Abstract
Abstract Solid fibers or capillaries are coated with a metal, alloy or dielectric capable of withstanding temperatures in excess of 300° C. and preferably 500° C. The coating is deposited by a heterogeneous nucleation thermochemical deposition process occurring on the surface of the fiber.
