Abstract
A method for rapidly providing an impervious carbon substrate such as carbon fibers with a carbide coating, in atmospheric pressure, so as to provide a carbide layer bound to the carbon substrate. A carbide layer on the impervious carbon substrate is provided by coating the substrate with a concentrated solution of a carbide forming element in compound dissolved in a suitable solvent. The carbon substrate is heated to a temperature at which the carbide forming element in compound decomposes and chemically reacts with the carbon substrate to form the desired carbide layer.
