Abstract: The present application provides Calcia-Magnesia-Alumina-Silica (CMAS) (or molten silicate) resistant thermal barrier coatings (TBC). The coatings include elongate growth domains of non-equiaxed, randomly arranged overlapping grains or splats. The elongate growth domains include overlapping individual, randomly distributed splats of tough and soft phases. In some embodiments, the elongate growth domains are formed via air plasma spray. In some embodiments, the tough phases are at least partially stabilized zirconia and/or hafnia compositions, and the soft phases are CMAS (or molten silicate) reactive or resistant compositions. Within each elongate growth domain, the mixture of the tough and soft phases act together to limit penetration of CMAS and also provide sufficient domain toughness to minimize cracking forces produced during crystallization of infiltrated CMAS. The soft phases may react with the CMAS and increase its melting point, increase its viscosity, and reduce the destabilization of the tough phases.

Abstract: Systems and methods that provide or restore a coating to a component are provided. The systems and methods utilized an atomizing spray device. A slurry that comprises a fluid and ceramic particles, and a gas are supplied to the atomizing spray device. The slurry and gas are discharged from the spray device to form two-phase droplets. The fluid within the droplets evaporates to prevent the fluid from becoming part of the coating as the droplets traverse through the air and prior to impacting the surface of the component.

Abstract: Articles, such as components for high temperature turbomachinery components, include one or more coatings bearing certain perovskite compositions resistant to incursion by liquid calcium-magnesium-aluminum-silicon-oxide (CMAS) materials during service. The CMAS-reactive material includes a perovskite-structured oxide, which comprises a) a rare earth element, b) niobium, tantalum or a combination of tantalum and niobium, and c) oxygen. The CMAS-reactive material is present in an effective amount to react with a CMAS composition at an operating temperature, thereby forming a reaction product having one or both of melting temperature and viscosity greater than that of the CMAS composition.
