PROTECTIVE COATING Russian patent published in 2006 - IPC C03C8/02 

FIELD: inorganic material coatings.

SUBSTANCE: invention relates to protective coatings, which can be used to protect structural- and technological-destination inorganic fibrous composite materials employed in parts of aviation-spatial industry and mechanical engineering. Protective coating according to invention is composed of, wt %: SiO₂ 12-15, SiB₄ 1-5, MoSi₂ 20-30, SiC 0.5-3, Si₃N₄ 0.5-3, BaO 1-5, TiC 0.5-4, Si₃C₅H₁₅O_0.25 - the balance. These coatings are suitable to protect new-generation articles.

EFFECT: increased heat resistance and adhesion to composite materials at working temperatures up to 1600°C.
