Abstract
A method of melt infiltrating a green ceramic matrix composite (CMC) article, wherein the green CMC article includes a ceramic reinforcing structure. The method includes heating a localized region of the green CMC article; melting a metal alloy infiltrant to form a molten metal alloy; and introducing the molten metal alloy into the localized region to infiltrate the reinforcing structure of the green CMC article with the metal alloy infiltrant and form the CMC article.
