    摘要: Composition and process for treating aluminum, aluminum alloys and anodized aluminum substrates to improve the corrosion resistance and adhesive bonding strength of the aluminum substrates. The process comprises pre- or post-treating said aluminum with an acidic aqueous solution comprising, per liter of solution, from about 0.1 to 22 grams of at least one fluorometallate, about 0.1 gram up to the solubility limit of a water soluble cationic or divalent zinc compound and, optionally, effective amounts of water soluble thickeners and/or surfactants.
