Abstract
A method for rapidly providing a porous or impervious carbon substrate with a carbide phase, in atmospheric pressure, so as to provide maximum binding between the carbide and the carbon substrate. A carbide phase on the porous or impervious carbon substrate is provided by chemically reacting 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 compound decomposes and chemically reacts with the carbon substrate to form the desired carbide phase.
