Patent ID: 8354008

Claim:
A method for manufacturing a article comprising steps of: providing a substrate; and depositing a color layer on the substrate by magnetron sputtering, wherein the substrate is retained in a vacuum chamber, the temperature in the vacuum chamber is kept between about 50° C. to about 180° C., argon is fed into the vacuum chamber at a flux from about 100 sccm to about 200 sccm, nitrogen is fed into the vacuum at a flux from 50 sccm to 150 sccm, a zirconium target in the vacuum chamber is evaporated at a power from about 5 kW to about 11 kW and a carbon target in the vacuum chamber is evaporated at a power from about 8 kW to about 11 kW, a bias voltage is applied to the substrate is in a range from about −50 volts to about −200 volts for about 10 min to about 60 min, to deposit the color layer on the substrate.
