FIELD: metallurgy.
SUBSTANCE: component consists of base (10) of composite material with silicon containing ceramic matrix and barrier for protection from influence of environment. The barrier is formed on the base. The barrier consists of external anti-corrosion layer (12) containing a compound of type of alkali alumo-silicate or alkali-earth or rare-earth element and of silicon containing binding sub-layer (14) formed on the base. Binding sub-layer (14) contains mullite. Its composition changes with decrease of silicon content and increase of mullite content from in essence pure silicon on its internal surface facing the base to in essence pure mullite on its external surface.
EFFECT: raised corrosion resistance of material of component at high temperatures.
