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.
Claims15
A method of manufacturing, comprising:
- oxidizing, using plasma, a first surface of a substrate comprising a metal-material;
- 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;
- and
- 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.
A method of manufactory comprising:
- making a portion of a housing of an electronic device having an electrical circuit wherein the making comprises:
- oxidizing, using micro-arc oxidation, a first surface of a substrate comprising a metal-material;
- cutting, using diamond 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;
- and
- disposing, using electrophoretic deposition, a coating layer over the exposed second surface to form the portion having the oxidized first surface and the coated second surface;
- and
- assembling the electrical circuit with the housing, the housing external to the electrical circuit.
An electronic device, comprising:
- an electrical circuit;
- and
- a housing external to the electrical circuit, a portion of the housing comprising a substrate having;
- a core layer comprising a metal material;
- an oxide layer disposed over a first surface of the core layer, the oxide is a micro-arc oxide of the metal material;
- and
- a functional coating disposed over the oxide layer, the functional coating comprising a polymer;
- an edge of the substrate having a non-oxidized second surface not parallel to the first surface, the second surface cut by diamond cutting and having thereon an electrophoretically deposited coating layer comprising at least one of polyacrylic, epoxy, and nanoparticles.
