A foodware article having a multilayer, stick resistant, ceramic coating. Th e foodware article of the present invention includes a metal foodware article (305) having an inner food-contacting surface (310) and an outer surface (315); a bonding layer (320) deposited on the food-contacting surface; and a first layer of (Ti,Al,Cr)N (325) deposited adjacent to the bonding layer. There is optionally a layer of chromium nitride (330) deposited adjacent to the first (Ti,Al,Cr)N layer, and a second layer of (Ti,Al,Cr)N (335) deposit ed on the chromium nitride layer. These layers can be repeated as many times as desired. The (Ti, Al, Cr)N layer is generally the top layer of the multilaye r coating. The coating is stick resistant, scratch resistant, thermally stable , corrosion resistant, and color stable. The foodware is suitable for use with both salty-based and acidic-based foods. A method of making such a foodware article is also disclosed. |
