  • Process and device for coating fibers with a metal by a liquid method
    Patent number: 8166910
    Abstract: A device used for a process of coating fibers with a metal by a liquid method is disclosed. In this process, a fiber is drawn through a bath of molten liquid metal so as to be coated with the molten liquid metal. The liquid metal bath is maintained in a crucible of the “levitation” type, which at least partly eliminates contact between the liquid metal and the crucible. The bath is fed with metal, during the process, by a metal powder.
    Type: Grant
    Filed: December 29, 2010
    Date of Patent: May 1, 2012
    Assignee: SNECMA

    Patent number: 8084099
    Abstract: A process of coating fibers with a metal by a liquid method is disclosed. In this process, a fiber is drawn through a bath of molten liquid metal so as to coated with the latter, the liquid metal bath being maintained in a crucible of the “levitation” type, which at least partly eliminates contact between the liquid metal and the crucible. The bath is fed with metal, during the process, by a metal powder. Accordingly, the molten metal bath is fed in a simple and effective manner.

  • PROCESS AND DEVICE FOR COATING FIBERS WITH A METAL BY A LIQUID METHOD
    Publication number: 20110088618
    Abstract: The invention relates to a process of coating fibers with a metal by a liquid method. In this process, a fiber (3) is drawn through a bath (15) of molten liquid metal so as to coated with the latter, the liquid metal bath (15) being maintained in a crucible (9) of the “levitation” type, which at least partly eliminates contact between the liquid metal and the crucible (9). The bath (15) is fed with metal, during the process, by a metal powder (16). Thanks to the invention, the molten metal bath is fed in a simple and effective manner.
