FIELD: metallurgy.
SUBSTANCE: claimed process comprises the steps that follow. Carcass is made of heat-resistant fibres and partially compacted by carbon-ceramic matrix material with the help of appropriate precursors of carbon and silicon carbide and/or nitride while obtained blank is subjected to siliconising. Directly before siliconising, nano-structured carbon as particles, threads or tubes are formed on the blank material pores. Siliconising is executed by vapour-liquid-phase process with silicon introduction in material pores by capillary condensation of its vapours at temperature higher than that of siliconised blank.
EFFECT: higher serviceability under heating to high temperatures and mechanical straining in oxidising medium.
