Title: Vladimir G Poltoratsky: Innovator in Superhard Materials
Introduction
Vladimir G Poltoratsky is a notable inventor based in Kyiv, Ukraine. He has made significant contributions to the field of materials science, particularly in the development of superhard materials. With a total of 2 patents, his work has garnered attention for its innovative approaches and practical applications.
Latest Patents
One of Poltoratsky's latest patents is focused on a polycrystalline superhard material and the method of producing it. This innovative material comprises sintered particles of cubic boron nitride, which are coated with a crystalline compound of the chemical formula B.sub.x N.sub.y C.sub.z. The unique aspect of this invention lies in the method of production, where particles of cubic boron nitride are placed in a gas flow containing carbon. This process allows for a carbon layer, ranging from 1 to 100 angstroms thick, to be built up on the surface of the particles. The particles are then subjected to sintering at specific temperatures and pressures, ensuring the material's thermodynamic stability. The resulting product is highly uniform and exhibits mechanical properties that surpass those of existing cubic boron nitride materials. For instance, under identical cutting conditions, the durability of cutters made from this new material is reported to be 2 to 5 times higher than that of traditional cubic boron nitride cutters.
