FIELD: process engineering.
SUBSTANCE: invention relates to machine building, particularly, to production of carbon-carbon composite material coat. Proposed method comprises applying composition consisting of the mix of borosilicate glass powder and binder on material surface. Prior to applying said composition, material surface is processed by water suspension of fumarole acid in volume ratio of 1:1. Aforesaid binder is made up of composition containing (in wt %): 40-45 - ethyl silicate, 40-45 - ethanol and 10-20 - silicon organic varnish.
EFFECT: protection of composite material at 1000-1200°C for preset service life of aersospace equipment.
