摘要： A twice-anodized aluminum substrate is anodized sequentially in first and second aqueous electrolytes. In the first, the substrate is conventionally anodized to produce (i) a porous anodic oxide layer having open pores and a passivation layer thereunder. The substrate, now singly-coated, is then anodized in the second electrolyte of an aqueous solution of an organophosphorus compound which generates a residue which is chemisorbed and covalently bonded to the substrate to form (ii) a monomolecular essentially continuous monolayer on the outer surface of (i), and at the same time, the second anodizing step produces (iii) a barrier layer of non-porous aluminum oxide under (i). The thickness of this barrier layer can be increased as a function of the voltage used while maintaining the thickness of (i) substantially constant, and (ii) protects (i) from dissolution. Depending upon the choice of the organophosphorus compound, a hydrophobic, or chemically resistant surface may be produced; or, a surface which provides a leaving group to be reacted with an appropriate organic coating to be applied after the triplex layer is formed.

摘要： Disclosed is a method of producing a functionalized layer and an aluminum hydroxide layer on an aluminum substrate, the aluminum hydroxide layer located between the substrate and the functionalized layer. The method comprises the steps of subjecting an aluminum substrate to a hydrothermal treatment in an aqueous solution having a pH in the range of 2 to 14 to form a layer of aluminum hydroxide on said substrate and thereafter treating said aluminum substrate with a phosphorus-containing acid selected from phosphonic and phosphonic acid to form a functionalized layer on said aluminum hydroxide layer, the functionalized layer comprised of the reaction product of said acid and the layer of aluminum hydroxide.

摘要： Disclosed is a process for anodically oxidizing aluminum alloy surfaces as a pretreatment for structural adhesive bonds or laminates. The process is comprised of anodically oxidizing aluminum and its alloys in phosphorous acid containing electrolyte to form a porous film comprised of Al, O and P. This film provides a very effective substrate for adhesively bonding aluminum articles and laminates.

摘要： A process is disclosed for treating the surface of a valve metal such as aluminum to form a two layer protective coating thereon using an anodizing bath consisting essentially of an aqueous solution having a concentration ranging from about 0.001 molar to a saturated solution of a monomeric phosphorus- containing compound selected from the class consisting of a 1-30 carbon water soluble phosphonic acid, a 1-30 carbon water soluble phosphinic acid, and mixtures thereof. The valve metal surface is anodized in the anodizing bath while maintaining a voltage selected from a range of from about 1 to about 400 volts until the current density falls to a level indicative of the fact that a nonporous valve oxide layer has been formed on the valve metal surface and a reaction product from the monomeric phosphonic/phosphinic acid compound is chemically bonded to the oxide layer.

摘要： A laminate suitable for vehicular applications includes at least two sheets of aluminum alloy and an adhesive layer between the sheets bonding them together. An oxide layer on surfaces of the sheets is treated with a phosphorous acid electrolyte, so that a coordination number of four predominates for the aluminum-oxygen-phosphorous bond. Equivalent bonding strengths in the laminates are obtained in substantially less time with phosphorous acid treatment compared with phosphoric acid treatment.
