Abstract
A gas turbine engine article includes a ceramic matrix composite substrate that has SiC fibers disposed in a SiC matrix, and a coating disposed on, and in contact with, the ceramic matrix composite. The coating includes, by volume percent, 5% to 20% of barium-magnesium-aluminosilicate, and a remainder of a metal-silicon-oxygen rich phase and a metal-zirconium-oxygen rich phase dispersed through the barium-magnesium-aluminosilicate.
