Abstract:
1. A method of coating ceramic material fibers in metal using a liquid technique, the method comprising: maintaining a charge of molten metal in levitation in a substantially spherical shape inside a crucible; causing a tensioned ceramic material fiber to travel at a predetermined speed between a bottom pulley and a top pulley disposed on either side of the crucible such that a portion of fiber is immersed in the charge to be covered in a metal coating and a volume of the charge decreases; and causing the portion of fiber that is immersed in the charge to shift during coating as a function of the remaining volume of the charge such that instantaneous height of fiber that is immersed in the charge remains substantially constant throughout the coating, wherein the portion of fiber that is immersed in the charge is shifted by a wheel which is interposed between one of the pulleys and the crucible and which shifts perpendicularly to the travel direction of the fiber.
