Study of Effect of Increase of Durability of Chemical Bonding the Grains of Diamond-Like Materials, Doped Metal at Synthesis

摘要

Experience of reception of the diamond tool in many countries shows, that at addition in a diamond-like material powder of metals the durability of coupling grains in a powder' material grows. However, the internal reasons of this effect in the published literature have not found reflection. Therefore, in the given work attempt at an electronic level is undertaken to study the given problem and whenever possible to specify optimum conditions of their synthesis. With the coherent potential method of the multiple scattering theory the electron structure of the «diamond-like material - metal» system is calculated. At doped the matrix cubic boron nitride the metal observes change of the form and energy situation of top of the valence band. The analysis of electronic structures of investigated solid solutions testifies about delocalization of resonances of condition, inherent in binary connections, that can testify to easing of chemical bonding in the specified solid solutions. Results, allowing to operate by properties of a received material at the stage of development and have significant practical interest for Powder Metallurgy, are received.
