Abstract:

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 deg C.
