METHOD FOR OBTAINING PYROCARBON WITH THREE-DIMENSIONALLY ORIENTED STRUCTURE ON CARBON PRODUCT Russian patent published in 2014 - IPC C23C16/26

Abstract RU 2505620 C1

FIELD: metallurgy.

SUBSTANCE: pyrolysis of gaseous hydrocarbons and deposition from gas phase onto heated surface of a carbon product is performed. Natural gas is used as hydrocarbons for pyrolysis; deposition is performed at the temperature of 1200-1300°C, at natural gas absolute pressure cyclically varying in the range of 0.1 kg/cm² to 1.05 kg/cm²; bleeding-in and bleeding-out set within 0.5-5 seconds and 1-10 seconds respectively.

EFFECT: reconstruction of friction wear of carbon products owing to increasing thickness of a deposited coating.
