on account of the geometry of the underlying conductive structure.

Abstract: This application relates to a method for forming an enclosure for a portable electronic device, the enclosure including a metal substrate that is overlaid by an anodized layer. The method includes dyeing the anodized layer by exposing pores of the anodized layer to a dye. The method further includes sealing the dye within the pores by exposing the anodized layer to a zinc-based sealing solution, where an external surface of the anodized layer having the pores that are sealed includes an amount of zinc between about 3 wt % to about 6 wt %.

Abstract: This application relates to an enclosure for a portable electronic device. The enclosure includes a titanium substrate having a textured surface that includes randomly distributed peaks separated from each other by valleys, where tops of the peaks are separated from bottoms of the valleys by at least a minimum separation distance such that the textured surface is characterized as having an Sq (root mean square height) that is greater than 0.3 micrometers.
