    Abstract: A surface of aluminiferous metal is brought into contact at 25 to 65 C DEG for 2 to 100 seconds with a surface treatment bath with a pH of 1.0 to 6.0 that contains phosphate ions, dissolved titanium and/or zirconium compounds, dissolved fluorine-containing anions, and a water soluble polymer in the following weight proportions: 1 - 100:1 - 50:1 - 200:1 - 200. This is followed by a water rinse and drying. The water soluble polymer has a chemical structure conforming to formula (I), in which each of X and X represents a hydrogen atom, a C1 to C5 alkyl group, or a C1 to C5 hydroxyalkyl group; each of Y and Y represents a hydrogen atom or a moiety "Z" that conforms to formula (II) or (III), wherein each of R , R , R , R , and R represents a C1 to C10 alkyl group or a C1 to C10 hydroxyalkyl group; the average value for the number of Z moieties substituted on each aromatic ring in the polymer molecules is from 0.2 to 1.0; n is an integer; and the average value of n for the total polymer is from 2 to 50.

    Abstract: Heating an aqueous mixture of a fluoroacid such as H2TiF6 and an oxide, hydroxide, and/or carbonate such as silica produces a clear mixture with long term stability against settling of any solid phase, even when the oxide, hydroxide, or carbonate phase before heating was a dispersed solid with sufficiently large particles to scatter light and make the mixture before heating cloudy. The clear mixture produced by heating can either be mixed with water soluble and/or water dispersible polymers that are polyhydroxyalkylamino-substituted polymers and/or copolymers of p^_-vinyl phenol, or with soluble hexavalent and/or trivalent chromium, to produce a composition that improves the corrosion resistance of metals treated with the composition, especially after subsequent painting.
