Abstract: A coating system configured to be applied to a thermal barrier coating of an article includes an infiltration coating configured to be applied to the thermal barrier coating. The infiltration coating infiltrates at least some pores of the thermal barrier coating. The infiltration coating decomposes within at least some pores of the thermal barrier coating to coat a portion of the at least some pores of the thermal barrier coating. The infiltration coating reduces a porosity of the thermal barrier coating. The coating system also includes a reactive phase spray formulation coat configured to be applied to the thermal barrier coating. The reactive phase spray formulation coating reacts with dust deposits on the thermal barrier coating.

Abstract: An atomizing spray nozzle device includes an atomizing zone housing that receives different phases of materials used to form a coating. The atomizing zone housing mixes the different phases of the materials into a two-phase mixture of ceramic-liquid droplets in a carrier gas. The device also includes a plenum housing fluidly coupled with the atomizing housing and extending from the atomizing housing to a delivery end. The plenum housing includes an interior plenum that receives the two-phase mixture of ceramic-liquid droplets in the carrier gas from the atomizing zone housing. The device also includes one or more delivery nozzles fluidly coupled with the plenum chamber. The delivery nozzles provide outlets from which the two-phase mixture of ceramic-liquid droplets in the carrier gas is delivered onto one or more surfaces of a target object as the coating on the target object.

Abstract: A reactive phase spray formulation coating is configured to be disposed on the thermal barrier coating of an article. The reactive phase spray formulation coating comprises a base material and a binder material. The base material has a compliance that is higher than a compliance of the binder material, the binder material has a cohesive strength that is greater than a cohesive strength of the base material, the binder material has an adhesive strength that is greater than an adhesive strength of the base material, and the binder material has a surface area of at least ten square-meters per gram that is greater than a surface area of the base material. The binder material is configured to improve a cohesive strength level, an adhesive strength level, and a compliance of the formulation coating of the thermal barrier coating relative to the formulation coating not including the binder material.

Abstract: A method for fabricating a high-density zeolite membrane structure is described. The method includes the step of combining (i) a mineral zeolite material; (ii) at least one cement precursor; and (iii) an organic binder, with an aqueous component, to form an aqueous composite zeolite composition. The zeolite composition is then applied on a surface of a scaffold formed from a porous, metal oxide material. The zeolite composition is dried, and then heated under conditions to form a metal oxide-zeolite composite layer. This layer is exposed to a phosphate composition, under conditions sufficient to reduce the porosity to a level no greater than about 10%. A high-density zeolite cement composite membrane structure results. Related methods for separating hydrogen from a fluid stream, using the membrane structure, are also disclosed.
