Abstract

Procédé de fabrication d’un nouveau matériau composite à matrice céramique, matériau composite en résultant et son utilisation au sein de turbomachines La présente demande concerne un procédé de fabrication d’un nouveau matériau composite à matrice céramique, le matériau composite en résultant ainsi que son utilisation au sein de turbomachines. Selon l'invention, ce procédé comprend: - la fourniture d’une préforme fibreuse poreuse formée de fibres céramiques,- la formation d’une couche d’interphase à la surface desdites fibres de la préforme fibreuse,- la mise en contact de ladite préforme poreuse avec un métal fondu choisi parmi le silicium ou un alliage de silicium pour permettre son infiltration par ledit métal fondu par capillarité,ledit procédé étant caractérisé en ce qu’il comprend en outre, avant l’étape de mise en contact de la préforme poreuse avec le métal fondu, la formation, à la surface de la couche d’interphase, d’un dépôt protecteur constitué d’un oxynitrure de silicium dont la teneur en oxygène est comprise entre 13 et 18 % en pourcentage atomique. L'invention trouve notamment application dans la fabrication de turbomachines. Figure 1
