Dispersing nanodiamond (nD) particles in metallic matrices can be achieved by ball milling resulting in metaldiamond composite powders [1] [2] [3] [4] [5][6][7]. The matrices have been selected considering the whole range of carbon affinity: copper that shows extremely reduced affinity towards carbon phases, potentially compromising the composite interfaces, and nickel and tungsten that are mild and strong carbide formers, respectively, displaying thus intermediate and strong carbon affinities.
