FIELD: machine building.
SUBSTANCE: abrasive compact from superhard polycrystalline abrasive material is made at high pressure and temperature. It comprises coarser fraction of superhard material distributed among finer fraction of said material with sufficient separation so that there is no continuous passage from compact one side or surface to another via adjacent coarser grains. Compact works as high-wear-resistance fine material matrix with inclusions of coarser particles.
EFFECT: higher wear resistance and hardness.
