1. A multilayered coating structure, comprising:
a thermal barrier coating (TBC) layer disposed on a superalloy structure;
a metal oxide layer disposed on the TBC layer via atomic layer deposition (ALD) and comprising at least one of a rare earth metal, aluminum, zirconium, chromium, or combinations thereof, wherein the metal oxide layer has a thickness of about 1 nm to about 3 microns and has a variation in thickness of +/−50%;
a toughness enhancing layer in direct contact with the TBC layer;
a damage sensing layer in direct contact with the toughness enhancing layer, wherein the damage sensing layer comprises doped yttrium aluminum garnet (YAG) or doped yttria-stabilized zirconia (YSZ); and
an infrared (IR) reflector layer in direct contact with the damage sensing layer.
