FIELD: protective coatings.
SUBSTANCE: invention is related to aircraft industry and intended to use for protection of nonmetallic materials based on silicon carbide matrix and carbon fiber filler against oxidation. High-temperature coating is composed of, wt %: silicon 4-6, boron 2-4m hafnium oxide 60-65, hafnium boride 6-10 and, additionally, hafnium silicides 7-10 and silicon boride 2-4. Resulting carbon-silicon composites are resistant to temperature 2000°C.
EFFECT: increased temperature resistance, improved environmental safety and fire and blast resistance.
