  • Patent number: 5667599
    Abstract: A process for producing a black oxide coating on an aluminum or aluminum alloy component in which the process entails a single treatment step with a novel solution to rapidly produce the desired black oxide coating. The process includes cleaning the surface to be coated and then, without first undergoing anodization, treating the surface with a solution that develops a black oxide on the surface. The reactive component of the solution comprises distilled water containing chlorides, sulfates and bicarbonates of sodium salts. The remainder of the solution includes a catalyst and a substance for maintaining the pH of the solution at a level sufficient to promote the reaction between the surface of the aluminum alloy and the reactive constituents.

  • Patent number: 5460895
    Abstract: An improved aluminum alloy stock material is provided for use in a tubeplate-and-center type evaporator within an automobile air conditioning system. The improved aluminum alloy stock contains a unique aluminum alloy core material which is clad on both sides with an appropriate aluminum-silicon brazing alloy. The inventive aluminum alloy core material is characterized by the presence of boron in amounts sufficient to inhibit the formation of copper-rich precipitates in the grain boundaries of the alloy, so as to enhance the ability of the alloy to resist intergranular corrosion. The alloy is also characterized by a higher copper concentration and lower manganese and titanium concentrations as compared to conventional aluminum alloys used in these types of aluminum alloys.

  • Patent number: 5377901
    Abstract: A method is provided for enhancing the corrosion resistance of a 3000 series aluminum alloy. In particular, the method encompasses processing steps which promote corrosion resistance of brazed assemblies, such as tubeplate-and-center type evaporator units for automobile air conditioning systems. The method is directed at virtually eliminating the precipitation of CuAl.sub.2 particles in the grain boundaries of a 3000 series aluminum alloy, such that evaporator units formed from such an alloy are characterized by enhanced and more consistent corrosion resistance, as well as improved mechanical properties. The primary processing step involves rapidly cooling the evaporator unit after brazing so as to maintain the copper present in the 3000 series aluminum alloy in solid solution. In addition, the reheat and annealing steps are preferably controlled so as to avoid the formation of CuAl.sub.2 particles prior to brazing.

  • Patent number: 5362335
    Abstract: A method is provided by which a corrosion-resistant barrier layer composed of a rare earth oxide coating incorporated in an oxide film is developed on the surface of a metal for the purpose of improving the corrosion resistance of the metal. The method is particularly suitable for forming a corrosion-resistant barrier on an aluminum alloy, in which the corrosion-resistant barrier layer is composed of a cerium oxide coating incorporated with a uniform aluminum oxide film which has been formed on the aluminum alloy. The corrosion-resistant barrier layer exhibits a broader passivation range as compared to chromium conversion coatings typically used in the art. Simultaneously, the method of this invention avoids the environmental hazards associated with chromium conversion processes, making the method more suitable for manufacturing operations. Furthermore, the method of this invention does not employ hazardous compounds, making the process suitable for a manufacturing environment.
