METHOD FOR PRODUCTION OF COATINGS FROM CARBON NANOMATERIALS AND DEVICE FOR ITS REALISATION Russian patent published in 2010 - IPC C01B31/00 B82B3/00 C23C16/26 

FIELD: nanotechnologies.

SUBSTANCE: invention relates to nanotechnologies and may be used to produce coatings from nanodiamonds, fullerenes and carbon nanotubes, operating under extreme conditions. Mixture with negative oxygen balance, made of carbon-containing substance and oxidant, is prepared in half-closed resonant detonation chamber 2, which is part of case 1. Carbon-containing substance is produced by ethylene bubbling in bubbler 7 through kerosene heated by means of electric heater 8 in the temperature range from 500 to 750°K. Carbon-containing substance is supplied into half-closed resonant detonation chamber 2 via porous end wall 4, and oxidant - via circular slot supersonic nozzle 3, formed by internal walls 5 and porous wall 4. Then mixture detonation is periodically initiated with frequency of 100-20000 Hz with the help of detonation initiator 6 in medium inertial towards carbon. After detonation, produced flow of carbon nanoclusters from detonation chamber 2 is sent to item 15 with processed surface 16, heated by source of radiant energy 17 to temperature of 550-1300 K. At the same time with the help of drive 13 and control system 14, processed surface 16 is periodically displaced with frequency of at least 1 Hz relative to vector of carbon nanoclusters flow speed in the range of angles from -45 to 45 degrees. Speed of detonation products cooling is maintained in the range from 5·10³ to 2·10⁶ K/s.

EFFECT: invention makes it possible to produce coats from carbon nanomaterials on surfaces of bulk products of complex shape and to do fine adjustment of coats parametres.
