Abstract: Embodiments of the present disclosure are directed to an article and methods of forming the article. The article includes a thermal barrier coating disposed on a substrate. The thermal barrier coating includes a thermal barrier material and partially filled surface-connected columnar voids. The partially filled surface-connected columnar voids are interspersed with the thermal barrier material in the thermal barrier coating. At least some of the partially filled surface-connected columnar voids include a calcium-magnesium-aluminum-silicon-oxide (CMAS)-reactive material disposed within, such that the CMAS-reactive material is physically separated from the substrate by a columnar cavity having an aspect ratio greater than 3.

Abstract: An article for service at high temperatures comprises a substrate comprising a first region and a second region; and a coating disposed over the substrate. The coating comprises a first portion disposed over the first region of the substrate and a second portion disposed over the second region of the substrate. The coating includes a layer comprising a ceramic material and further including a quantity of surface-connected voids, and a protective agent is disposed within at least some of the surface-connected voids of the layer. Within the first portion, the agent is present within the layer at a concentration of less than or equal to 4 percent by volume of the layer exclusive of the voids, while, within the second portion, the agent is present within the layer at a concentration up to the carrying capacity of the layer. Methods for forming the article are also presented.

Abstract: A coating analysis system and method inductively heat a component having a coating. Optionally, the component is heated while a cooling fluid flows through cooling holes extending through the component and the coating. The system and method measure rates of infrared radiation emission from the component and the coating at different locations on the component and the coating. The system and method determining bond qualities (e.g., tensile strengths of bonds) between the coating and the component at the different locations based on the rates of infrared radiation emission that are measured.

Abstract: The subject matter disclosed herein relates generally to light-curable ceramic slurries, and more specifically, to hybrid binders for light-curable ceramic slurries. A light-curable ceramic slurry includes a hybrid binder having an organic resin component and a multi-functional reactive siloxane component that is miscible with the organic resin component. The slurry also includes a photoinitiator having a corresponding photoactivation wavelength range and ceramic particles. The slurry is cured via exposure to light in the photoactivation wavelength range of the photoinitiator such that both the organic resin component and the multi-functional reactive siloxane component of the hybrid binder polymerize.

Abstract: Ceramic slurries may include ceramic particles, a photoreactive-photostable hybrid binder, and a photoinitiator. The photoreactive-photostable hybrid binder may include a photoreactive organic resin component, a photoreactive siloxane component, and one or more photostable siloxane components. Methods of forming a ceramic part may include curing a portion of a ceramic slurry by exposing the portion of the ceramic slurry to light to form a green ceramic part, and partially firing the green ceramic part to form a brown ceramic part. The brown ceramic part may be sintered at or above a sintering temperature of the ceramic particles to form a ceramic part, wherein sintering includes heating the brown ceramic part to a sufficient temperature to promote reaction bonding that converts silica from the photoreactive-photostable hybrid binder into silicates that bond with the ceramic particles.
