An inorganic paint pigment may include a fluid matrix, and paint flakes carried within the fluid matrix. Each paint flake may include a common aluminum layer having a first major surface and a second major surface opposing the first major surface, a first plasmonic aluminum reflector layer carried by the first major surface, and a second plasmonic aluminum reflector layer carried by the second major surface.

The invention relates to a high-frequency-transparent component comprising: a main body (2) and a coating (3) consisting of metal-doped Al2O3 sputtered thereon, and to a method for producing said component.

A coated member, an electronic device, and a method for manufacturing the coated member are provided. The coated member comprises a substrate, a color layer formed on a surface of the substrate, and an interference layer formed on a surface of the color layer. A coordinate L* corresponding to a color space presented by the color layer in a CIE LAB color system is within a preset range. When the coordinates of L* are within the preset range, the color of the coated member may be the same or may be different from the color of the color layer. Light passes through the interference layer and then enters the color layer. The color layer reflects and refracts the light. The reflected light enters the interference layer. The interference layer interferes with the reflected light, so that the coated member appears to be a target color.

A method of making a decorative article (1) such as a jewellery piece, the article comprising a body (2) having a decorative layer (5) and an element (3) set into the body. The method comprises: providing an element that is at least partially coated with a removable layer (4), setting the element into the body, coating the element and the body with the decorative layer, and removing the removable layer and the decorative layer from the element.

A component for a processing chamber includes a ceramic body having at least one surface with a first average surface roughness. The component further includes a conformal protective layer on at least one surface of the ceramic body, wherein the conformal protective layer is a plasma resistant rare earth oxide film having a substantially uniform thickness of less than 300 μm over the at least one surface and having a second average surface roughness that is less than the first average surface roughness.

To provide a decorative member having a cherry blossom pink color. A cherry blossom pink decorative member of the present invention includes a base and a decorative coating formed on the base, wherein the decorative coating is formed by layering an undercoat layer and a finishing layer from the base side, the undercoat layer is a carbonitride layer composed of a carbonitride of a metal containing Ti and at least one selected from Nb and Ta, and the finishing layer is a Au alloy layer composed of an alloy containing Au, a metal having a silver color, and Cu.

This application relates to a portable electronic device. The portable electronic device includes an enclosure having a metal oxide coating, the metal oxide coating including a metal alloy substrate that is doped with a dopant, and a metal oxide layer overlaying and formed from the metal alloy substrate so that the metal oxide layer includes the dopant.

A method of forming a surface coating on a component of an electronic device can include depositing an aluminum layer including at least about 0.05 weight percent (wt %) of a grain refiner on a surface of the component by a physical vapor deposition process, and anodizing the aluminum layer to form an anodized aluminum oxide layer having a L* value greater than about 85 in the CIELAB color space.

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.

A stretchable reflective color-shifting film comprises a stretchable transparent polymer layer; a semi-transmissive metal layer; a transparent spacer layer; a reflective metal layer; an adhesive layer; and a stretchable base film layer. When the film body is stretched by 25%, the peak total reflectance stretched is at 80% of the peak total reflectance when the film body is unstretched according to the Total Reflectivity Test.
