Abstract
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.
