Abstract
This application provides a method of manufacturing a case, a case and an electronic device. This method may include providing a metal case with a surface; applying a first oxidation treatment on the surface of the metal case to form a first oxidation layer; defining a first area on the surface; removing a portion of the first oxidation layer located within the first area; applying a second oxidation treatment on the surface within the first area to form a second oxidation layer, and forming a paint layer on the second oxidation layer by spraying.
Claims20
A method of manufacturing a case to be used in electronic devices, comprising:
- providing a metal case with a surface;
- applying the first oxidation treatment on the surface of the metal case to form a first oxidation layer;
- defining a first area on the surface of the metal case;
- removing a portion of the first oxidation layer located within the first area;
- applying the second oxidation treatment on the surface of the metal case within the first area to form a second oxidation layer, and
- forming a paint layer on the second oxidation layer by spraying.
A case for electronic device, comprising:
- a metal substrate;
- a first oxidation layer set on a portion of the metal substrate and at a side of the metal substrate;
- a second oxidation layer set on another portion of the metal substrate and at the same side of the metal substrate as the first oxidation layer;
- and
- a paint layer set on the second oxidation layer and covering the second oxidation layer.
An electronic device with a case, wherein the case comprises:
- a metal substrate;
- a first oxidation layer set on a portion of the metal substrate and at a side of the metal substrate;
- a second oxidation layer set on another portion of the metal substrate and at the same side of the metal substrate as the first oxidation layer;
- and
- a paint layer set on the second oxidation layer and covering the second oxidation layer.
