  • Method for manufacturing a commutator using a brazing and soldering process
    Patent number: 9692197
    Abstract: A commutator (10) comprising a plurality of commutator bars (12) formed from a graphite structure (30) and a metal sheet (20) having soldered to the graphite structure (30) includes a brazing process followed by a soldering process. The brazing process includes applying a brazing material the graphite structure (30) and brazing at an elevated temperature to form a brazing layer (40). The soldering process includes applying a solder material to the brazing layer (40), placing the metal sheet (20) on the solder material, and soldering to form a solder layer (50) affixing the metal sheet (20) to the graphite structure (30). A plurality of grooves (70) are cut in the graphite structure (30) and the metal sheet (20) to form the commutator bars (12) arranged in an intermittent ring or circle.

  • METHOD FOR AFFIXING A METAL SHEET TO A CARBON STRUCTURE USING A BRAZING AND SOLDERING PROCESS
    Publication number: 20140287258
    Abstract: An assembly comprises a carbon structure (10), a metal sheet (40), a brazing layer (20) disposed on a surface of the carbon structure (10). The brazing layer (20) is formed by brazing a brazing material on the surface of the carbon structure (10), and a solder layer (30) disposed on a surface of the brazing layer (20) and binding the metal sheet (40) to the brazing layer (20). A method for affixing a metal sheet (40) to a carbon structure (10) and a method for metalizing a surface of a carbon structure (10) are also provided.
