Beschreibung
Zusammenfassung:	The invention relates to a method for depositing an environmental barrier on a part made of composite material having a ceramic matrix comprising silicon carbide fibres. The method comprises the deposition of a joining layer on at least one surface of the part, the joining layer comprising mullite or a mullite precursor, and the deposition of a protective layer on the joining layer, the protective layer comprising a rare earth disilicate.
