Preferably the amount of aqueous composition used is such as to produce a chromium add-on of from 20-160 mg/m.sup.2.

摘要： The invention involves a nonrinse type hydrophilic surface-treating process capable of imparting hydrophilicity to the surface of a metal material, e.g., aluminum, and, at the same time, forming thereon a coating excelling in resistance to corrosion. In the process there is applied an aqueous solution which contains selected amounts of Cr ions (III, VI), F.sup.-, SiO.sub.2 and a water-soluble acrylic acid polymer, and optionally PO.sub.4.sup.-3, if necessary. An aluminum article treated by this process is suitable for the fins of a heat exchanger.

摘要： A method of producing highly corrosion-resistant surface-treated steel plates where Cr elusion is small in spite of drying at low temperatures and corrosion resistance is excellent. In a process for producing surface treated steels where Zn type plated steels are treated through (i) chromate treatment, (ii) coating a resin composition and (iii) baking treatment, zirconium fluoride ion and Zn ion of appropriate amounts are added into the chromate bath, and Cr.sup.6+ /Cr.sup.3+ ratio in the bath is controlled to be low. Further the resin composition to be coated after the chromate treatment is rendered a solvent type resin composition obtained by adding silica and/or sparingly water soluble Cr compound to basic epoxy resin.
