Abstract:
Composition and process for coating ferrous alloys to improve the corrosion resistance and adhesive bonding strength of the alloys. The process comprises using the composition for treating the ferrous alloys such as steel with an acidic aqueous solution comprising, per liter of solution, from about 0.1 to 22 grams of hexafluorozirconates, effective amounts of at least one water soluble divalent zinc compound, and 0.0 to 10 grams of water soluble thickeners and/or water soluble surfactants.
