FIELD : chemistry.
SUBSTANCE : invention relates to a method of making a barrier for protection from ambient medium which is made from composite material with a ceramic matrix which contains silicon. The method of moulding a barrier for protection from the ambient environment from composite material with a ceramic matrix which contains silicon involves moulding an anticorrosion protective layer containing a compound of the type of an aluminosilicate of an alkali or alkali-earth or rare-earth element. An aluminium nitride layer which forms a chemical barrier is formed between the base and the anticorrosion protective layer.
EFFECT : high stability of protection of articles from the ambient medium.
