1. A coated article, comprising:
a substrate; a composite layer formed on the substrate; and a chromium-oxygen-nitrogen layer formed on the composite layer, wherein the composite layer comprises an equal number of alternating nickel-aluminum-holmium layers and iridium layers, one of the nickel-aluminum-holmium layers is directly formed on the substrate, one of the iridium layers directly bonds to the chromium-oxygen-nitrogen layer; and where the composite layer comprises two or more nickel-aluminum-holmium layers and two or more iridium layers.
