Beschreibung
Zusammenfassung:	FIELD: aircraft industry. ^ SUBSTANCE: the invention is dealt with an aircraft industry and may be used for antioxygenation of non-metallic materials on the basis of silicon-carbide mold and a filler made out of carbon fibers. The technical problem of the invention is to increase oxidation resistance of carbon - ceramic composite materials at the temperature of 2000. The offered high-temperature coating contains components at the following ratio (in mass %): silicium 4-7, boron 2-4, hafnium oxide 60-65, hafnium boride 6-10, tantalum pentoxide 10-15, hafnium silicide 7-10. The invention allows to produce a high-temperature coating, that is environmentally appropriate and fire-explosive safe. ^ EFFECT: produced a high-temperature coating, that is environmentally appropriate and fire-explosive safe. ^ 2 tbl
