摘要：
The possibility of use the micro-powders of IMPACT diamond of Popigai deposit was studied for the manufacture of hybrid diamond carbide plates. The studies found that the heterogeneity of the disperse composition of the polycrystalline layer affects its physical and mechanical properties and performance. Overcoming this negative factor is possible by pre-treatment of initial diamond micro-powder providing the homogeneity of grain composition, physical and mechanical properties (strength). It allows preserving the initial grains under high pressure.
