Abstract: An electronic device may be provided with conductive structures such as a titanium housing wall. A visible-light-reflecting coating may be formed on the titanium housing wall. The coating may have adhesion and transition layers and an uppermost opaque coloring layer. In a first example, the uppermost opaque coloring layer includes CrC on a CrSiN transition layer. In a second example, the uppermost opaque coloring layer includes CrN on a CrN transition layer. The coating may exhibit a relatively uniform metallic silver or gray color that is smudge resistant even when the underlying titanium housing wall has a three-dimensional shape.

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.

The color may be relatively stable even if the thickness of the coating varies across its area.

Abstract: An electronic device such as a wristwatch may include a conductive housing. A corrosion-resistant coating may be deposited on the conductive housing. The coating may include transition layers and an uppermost alloy layer. The transition layers may include a chromium seed layer on the conductive housing and a chromium nitride layer on the chromium seed layer. The uppermost alloy layer may include TiCrCN or other alloys and may provide the coating with desired optical reflection and absorption characteristics. The transition layers may include a minimal number of coating defects, thereby eliminating potential sites at which visible defects could form when exposed to salt water. This may allow the electronic device to exhibit a desired color and to be submerged in salt water without producing undesirable visible defects on the conductive housing structures.

Abstract: Electrical contacts are described. An electrical contact can be formed on an exterior surface of a housing of an electronic device and can be cosmetically similar to the exterior surface. For example, the electrical contact can include a conductive plug inserted through an opening in a wall of the housing. A metallic coating can be applied to an outward-facing end of the conductive plug and fill up an outer portion of the opening until the metallic coating is about flush with the exterior surface of the housing. Properties of the metallic coating can be selected to closely match a color and a texture of the housing.

Abstract: The disclosure is directed to treated titanium alloys comprising a titanium substrate coated with an oxidized surface coating or an oxide-interdiffused titanium substrate. By creating an oxidized surface coating or oxide-interdiffused titanium substrate at the titanium substrate surface, the resulting treated titanium alloy has a dark color (e.g., grey to black).

Abstract: An electronic device may be provided with conductive structures such as conductive housing structures. A visible-light-reflecting coating may be formed on the conductive structures. The coating may have adhesion and transition layers and a thin-film interference filter on the adhesion and transition layers. The thin-film interference filter may be a four-layer interference filter stacked directly onto the adhesion and transition layers and having an uppermost SiCrN layer, a lowermost SiN layer, and interleaved SiH and SiN layers. If desired, an opaque coloring layer such as a Cr layer may be disposed between the interference filter and the adhesion and transition layers. The coating may exhibit a deep red or orange color that has a relatively uniform visual response even when the underlying conductive structures have a three-dimensional shape.

Abstract: An electronic device may have a housing. The device may include metal structures such as a metal member forming a portion of the housing, a portion of a strap, or other portions of the device. A gold-containing coating such as a layer of elemental gold or a gold alloy may cover the metal member to provide the metal member with a gold appearance or other desired appearance. To protect the metal member and the gold-containing coating, the metal member and gold-containing coating may be covered with a protective coating layer such as an organic protective layer. The organic protective layer may have a fluoropolymer layer with thiol coupling groups to promote adhesion to the gold-containing layer or may contain a polymer layer with silane and thiol coupling groups that serves as an adhesion promotion layer for an overlapping fluoropolymer layer with silane coupling groups.
