Title: The Innovations of Valentin P Varnin
Introduction
Valentin P Varnin is a notable inventor based in Moscow, Russia. He has made significant contributions to the field of materials science, particularly in the development of superhard materials. With a total of 3 patents to his name, Varnin's work has garnered attention for its innovative approaches and practical applications.
Latest Patents
One of Varnin's latest patents is for 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, resulting in a highly uniform material with superior mechanical properties. Notably, the durability of cutters made from this material is reported to be 2-5 times higher than that of traditional cubic boron nitride materials.
