Abstract:
One example provides a method of manufacturing. The method comprises oxidizing, using plasma, a first surface of a substrate comprising a metal-material. The method further comprises cutting into the substrate through the oxidized first surface to expose a non-oxidized second surface of the substrate, the second surface not parallel to the first surface. The method further comprises disposing, using electrophoretic deposition, a coating layer over the exposed second surface to form an article having the oxidized first surface and the coated second surface.
Abstract:
A housing for an electronic device is described. The housing comprises a substrate, which comprises a magnesium alloy. The substrate has a first coated surface and a second coated surface. The first coated surface comprises an oxidized layer or at least one coating layer. The second coated surface comprises a layer coated on a non-oxidized surface of the substrate. The layer comprises (i) a chelating agent and a metal ion or a chelated metal complex thereof, or (ii) a sol-gel coating or a sol-gel hybrid coating.
Abstract:
A multi-layered metal includes a first layer, and a second layer on the first layer. The second layer is bonded to the first layer, by applying at least one of heat and pressure to an assembly including the first layer and the sheet to cause inter-metal diffusion between the first layer and the second layer.
Abstract:
A housing for an electronic device is described. The housing comprises a substrate. The substrate comprises a magnesium alloy. An electrophoretic polymer layer overlies 5 the substrate. A coating layer is positioned between the substrate and the electrophoretic polymer layer. The coating layer comprises (i) a layer comprising a chelating agent and a metal ion or chelated metal complex thereof, (ii) a passivation layer or (iii) a passivation layer and a layer comprising a chelating agent and a metal ion or chelated metal complex thereof.

Abstract:
A magnesium alloy layered composite for an electronic device can include a magnesium alloy substrate, a passivation layer positioned on the magnesium alloy substrate, and a sol-gel layer positioned on the passivation layer. The passivation layer can include a molybdate, a vanadate, a phosphate, a chromate, a stannate, or a manganese salt. The sol-gel layer can include a silicate, a silane, a siloxane, or a metal C1-C5 alkoxide.
Abstract:
In an example, techniques of waterborne emulsion based electroplating of magnesium substrates are described. In an example method, the magnesium substrate is electroplated with a layer of first metal, in a mixture of a non-aqueous ionic solution and a waterborne emulsion. The waterborne emulsion releases ions of the first metal in the non-aqueous ionic solution.
Abstract:
The present disclosure is drawn to a coated substrate for an electronic device, and can include a substrate for housing or support electronic components, a primer layer on the substrate, and a ceramo-metallic layer on the primer layer. The ceramo-metallic layer can include a composite of ceramic particles in an amount of about 3 wt% to about 15 wt%, reflective metal particles in an amount of about 0.1 wt% to about 2 wt%, and polymer binder in an amount of about 70 wt% to about 97 wt%, with the ceramo-metallic layer weight percentages based on dry weight.
