Cladding diamond powders by thermodiffusion saturation. I. Kinetics of formation of metallic coatings on the surface of diamond

Effects of dual-layer coatings on microstructure and thermal conductivity of diamond/Cu composites prepared by vacuum hot pressing

“…The four types of layers on the diamonds demonstrate that annealing the mixture of diamonds and tungsten powder at a proper temperature for certain time can form an even and complete coating containing tungsten carbides. Manukyan et al [30] stated that the essential condition for achieving the bonding between diamond and metal is the graphitization of the diamond surface. In the XRD patterns of all samples, no graphitelike carbon phase is detected, probably due to the fact that the graphite cannot be formed or the content of graphite is too limited to be found.…”
