Abstract

Samples of the composite "diamond - titanium carbide" were obtained by high-pressure sintering of diamond powders synthesized in the Mg–Zn–C and Ni–Mn–C systems, with a titanium coating of diamond grains. The wear resistance of the obtained samples was studied by turning them into a cylindrical core of granite from the Korostyshiv deposit of the X drillability category. It was shown that applying a coating to the surface of diamond powder particles increases the wear resistance of the composite samples obtained from them in comparison with samples obtained from uncoated diamond powders
