“…Cobalt functions as solvent for carbon and as a catalyst for the graphite-diamond conversion, thereby favoring diamond sintering and formation of a rigid diamond framework [3,6,[90][91][92]. However, the difference in the thermal expansion coefficients of the matrix and inclusions leads to cracking of the diamond material and, as a result, rapid wear of instrument.…”

Objectives and achievements of the production of disperse composite materials (DCMs) which consist of particles with a metal coating are represented. The prospects of the DCM production by the dusty plasma method based on confining a cloud of micron-sized particles in a discharge plasma and on magnetron sputtering are shown. The method was tested in the preparation of catalyst materials, a superhard diamond polycrystalline material, and a polyquasicrystalline material with a low friction coefficient. The results of investigations of the structure and properties of powdered and sintered DCMs are presented.

“…Metallisation of diamonds grains induces a significant improvement of their performance when in the coating layer, especially at elevated processing conditions. Micro-cracks present in diamond grains are filled and the grains are encased in a metal shell, such coatings increase the strength of diamond powder, which leads to enhanced productivity of the tools [8,9].…”
