  • Patent number: 8142841
    Abstract: Methods for deoxidizing metallic surfaces are disclosed. Such a method may include contacting a surface of a metal strip with one or more chemical solutions until a potential drop across a thickness of the metal strip is less than a pre-selected value. To process a metal strip such that it may be suitable for fabrication of a bipolar plate for use in a fuel cell, the metal strip may be processed until the potential drop is less then about 15 mV. A surface of the metal strip may be contacted for a first period of time with a first chemical solution having a pH of between 10 and 14. Thereafter, the surface may be contacted for a second period of time with a second chemical solution having a pH of between 1 and 3. A conductive organic coating may then be applied to the surface. Such methods are particularly suitable for use in connection with a coil coating process.

  • Patent number: 5584944
    Abstract: A lubricant and surface conditioner for formed metal surfaces, particularly aluminum and tin beverage containers, reduces the coefficient of static friction of said metal surfaces and enables drying said metal surfaces at a lower temperature. The conditioner includes a water-soluble organic material selected from amine oxides and quaternary ammonium salts, fluozirconate, fluohafnate, or fluotitanate ion, and preferably also phosphate and nitrate ions. Good resistance to damaging the friction reducing effect by overheating and to staining of the domes of treated containers during pasteurization can be achieved.

  • Patent number: 5584943
    Abstract: A lubricant and surface conditioner for formed metal surfaces, particularly beverage containers, reduces the coefficient of static friction of said metal surfaces and enables drying said metal surfaces at a lower temperature. An aqueous composition for forming the conditioner by contact with metal surfaces includes a water-soluble organic material selected from a phosphate ester, alcohol, fatty acid including mono-, di-, tri-, and polyacids; fatty acid derivatives such as salts, hydroxy acids, amides, esters, ethers and derivatives thereof; and mixtures thereof and at least one of the elements selected from zirconium, titanium, cerium, aluminum, iron, tin, vanadium, tantalum, niobium, molybdenum, tungsten, and hafnium in metallic or ionic form. In order to avoid formation of sludge in the aqueous lubricant and surface conditioner forming composition, the composition should contain as little as possible of materials containing phenanthrene rings, such as conventional surfactants made by ethoxylating rosin.

  • Patent number: 5486316
    Abstract: The coefficient of friction of aluminum can surfaces after alkaline cleaning and drying can be substantially reduced by adding to the alkaline cleaner a mobility enhancing additive, preferably a surface active quaternary ammonium salt with hydroxyethyl substituents on the quaternary nitrogen atoms. A can surface suitable for automatic conveying and high quality lacquer or printing ink adhesion can thereby be obtained, if desired without including any substantial fluoride content in any treatment stage.

  • Patent number: 4273592
    Abstract: An acidic aqueous coating solution for forming a coating on an aluminum surface which is corrosion resistant and to which overlying coatings adhere excellently. The coating solution contains a zirconium and/or hafnium compound, a fluoride compound, and a polyhydroxy compound having no more than 7 carbon atoms. The coating solution is capable of forming on an aluminum surface a uniformly colorless and clear coating so that the coated surface has the appearance of the underlying metal surface, that is, the coating can be formed without changing the appearance of the metal surface. When coating a bright shiny aluminum surface, there can be produced a coated surface having a uniformly bright shiny appearance which is maintained even after the coated surface is subjected to boiling water. Such surface is capable of undergoing the "muffle test" to confirm the presence of the clear and colorless coating.
