The present subject matter relates to Nickel-free (Ni-free) sealing of anodized metal substrates. In an example mentation of the present subject matter, an anodized metal substrate is disposed with a first layer of a Ni-free sealing material over a surface of the anodized metal substrate. Further, a second layer of a second sealing material is disposed atop the first layer to sandwich the first layer of Ni-free sealing material between the surface of the anodized metal substrate and the second layer, to form a sealed metal substrate.

Nickel-free sealing of anodized metal substrates

The application discloses examples of a device housing of an electronic device including a magnesium-alloy substrate. The device housing further including a treatment layer applied over the magnesium-alloy substrate and a metallic coating layer applied over the treatment layer to provide a metallic luster. Further, a paint coating layer is disposed over a first portion of the metallic coating layer. Further, a top coating layer is applied over the paint coating layer and a visible second portion of the metallic coating layer.

Device housing with metallic luster

The present disclosure is drawn to covers for electronic devices. In one example, a cover for an electronic device can include an aluminum or aluminum alloy cover frame having an opening. A magnesium or magnesium alloy cover panel supported by the aluminum or aluminum alloy cover frame within or over the opening. A protective coating can be over a surface of the aluminum or aluminum alloy cover frame and a surface of the magnesium or magnesium alloy cover panel. A chamfered edge can include a chamfer at an edge of the aluminum or aluminum alloy cover frame. The chamfer can expose the aluminum or aluminum alloy cover frame beneath the protective coating, and the chamfer at the same time does not expose the magnesium or magnesium alloy cover panel.

Covers for electronic devices

In one example, a device housing is described, which may include a base substrate and ion-exchanged glass beads disposed on an outer surface of the base substrate.

Device housings with glass beads

Examples of shutter assembly are described herein. In an example, the shutter assembly includes an opening having a magnetic rubber-based shutter disposed in the opening. The magnetic rubber-based shutter is slidable along a length of the opening to selectively cover and expose the camera.

Shutter assemblies for electronic devices

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.

Cover for devices

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.
