Abstract:
A method is provided in which a first tape is applied to an outer surface of a ceramic matrix composite (CMC). A second tape is applied to the first tape. The second tape is heated to at least a melting temperature of the second tape. During heating, the first tape is infiltrated with a molten material from the second tape, which forms a surface layer on the CMC.
