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: A system and method described herein relate to applying an overlay metal-based coating to a metal-based substrate. An article is provided, which includes a metal-based substrate having an overlay metal-based coating disposed on the substrate at an interface. The interface is configured such that a crack formed within the overlay metal-based coating and approaching the interface has a propagation path that is more energetically favorable along the interface than through the interface and into the metal-based substrate.
