    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： This invention relates to the use of sodium nitroferricyanide as a substitute for sodium or potassium ferricyanide in nitric acid acidified, hexavalent chromium-fluoride solutions for the treatment of aluminum and its alloys (wherein aluminum is the principal constituent), providing coatings having excellent corrosion-resistance, reduced surface powdering, and improved adhesion and appearance. Small amounts of sodium vanadate may also be added to effectively modify the characteristics of the deposited coatings. Controlled build-up of the protective coatings, produced by chemical reaction between the active components of the solution and the aluminum or aluminum alloy surfaces, are readily accomplished within a temperature range of 65.degree.-85.degree. F. and an immersion time of 5-10 minutes.
