FIELD: technological processes.
SUBSTANCE: invention relates to coating ceramic materials, particularly to ceramic coatings, and can be used for protection of ceramic materials used in aerospace engineering. High-temperature antioxidant coating for ceramic composite materials based on silicon carbide includes oxides of zirconium, hafnium, yttrium, silicon carbide and hafnium diboride in following ratio of components, wt%: zirconium oxide 24-33, hafnium oxide 18-24, yttrium oxide 10-18, hafnium diboride 10-20, silicon carbide - balance.
EFFECT: protection of silicon carbide-based material against oxidation at temperature of 1,750 °C for not less than 500 hours.
