Abstract: A turbine component has a substrate formed from a ceramic material selected from the group consisting of a monolithic ceramic material and a composite ceramic material and a thermal barrier coating bonded to the substrate. In one embodiment, the ceramic material forming the substrate is selected from the group of silicon nitride and self-reinforced silicon nitride. In another embodiment, the ceramic material forming the substrate is selected from the group consisting of a silicon carbide-silicon carbide material and a carbon-carbon material. At least one bond coat layer may be interposed between the substrate and the thermal barrier coating.

Abstract: A thermal barrier coating comprising more than 5 to 60 mol% of at least one of La 2 O 3 and Sm 2 O 3 , and from 5 to 60 mol% of at least one oxide having a formula A 2 O 3 where A is selected from the group consisting of Sc, In, Y, Pr, Nd, Eu, Sm, Gd, Dy, Er, Yb, and mixtures thereof; and the balance zirconia. In this coating system, the zirconia is preferably present in an amount greater than 40 mol% and the coating contains less than 10 vol% of phases with a pyrochlore structure. The present invention also broadly relates to an article having a metal substrate and a thermal barrier coating as discussed above.
