Project summary

The object of the work is the investigation and strengthening of the properties of materials received by us and production of new high power materials for nuclear reactors, jet engines, gas turbines, energetic and laser equipment, ballistic armour, masonry of containers for storing radioactive materials, hard alloy grinding powders, drilling of diamond and carbide dies having more perfect structure with a complex of properties: increased wear resistance, hardness, strength, impact strength, resistance to corrosive media, to the action of thermal and gas-thermal impacts, high heat conductance. B4C and BN modified with borides of calcium, titanium, manganese, C-fibers, alloyed with chromium (2-10% Cr), aluminum and copper are successfully used for production of ballistic armour, protection of such armour from ballistic missile strike, using of this armour in aircraft and helicopter cabs, for production of antishock clothing (we have the stands for testing the latter).. Use of the received by us high refractory protection jackets for thermocouples of silicon carbide on nitride bond, enduring long exploitation in corrosive media under the action of gas-thermal loads enable sharp reduction of fuel-energy consumption, automatization of technological processes and increase of product quality. They were used in many countries of CIS:. Tooling of the developed by us cutting tools of corundum-carbide-nitride composite is characterized with high exploitation properties and provides high efficiency and quality treatment of materials.. The materials developed by us differ from the existing ones in that the properties characteristic for them are preserved even in high working temperatures -1800-2000oC. The industrial using of the developed production technology of the above described materials guarantees real economical effects expressed not only in the justification of monetary expenses but also high incomes, as well as guarantee of human lives in peace operations.
