COATING SYSTEM ON A CERAMIC MATRIX COMPOSITE SUBSTRATE AND METHOD OF DEPOSITION OF A SACRIFICIAL COATING ON A CERAMIC MATRIX COMPOSITE SUBSTRATE
A coating system (20) on a CMC substrate (24) is provided, along with methods of its tape deposition onto a substrate (24). The coating system (20) can include a bond coat (26) on a surface of the CMC substrate (24); a first rare earth silicate coating (28a) on the bond coat (26); a first sacrificial coating (30a) of a first reinforced rare earth silicate matrix on the at least one rare earth silicate layer; a second rare earth silicate coating (28b) on the sacrificial coating; a second sacrificial coating (30b) of a second reinforced rare earth silicate matrix on the second rare earth silicate coating (28b); a third rare earth silicate coating (28c) on the second sacrificial coating (30b); and an outer layer (32) on the third rare earth silicate coating (28c). The first sacrificial coating (30a) and the second sacrificial coating (30b) have, independently, a thickness of about 0.1 mm (4 mils) to about 1.02 mm (40 mils).
