Title (EN) METHOD OF CERAMIC MATRIX COMPOSITE REPAIR
(FR) PROCÉDÉ DE RÉPARATION DE COMPOSITES À MATRICE CÉRAMIQUE
Abstract:
(EN) A method of treating a ceramic matrix composite article, including selecting an article having a ceramic composition formed by a process comprising an initial melt infiltration at an initial temperature with an initial infiltration material, whereby said article has at least one treatable feature. A portion of the ceramic composite is removed from a region abutting the treatable feature to form a treatment region. A treatment material including a reinforcing fiber is positioned in the treatment region and densified by a first melt infiltration with a first infiltration material including silicon. The first melt infiltration is performed at a first temperature lower than the initial infiltration temperature of the initial melt infiltration.
(FR) Cette invention concerne un procédé de traitement d'un article composite à matrice céramique, comprenant la sélection d'un article ayant une composition céramique formée par un procédé comprenant une infiltration de matière fondue initiale à une température initiale avec un matériau d'infiltration initial, ledit article ayant au moins une caractéristique traitable. Une partie du composite céramique est éliminée d'une région butant contre l'élément pouvant être traité pour former une région de traitement. Un matériau de traitement comprenant une fibre de renforcement est positionné dans la région de traitement et densifié par une première infiltration de matière en fusion avec un premier matériau d'infiltration comprenant du silicium. La première infiltration de matière en fusion est réalisée à une première température inférieure à la température d'infiltration initiale de l'infiltration de matière en fusion initiale.
