Removing coatings from ceramic matrix composite substrates
A method for removing a coating including a rare earth silicate from a substrate including a ceramic or ceramic matrix composite may include contacting a coating comprising a rare earth silicate with a liquid comprising an active species. The active species may include at least one of a mineral acid or a base. The method also may include working the coating to cause removal of at least a portion of the coating.
