A coated article is described. The coated article includes a substrate, a bonding layer formed on the substrate, a plurality of nickel-chromium-nitrogen layers and a plurality of copper-cerium alloy layers formed on the bonding layer. The bonding layer is a nickel-chromium layer. Each nickel-chromium-nitrogen layer interleaves with one copper-cerium alloy layer. One of the nickel-chromium-nitrogen layers is directly formed on the bonding layer. A method for making the coated article is also described.
