Abstract
Physico-mechanical characteristics of micron powders of synthetic (SD 40/28) and natural (ND 40/28) diamonds and of polycrystalline composite materials based on them have been studied. Both the powders have been shown to meet the requirements of DSTU 3292-95 (State Standard of Ukraine). At the same time the abrasiveness of natural diamond is higher than that of synthetic diamond, while the grain density and specific surface is lower than that of synthetic diamond grains. The elastic characteristics of sintered polycrystalline composite materials (the Young modulus, shear modulus, bulk modulus, Poisson ratio, and wear resistance in stone working by friction) of a composite sintered from the natural diamond micron powder are higher, while the life at cyclic compression is somewhat lower as compared to a composite sintered from the synthetic diamond micron powder.
