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.

Process and device for coating fibers with a metal by a liquid method

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.

The invention relates to a method for metallic coating of fibers by liquid technique, in which a fiber, coated with a material forming a diffusion barrier with the metal, is drawn through a liquid metal bath to be coated therewith. The method is characterized in that prior to the passage of the fiber into the bath, the fiber is coated with a compound wettable by the metal. The coating of the fiber by the metal is facilitated by the presence of the compound, forming an interface wettable by the metal.
