Claim Text:
1. An aluminum alloy powder-pigment prepared in an atmosphere selected from the group consisting of oxygen, nitrogen/inert gas and nitrogen-hydrogen and having a particle size ranging from about 2 to 100 microns; said aluminum alloy powder-pigment having the formula Aluminum-X—Y wherein X is an element selected from the group consisting of zinc, cadmium, magnesium, barium and manganese, and Y is an element selected from the group consisting of indium, gallium, tin, and bismuth; said aluminum alloy powder-pigment coated with an effective amount of semi-conducting corrosion-inhibitor derived from an acidic aqueous solution consisting essentially of, in parts by weight, from about 0.01 to 22 parts of a trivalent chromium compound, from about 0.01 to 12 parts of a hexafluorozirconate, from about 0.01 to 12 parts of at least one fluorometallate selected from the group consisting of tetrafluoroborates, hexafluorosilicates, and hexafluorotitanates, from about 0.01 to 12 parts of at least one divalent zinc compound, from about 0.01 to 5 parts by weight of water soluble corrosion inhibitor, and an effective amount of at least one stabilizing compound selected from the group consisting of carboxylic compounds, polyhydroxy compounds and mixtures of said compounds.
