DENSIFICATION OF MELT INFILTRATED CERAMIC MATRIX COMPOSITE (CMC) ARTICLES
Various embodiments include methods for densifying a melt infiltrated ceramic matrix composite (CMC) article, and a densified melt infiltrated CMC article formed thereby. Particular embodiments include a method including: providing a porous CMC preform within a first region of a casting apparatus; providing a molten densifier within a pressure head area of a second region of the casting apparatus, the first and second regions being operably connected and the molten densifier including at least one source of silicon; and applying a first pressure to the molten densifier within the pressure head, thereby infiltrating voids within the porous CMC preform with the molten densifier and forming a densified melt infiltrated CMC article. Alternatively, two different pressures are applied during the melt infiltration to increase the densification.
各种实施方案包括用于使熔体渗透的陶瓷基复合材料(CMC)制品致密化的方法，以及由此形成的致密化熔体渗透的CMC制品。具体实施方案包括一种方法，该方法包括：在浇铸装置的第一区域内提供多孔CMC预成型件；在浇铸装置的第二区域的压头区域内提供熔融致密剂，第一区域和第二区域可操作地连接，并且熔融致密剂包括至少一个硅源；以及向压头内的熔融致密剂施加第一压力，从而用熔融致密剂渗透多孔CMC预成型件内的空隙并形成致密化熔体渗透的CMC制品。另选地，在熔体渗透期间施加两种不同的压力以增加致密化。
