Methods for forming ceramic matrix composite articles
A method for forming a ceramic matrix composite article includes forming a ceramic matrix composite substrate comprising a ceramic fiber reinforcement material in a ceramic matrix material having a first free silicon proportion by melt infiltration; forming a ceramic matrix composite outer layer comprising a ceramic fiber reinforcement material in a ceramic matrix material having a second free silicon proportion by melt infiltration or polymer impregnation pyrolysis disposed on at least a portion of the substrate. The second free silicon proportion being less than the first free silicon proportion.
