A method of coating a substrate with particles of a ceramic selected from the group consisting of diamond, carbon, graphite, and graphite or carbon-carbon composite, comprising: providing the substrate and at least one of the ceramic particles; selecting at least a carbide forming substance consisting principally of an element which is other than Ni, Cr, and Co and is capable of forming a carbide to provide a coating material; applying said coating material onto at, least one component of the substrate and the at least one ceramic particle; placing the at least one ceramic particle on the substrate; and heating the product of step (D) at a temperature sufficient to form a liquid-diffusion formed, carbide coating on the at least one ceramic particle. The ceramic particles are then coated with strong, adherent, microscopically substantially defect-free, and thermomechanically shock resistant metallized layers which are capable of practical uses over 630.degree. C.

[ I claim:] [1.] A ceramic composite structure comprising:a ceramic body and a substrate;said substrate being selected from the group consisting of a metal and a ceramic, and having a top surface including a first portion;said ceramic body including a first bottom surface overlying said first portion of the top surface of said substrate for establishing a contact area therewith;said contact area defining a first brazed bonding layer comprising a braze material between the top surface of said substrate and the first bottom surface of said ceramic body;said first brazed bonding layer including a bonding metal which forms a chemical compound of said bonding metal in said first brazed bonding layer; andsaid first brazed bonding layer being microscopically void-free so as to be substantially free of voids visible at a magnification of up to 1000.times..
