Abstract
A method of coating ceramic material fibers in metal using a liquid technique and a device implementing the method. The method maintains a charge of molten metal in levitation in a substantially spherical shape inside a crucible and causes 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. During coating, the portion of fiber that is immersed in the charge is shifted as a function of the remaining volume of the charge such that the instantaneous height of fiber that is immersed in the charge remains substantially constant throughout the coating operation.
