## Abstract

A coating includes a nano-composite layer including a plurality of films. The films are stacked together one after another. Each film includes a zirconium-copper carbonitride layer and a zirconium carbonitride layer.

## Claims

### Claim 1

An article, comprising:
a substrate;
a bonding layer deposited on the substrate; and
a deposited layer disposed on the bonding layer, the bonding layer locating between the substrate and the deposited laver, wherein the deposited layer is a zirconium-copper carbonitride layer, the zirconium-copper carbonitride layer is formed by magnetron sputtering, using a zirconium copper alloy target in which the zirconium has a mass percentage of about 30% to about 70%.

### Claim 2 (depends on 1)

The article as claimed in claim 1, wherein the deposited layer has a thickness ranging from about 0.5 micrometer to about 3 micrometer.

### Claim 3 (depends on 1)

The article as claimed in claim 1, wherein the coating further comprises a color layer covering on the deposited layer.

### Claim 4 (depends on 1)

The article as claimed in claim 1, wherein the substrate is made of high speed steel, hard alloy, or stainless steel.

### Claim 5 (depends on 1)

The article as claimed in claim 1, wherein the bonding layer is a zirconium copper layer, the zirconium copper layer contains zirconium having a mass percentage of about 20% to about 80%, the bonding layer has a thickness ranging from about 0.05 micrometer to about 0.2 micrometer.

### Claim 6 (depends on 1)

The article as claimed in claim 1, wherein the chemical stability of the bonding layer is between the chemical stability of the substrate and the chemical stability of the coating, and the coefficient of thermal expansion of the bonding layer is between the coefficient of thermal expansion of the substrate and the coefficient of thermal expansion of the coating.
