1. An infiltration apparatus comprising:
an infiltrant having a first melting point, an infiltrant source adapted to receive the infiltrant; a solid barrier having a second melting point, the solid barrier being selected from the group of materials consisting of Si/Zr, Si, SiC-coated silicon wafer, Zr/Si, ZrB2 and Ti; a component comprising a ceramic matrix composite; and a wick in fluid communication with the infiltrant source and the component, the wick being configured to draw the infiltrant from the infiltrant source into the component; wherein the second melting point is higher than the first melting point; and wherein the solid barrier is disposed between the infiltrant source and the component and coupled to the wick to block fluid communication through the wick until the infiltrant melts the barrier to allow the wick to draw the infiltrant from the infiltrant source into the component. |
