Abstract

A housing includes a substrate, a transition layer disposed on the substrate, and a color layer disposed on the transition layer. The transition layer is a mixing coating layer of metal carbonitride. The metal contains titanium and one of which selected from the group consisting of aluminum, chromium, and iron. The color layer is a titanium-chromium-aluminum layer. An electronic device using the housing is also described.

First claim

What is claimed is:

1. A housing, comprising:
a substrate;
a transition layer disposed on the substrate; and
a color layer disposed on the transition layer;
wherein the transition layer is a mixing coating layer of metal carbonitride, the metal comprises titanium and one of which selected from the group consisting of aluminum, chromium, and iron;
wherein the color layer is a titanium-chromium-aluminum layer.

2. The housing as claimed in claim 1 , wherein the transition layer has a thickness of about 1 μm to about 4 μm.

3. The housing as claimed in claim 1 , wherein the color layer comprises titanium having a mass percentage of about 10% to about 15%, chromium having a mass percentage of about 20% to about 35%, and aluminum having a mass percentage of about 50% to about 70%.

4. The housing as claimed in claim 1 , wherein the color layer has a thickness of about 4 μm to about 6 μm.

5. The housing as claimed in claim 1 , wherein the housing further comprises a base layer formed between the substrate and the transition layer, the base layer is a metal layer comprising titanium, chromium, or iron, and has a thickness of about 0.5 μm to about 0.8 μm.

6. The housing as claimed in claim 1 , wherein the substrate is made of aluminum, aluminum alloy, or stainless steel.

7. The housing as claimed in claim 1 , wherein the mixing coating layer of metal carbonitride comprises titanium carbonitride and aluminum carbonitride, titanium carbonitride and chromium carbonitride, or titanium carbonitride and iron carbonitride.

8. The housing as claimed in claim 7 , wherein when the mixing coating layer of metal carbonitride comprises titanium carbonitride and aluminum carbonitride, the titanium carbonitride has a mass percentage of about 60% to about 80%, the aluminum carbonitride has a mass percentage of about 20% to about 40%.

9. The housing as claimed in claim 7 , wherein when the mixing coating layer of metal carbonitride comprises titanium carbonitride and chromium carbonitride, the titanium carbonitride has a mass percentage of about 60% to about 80%, the chromium carbonitride has a mass percentage of about 20% to about 40%.

10. The housing as claimed in claim 7 , wherein when the mixing coating layer of metal carbonitride comprises titanium carbonitride and iron carbonitride, the titanium carbonitride has a mass percentage of about 60% to about 80%, the iron carbonitride has a mass percentage of about 20% to about 40%.

11. An electronic device, comprising:
a main body; and
a housing configured to assemble with the main body, the housing comprising:
