Abstract

A ceramic matric composite (CMC) component (100) for a gas turbine engine, such as blade outer air seal (BOAS) (101), may be shielded from thermal stress. The CMC component (100) includes a first surface (110) configured for exposure to a hot gas stream (112), a second surface (120) configured for exposure to a cold gas stream (122), an edge surface (130) of the CMC component (100) disposed between and connecting the first (110) and second (120) surfaces. At least one coating layer (140) is disposed on the first surface (110) and wrapped over the edge surface (130) and the second surface (120), wherein the at least one coating layer (140) disposed on the second surface (120) has a lower thermal conductivity than the CMC component (100) so as to reduce a thermal gradient between the cooled first surface (110) and the heated second surface (120).
