Abstract

A housing includes a substrate and a nano-composite layer deposited on the substrate. The nano-composite layer includes a number of metal oxide nitride layers and a number of Ce layers. Each metal oxide nitride layer alternates with a Ce layer, and the outermost nano-composite layer is a metal oxide nitride layer. The metal in the metal oxide nitride layer aluminum, titanium, silicon, chromium, or zirconium.

Claims

1. A housing, comprising:

a substrate; and

a nano-composite layer deposited on the substrate, the nano-composite layer comprising a number of metal oxide nitride layers and an equal number of Ce layers, and each metal oxide nitride layer alternating with a Ce layer, wherein the Ce layer consists of Ce, the outermost layer of the nano-composite layer being a metal oxide nitride layer;

wherein metal in the metal oxide nitride layer is a selected from a group consisting of aluminum, titanium, chromium and zirconium.

2. The housing as claimed in claim 1, wherein the substrate is made of metallic element.

3. The housing as claimed in claim 2, wherein the metallic element is selected from an aluminum, aluminum alloy, magnesium and magnesium alloy.

4. The housing as claimed in claim 1, wherein the layer of the nano-composite layer contacting with the substrate is a Ce layer.

5. The housing as claimed in claim 1, wherein the metal oxide nitride layers and the Ce layers are deposited by magnetron sputtering.

6. The housing as claimed in claim 1, wherein the nano-composite layer has a thickness ranging from about 1 μ

m to about 3 μ

ms.

7. The housing as claimed in claim 1, wherein the number of metal oxide nitride layers and the number of Ce layers is each about 6˜

30.

8. The housing as claimed in claim 1, wherein an atomic nitrogen content and an atomic oxygen content in each metal oxide nitride layers is the same.

9. The housing as claimed in claim 1, wherein an atomic nitrogen content and an atomic oxygen content in metal oxide nitride layers are each gradually increased from near the substrate to away from the substrate.

10. The housing as claimed in claim 1, wherein a cerium-oxide layer is formed between each metal oxide nitride layer and nearest Ce layer.
