Cmas-resistant abradable coatings |
| abstract |
In some examples, an article includes a ceramic or a ceramic or ceramic matrix composite (CMC) substrate; and an abradable coating on the CMC substrate. The abradable coating includes a plurality of first rare earth (RE) silicate layers in an alternating arrangement with a plurality of second RE silicate layers, wherein the first RE silicate layers include a rare earth monosilicate and the second RE silicate layers include a rare earth disilicate, and wherein the first RE silicate layers include a greater concentration of the rare earth monosilicate than the second RE silicate layers. |
