  • Surface treatment of aluminum and its alloys
    Patent number: 4650525
    Abstract: A composition and process useful in forming films on the surface of aluminum or its alloys is disclosed. The composition is an aqueous solution containing an alkali metal, silicon, fluorine, zinc and iron. The film is an adherent hydrophilic corrosion resistant film useful as such and/or as a lubricating film in metal forming.

  • Process for treating the surfaces of aluminum heat exchangers
    Patent number: 4421789
    Abstract: A method for the treatment of aluminum surfaces to provide them with a corrosion resistant, hydrophilic coating. The aluminum surfaces are first provided with a corrosion-resistant film and, thereafter, a coating of fine silica particles is applied to the corrosion resistant film. Suitable corrosion resistant films which may be used are anodized films, boehmite films, chromated films and organic resin films. The coated aluminum surfaces produced by this method are found to have particular application for aluminum heat exchangers.

  • Process for treating an aluminum surface
    Patent number: 4136073
    Abstract: Disclosed is a composition and process useful for improving the corrosion resistance and/or paint adhesion of an aluminum surface. The composition is an aqueous acidic one containing an organic film-forming polymer and a titanium compound in a weight ratio of polymer : Ti of 100 : 1 to 1 : 10. The aluminum surface is contacted with the composition at a temperature not in excess of 70.degree. C.
