Abstract:
A system for infiltrating a preformed, three-dimensional, bonded-particulate component including at least one recess extending from an exterior thereof into an interior portion thereof with a liquid infiltrant, comprising:a support structure configured to substantially conformally support the preformed, three-dimensional, bonded-particulate component during infiltration thereof with the liquid infiltrant, the support structure including a refractory vessel containing an unconsolidated granulated material placed to substantially conformally surround at least a portion of the preformed, three-dimensional, bonded-particulate component and to extend into and substantially fill the at least one recess, the unconsolidated granulated material being structured so as to remain in an unconsolidated state and continue to substantially conform to adjacent surfaces of the preformed, three-dimensional, bonded-particulate component as the preformed, three-dimensional, bonded-particulate component shrinks during the infiltration thereof with the liquid infiltrant.
