Abstract: Electronic devices comprising a substrate at least partially enclosed by an energy absorbing material are disclosed herein. The energy absorbing material can integrally or removably attach to the substrate. The substrate can be carbon fiber, glass, ceramic, metal, composite, or mixtures thereof. The energy absorbing material can comprise at least one thermoplastic polymer.

Abstract: Various examples provide a method of making a hydrophobic surface for an object. According to the method, a hydrophobic coating may be applied to an original surface of the object. A microstructure may be formed on the original surface of the object. The hydrophobic surface of the object may be obtained with the microstructure submerged by the hydrophobic coating. The microstructure may be a rough structure including micro-sired portions, and may have greater hardness than the hydrophobic coating.

Abstract: The present subject matter relates to patterned substrates. In an example implementation of the present subject matter, techniques for creating patterns on different substrates are described. In an example, a method of creating the patterns includes spray depositing a plurality of coating layers over the substrate to form a coated substrate, where the plurality of coating layers include at least a top layer, and at least one of a base coating layer, a primer coating layer, and a powder coating layer. The method further includes forming a predefined pattern on the coated substrate by one of laser etching and Computer Numeric Control (CNC) process.

Abstract: Examples relating to coating an alloy substrate are described. For example, techniques for coating a surface of the alloy substrate with a coating layer and an exterior coat include anodizing an alloy substrate to form a metal oxide layer on surface of the alloy substrate and obtain an anodized alloy substrate. The alloy substrate is a metal alloy and the anodized alloy substrate has irregularities on surface. Thereafter, a coating layer is applied on the surface of the alloy substrate to smoothen the surface by providing a uniform covering on the irregularities of the surface. After applying the coating layer, an exterior coat is deposited on the surface of the alloy substrate.

Abstract: Examples of a cover for a device are described herein. The cover includes a substrate to be placed in proximity of a heat source of a device. In an example, a heat resistant layer is applied over a surface of the substrate to insulate heat generated by the heat source. Further, a top layer is applied over one of the heat resistant layer and another surface of the substrate, which is opposite to the surface having the heat resistant layer. The top layer provides at least one of chemical resistant properties and aesthetic properties.

Abstract: Provided in one examole hod of manufacturing. The method includes disposing over at least a portion of a substrate a first layer, the substrate comprising a metal material and the first layer comprising a water-borne primer. The method includes disposing over at least a portion of the first layer a second layer, the second layer comprising a water-borne basecoat material. The method includes disposing over at least a portion of the second layer a third layer, the third layer comprising a water-bome topcoat material.
