  • Patent number: 6918531
    Abstract: A metal foil connection of first and second metal foils having a thickness of less than 0.05 mm includes a connecting point in which the metal foils are brazed to one another. The connecting point forms a wedge which is filled with brazing medium. A mass of the brazing medium, and a mass of sections of the metal foils which the brazing medium contacts in the wedge, have a given ratio. A honeycomb body, a brazing medium particle fraction and a method for manufacturing metal foil connections with a thickness of less than 50 micrometers, are also provided.
    Type: Grant

  • Patent number: 6740178
    Abstract: A method for producing a metallic honeycomb configuration is described. The method includes forming a honeycomb body by stacking and/or winding layers of steel sheet containing chromium and aluminum resulting in the honeycomb body having channels through which a fluid can flow. The honeycomb body is introduced into a tubular jacket. Connections are formed between neighboring layers of steel sheet by thermal treatment. The honeycomb body is then cooled down. It is preferred for the layers of steel sheet to be provided with a rolling oil having a high carbon content before the forming of the honeycomb body, with the effect that a layer of carbon enhancing the sintering process is formed in the thermal treatment. The number of connections produced in individual regions can be further influenced by selective introduction of stresses or by stress relief.
