  • Product and method of brazing using kinetic sprayed coatings
    Patent number: 6949300
    Abstract: The present invention is directed to a process for preparing aluminum and aluminum alloy surfaces in heat exchangers for brazing by depositing thereon a kinetic sprayed brazing composition. The process simultaneously deposits monolith or composite coatings that can include all braze materials and corrosion protection materials used in the brazing of aluminum fins to plates and tubes in a single stage.
    Type: Grant
    Filed: April 16, 2003
    Date of Patent: September 27, 2005
    Assignee: Delphi Technologies, Inc.
    Inventors: Bryan A. Gillispie, Zhibo Zhao, John Robert Smith, Thomas Hubert Van Steenkiste, Alaa A. Elmoursi, Yang Luo, Hartley F. Hutchins

  • Method for braze flux application
    Patent number: 6036083
    Abstract: The forming oil degreasing step and flux coating step are reversed as part of a basic fluxed heat exchanger brazing process. This allows the fluxed parts to be thermally degreased concurrently with the braze oven workpiece preheat process, eliminating a separate degrease step and apparatus entirely. Surprisingly, and contrary to all teaching as to electrostatic dry power coating, powdered flux was found to electrostatically bond to an oily surface as well as, or even better than, an oil free surface.
