Abstract: A ceramic material has particular utility as a thermal insulating or thermal barrier coating on metallic substrates. The ceramic material includes gadolinia and zirconia, preferably forming gadolinia-zirconia oxide. The material may include fluorite and pyrochlore structure. This material exhibits chemical stability, thermal stability and thermal insulating properties superior to those of currently used thermal barrier ceramics, and also provides resistance to sintering and erosion comparable to currently used ceramics. A preferred material has between about 5 - 60 mol. % gadolinia.

Abstract: A turbine engine component is provided which has a substrate and a thermal barrier coating applied over the substrate. The thermal barrier coating comprises alternating layers of yttria- stabilized zirconia and a molten silicate resistant material. The molten silicate resistant outer layer may be formed from at least one oxide of a material selected from the group consisting of lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, lutetium, scandium, indium, zirconium, hafnium, and titanium or may be formed from a gadolinia-stabilized zirconia. If desired, a metallic bond coat may be present between the substrate and the thermal barrier coating system. A method for forming the thermal barrier coating system of the present invention is described.

Abstract: METHODS OF PRODUCING LAYERED CERAMIC COATINGS IN WHICH SOME LAYERS CONTAIN POROSITY ARE DESCRIBED, AS ARE THE COATINGS PRODUCED. THE DIFFERENT LAYERS ARE APPLIED AT DIFFERENT TEMPERATURE CONDITIONS BY PERIODICALLY INSERTING A HEAT BLOCKING SHIELD BETWEEN THE HEAT SOURCE AND EITHER THE EVAPORATION SOURCE AND/OR AN EXTERNAL HEATER. AS APPLIED, SOME OF THE LAYERS HAVE A ZONE I STRUCTURE AND SOME HAVE A ZONE II TYPE STRUCTURE. HEAT TREATMENT MAY BE USED TO INCREASE THE POROSITY IN THE ZONE I STRUCTURE LAYERS. FIG. 2

Abstract: A new family of ceramic materials is identified having particular utility as thermal insulating or thermal barrier coatings on metallic substrates. The ceramic materials have a pyrochlore structure and are typified by the composition A2B2O7 where A and B are various ions and 0 is oxygen. A may have a positive charge of 3 or 2 and B may have a positive charge of 4 or 5 . These materials are characterized by having chemical stability, thermal stability and thermal insulating properties superior to those of currently used thermal barrier ceramics. An example pyrochlore material is lanthanum zirconate.

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.
