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.
