Abstract: A geopolymer composite material includes a geopolymer resin, a fibrous reinforcement material embedded in the geopolymer resin for reinforcing the geopolymer resin, and a protective coating material covering the fibrous reinforcement material embedded in the geopolymer resin to provide a coated fibrous reinforcement material. Further, the geopolymer resin and the coated fibrous reinforcement material are combined together to form a prepreg containing the geopolymer resin being pre-impregnated into the coated fibrous reinforcement material and being curable into a solid matrix.

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 the 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: 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: 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: An atomizing spray device includes a housing having inlets that receive a first fluid and a slurry of ceramic particles and a second fluid. The inlets are fluidly coupled with outlets by an interior chamber that mixes the first fluid with the slurry to form a primary mixture of the first fluid and first atomized droplets of the slurry. A first outlet on a first side of the housing and a second outlet on the first side of the housing are shaped to change the primary mixture to form a secondary mixture of the first fluid and second atomized droplets of the slurry. The first outlet sprays the secondary mixture onto a first surface as a first layer of coating and the second outlet sprays the secondary mixture onto the first surface as a second layer of coating while the housing moves in a direction along the first surface.

Abstract: An atomizing spray device includes a housing having plural inlets and one or more outlets fluidly coupled with each other by an interior chamber. The inlets include a first inlet shaped to receive a first fluid and a second inlet shaped to receive a slurry of ceramic particles and a second fluid. The interior chamber in the housing is shaped to mix the first fluid received via the first inlet with the slurry received via the second inlet inside the housing to form a mixture in a location between the inlets and the one or more outlets. The interior chamber in the housing also is shaped to direct the mixture formed inside the housing as droplets outside of the housing via the one or more outlets such that, based on a discharged amount of the first fluid in the droplets, the first fluid promotes evaporation of the second fluid as the droplets traverse from the housing toward a surface of a component.

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: A method of repairing a multi-layer component of an engine in-module includes identifying a damage location on the multi-layer component. The damage location extends at least partially into a ceramic-based top layer of the multi-layer component. The method further includes depositing a material composition onto the damage location at a first temperature range so as to cover the damage location. The material composition includes one or more sintering additives. Further, the method includes applying localized curing to the material composition deposited at the damage location at a second temperature range, the second temperature range being higher than the first temperature range.
