Abstract: A coated article, a process of coating an article, and a process of using an article are disclosed. The coated article includes a substrate, a porous coating material, and a thermal barrier coating material. The porous coating material includes a porosity between about 1 percent and about 20 percent, by volume. The thermal barrier coating material has a thermal conductivity that is lower than a thermal conductivity of the substrate. The porous coating material differs in one or both of composition and microstructure from the thermal barrier coating material. Additionally or alternatively, the porous coating material resists at least one of sintering, densification, and phase destabilization for a predetermined period at a predetermined temperature. The process of coating an article includes applying a coating to form the coated article.

Abstract: A coating method is disclosed including forming a first layer on a substrate and forming a second layer on the first layer. Forming the first layer includes applying virgin powder particles containing at least one rare-earth doped ceramic oxide onto the substrate. Forming the second layer includes applying recycled powder particles containing the at least one rare-earth doped ceramic oxide and at least one extraneous material onto the first layer. Another coating method is disclosed including mixing the virgin powder particles with the recycled powder particles to form a mixture of powder particles, and applying the mixture of powder particles onto the substrate. A coated article is disclosed including a substrate and a coating on the substrate, the coating including virgin powder particles of at least one rare-earth doped ceramic oxide and recycled powder particles including the at least one rare-earth doped ceramic oxide and at least one extraneous material.

Abstract: A treatment process, an oxide-forming treatment composition, and a treated component are disclosed. The treatment process includes applying an oxide-forming treatment composition to a ceramic coating and heating the oxide-forming treatment composition to form an oxide within the ceramic coating. The oxide-forming treatment composition includes a solute and a corrosion inhibitor. The oxide-forming treatment composition is super-saturated with the corrosion inhibitor. The treated component includes a ceramic coating and one or both of a corrosion inhibitor and an oxide formed by an oxide-forming treatment composition having the corrosion inhibitor. The corrosion inhibitor and the oxide-forming treatment composition are within the ceramic coating.
