The structure and composition of the diamond-matrix interface of a composite diamond-containing material obtained by combining processes of the diamond grains metallization (chromium and iron) and the tungsten-cobalt matrix sintering impregnated with copper have been studied by Raman spectroscopy. It was founded that when diamond is metallized with chromium, there are no graphite-containing formations at the diamond-matrix interface. When diamond is metallized with iron at the interface, graphite is formed as separate isolated areas 1–15 µm in size.
