A foodware article having a multilayer, stick resistant, ceramic coating.
The foodware article of the present invention includes a metal foodware
article having an inner food-contacting surface and an outer surface; a
bonding layer deposited on the food-contacting surface; and a first layer
of (Ti, Al, Cr)N deposited adjacent to the bonding layer. There is
optionally a layer of chromium nitride deposited adjacent to the first
(Ti, Al, Cr)N layer, and a second layer of (Ti, Al, Cr)N deposited 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
multiplayer 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.
