  • Patent number: 7740960
    Abstract: A multilayered coating system consisting of a multicomponent zirconia-base or hafnia-base oxide top layer, an interlayer comprised of a plurality of sublayers and a bond coat layer is provided. The multilayered coating system of the present invention, with an interlayer comprised of a plurality of sublayers, provides a protective coating solution for silicon-base ceramic components exposed to very high temperatures and/or high gas flow velocity water vapor combustion environments. The plurality of sublayers affords for a multitude of interfaces that aid in phonon scattering within the coating system and thereby reduces its thermal conductivity. Furthermore, the plurality of interlayer sublayers afford a strain tolerant buffer between the top layer and substrate and thereby accommodate the thermal expansion mismatch between the oxide top layer (coefficient of thermal expansion (CTE) up to ˜8-10×10?6 m/m-C) and the silicon-base ceramic substrate (CTE?4-5×10?6 m/m-C).
