Abstract

L'invention concerne la fabrication d'une pièce (10') en CMC, via une imprégnation en fusion (MI), par l'intermédiaire d'une coulée en suspension que l'on réalise dans un creuset (31) contenant un alliage de silicium (33) en fusion et dans lequel est disposée la pièce. Le creuset, qui est en graphite naturel épuré, présente un fond (37) d'où s'élèvent des parois latérales (39), suivant une pente (A) comprise entre 25 et 35°. L'imprégnation en fusion est réalisée par l'intermédiaire de l'un parmi : un drain (35) d'apport de l'alliage en fusion à la pièce, de sorte que l'alliage infiltre par capillarité le drain puis la pièce (10') à traiter, et une quantité d'alliage fondu dans le creuset telle que, dans le creuset, la pièce à traiter trempe directement dans l'alliage fondu, liquide.The invention relates to the manufacture of a part (10 ') in CMC, via molten impregnation (MI), by means of a suspension casting which is carried out in a crucible (31) containing an alloy. of molten silicon (33) and in which the part is placed. The crucible, which is made of pure natural graphite, has a bottom (37) from which side walls (39) rise, along a slope (A) of between 25 and 35 °. The molten impregnation is carried out by means of one of: a drain (35) for supplying the molten alloy to the part, so that the alloy infiltrates the drain by capillary action and then the part ( 10 ') to be treated, and a quantity of molten alloy in the crucible such that, in the crucible, the part to be treated is dipped directly into the molten, liquid alloy.
