A coated fiber is provided. The coated fiber comprises a ceramic or carbon fiber having a coating thereon of a refractory metal or metal-based ceramic material, the coating being substantially uniform and having a morphology which is fully dense and substantially void free. Further provided is a process for coating ceramic or carbon fibers in continuous tows or bundles comprising (a) applying sufficient current to a metal cathode to form a plasma of atoms and ions of the cathode material, (b) positioning said fibers in the path of said plasma, said plasma causing said fibers to billow, and (c) causing said plasma to condense on said fibers to form a refractory metal or a metal-based ceramic coating. |
