1-11. (canceled)
A gas turbine engine component, comprising:
- a substrate;
- a thermal barrier material on the substrate;
- and
- an optically opaque oxidation resistant conforming reflective layer conforming to a porous microstructure of the ceramic coating, the conforming reflective layer comprising a platinum group metal on the thermal barrier material to enter into an interconnected porosity of the ceramic coating, the optically opaque oxidation resistant conforming reflective layer having a melting point higher than a use temperature of the ceramic coating to reduce radiation heat transport of the ceramic coating.
