Prospects of Design of Electronic Structure, Mechanical and Tribological Properties of PM Diamond-like Tool Materials

摘要

The problem of creation of cutting tool materials on a basis cubic boron nitride remains urgent at the moment. The successful search of new materials requires the understanding of the laws of formation of the chemical bonding, determining their high mechanical properties. The analysis of the tendencies of reception both formation of properties of composites and opportunities of designing of cutting tool materials with of new by properties on the basis of parameters of the electronic structure of a material is carried out. The scientific concept of designing of new materials with and by properties is developed which, includes physical principles of modeling of electronic struccture of composites of complex structure and structures, theoretical method of account of density of electronic condition of a material, technique of account of energy of chemical bonding, physical and mechanical properties, technique of computer modeling of structure of a material. By result of scientific development formation of physical bases of creation new tool, determining a new perspectiv direction in structure of metallurgy was. Practical use of the given approach has allowed to define the peculiarities of chemical bonding in composites of difficult structure and to open an electronic nature of mechanical properties in them.
