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, CrSiCN or CrSiC. 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 in the visible spectrum (e.g., at blue or purple wavelengths). 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: 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, an opaque coloring layer on the adhesion and transition layers, and a three-layer thin-film interference filter on the opaque coloring layer. The three-layer thin-film interference filter may have an uppermost SiC layer, a lowermost SiCrCN layer, and a CrC layer interposed between the SiC layer and the SiCrCN layer. The opaque color layer may be a CrSiCN layer. The coating may exhibit a light violet color that has a relatively uniform visual response even when the underlying conductive structures have a three-dimensional shape.

Abstract: An electronic device may include conductive structures such as conductive housing structures. A high-brightness, visible-light-reflecting coating may be formed on the conductive structures. The coating may have adhesion and transition layers and an uppermost coloring layer on the adhesion and transition layers. At least the uppermost coloring layer may be deposited using a high impulse magnetron sputtering (HiPIMS) process. The uppermost coloring layer may include a TiCrN film, a TiCrCN film, a TiCN film, or a metal nitride film that contains Ti, Zr, Hf, or Cr. The coating may exhibit a high-brightness gold color.

Abstract: An electronic device can include a housing, a display positioned within the housing; and a cover glass disposed over the display and attached to the housing. The cover glass can include a glass sheet; a hard coat layer disposed on the glass sheet, having a hardness greater than a hardness of the glass sheet; and a gradient layer deposited on the hard coat layer and having a composition that transitions from a first composition at the hard coat layer to a second composition at a top surface of the gradient layer. The first composition can be predominantly a composition of the hard coat layer and the second composition is different than the first composition. The second composition can be predominantly SiO2. The hard coat layer can include SiON. The cover glass can include an intermediate gradient layer disposed between the glass sheet and the hard coat layer.

Abstract: An electronic device can include a housing, a display positioned within the housing; and a cover glass disposed over the display and attached to the housing. The cover glass can include a glass sheet; an intermediate hard-coat layer disposed on the glass sheet, having a hardness greater than a hardness of the glass sheet; an interference layer deposited on the intermediate hard-coat layer and having at least two layers with different optical constants and/or thicknesses; and an exterior hard-coat layer deposited on the interference layer. The optical constants and/or thicknesses of the interference layer can be selected based on an optical constant and/or thickness of the exterior hard-coat layer do minimize reflection of the cover glass.
