Abstract
A home appliance chemically resistant to peroxide degradation. The home appliance includes a metal substrate disposed therein that includes a metal substrate having a bulk portion and a coating layer contacting a surface of the bulk portion. The coating layer includes a ternary metal oxide compound, a metal alloy, an intermetallic compound, or a combination thereof. The ternary metal oxide compound, the metal alloy or the intermetallic compound is (a) unreactive with hydrogen peroxide or (b)(1) reactive with hydrogen peroxide to form one or more metal oxides unreactive with hydrogen peroxide or reactive with hydrogen peroxide to form one or more metal oxides unreactive with hydrogen peroxide and/or (b)(2) reactive with hydrogen peroxide to form one or more elemental metals reactive with hydrogen peroxide to form one or more metal oxides.
