PROCEDE D'ENDUCTION D'UNE FIBRE PAR UN ALLIAGE SOUS L'EFFET D'UN COURANT ELECTRIQUE

摘要

The method comprises: providing a mass (20) of a metal alloy and heating the mass at a temperature higher than a melting temperature of the first mass so that the alloy is in a liquid state and occupies a space (E); moving a fiber (10) from an upstream to a downstream through the liquid mass in a direction in which the fiber extends such that the fiber is covered with a coating of the alloy of a non-zero thickness over an entire periphery of the fiber in a plane perpendicular to a main direction (D) on a portion of the length of the fiber; and providing an electrical current via the fiber.

The method further comprises cooling the alloy on the part of the fiber after the alloy covers all the circumference of the fiber in the transverse plane perpendicular to the main direction on the part of the fiber. An independent claim is included for a device for depositing a coating of a metal alloy on a fiber.
