The present invention relates to metals or metal alloys comprising a protective silicate glass-like coating, and methods for coating the metals or metal alloys. The methods comprise removal of any existing oxide layer from the metal or metal alloy, formation of a new oxide layer on the metal or metal alloy using chemical passivation or exposure to a gaseous oxidising environment, coating the oxidised metal or metal alloy with an aqueous silicate solution, and curing the coating.

A crystalline titanium and magnesium compound having an X-ray diffraction pattern having interplanar spacing (d-spacing) values at about 5.94, 3.10, 2.97, 2.10, 1.98, 1.82, and 1.74±0.1 angstroms may be used in protective coatings for metal or metal alloy substrates. The coatings exhibit excellent corrosion resistances and provide corrosion protection equal to or better than typical non-chromate coatings.

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 unreactive with hydrogen peroxide.
