Abstract: A coating system includes a support fixture sized to be partially inserted into one or more openings of a component and a spray nozzle segment device comprising a housing configured to receive a slurry. The device is disposed radially outward of a central axis of the component and is shaped to extend circumferentially about at least part of the central axis of the component. The housing comprises plural delivery nozzles configured to spray the slurry onto a surface of the component. The device is operably coupled with the support fixture such that the fixture maintains a position of the device within the component when the support fixture is partially inserted into one or more openings of the 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 gas and a slurry that comprises fluid and ceramic particles 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: Methods for preparing slotted ceramic coatings and the resulting components comprising the same are provided. The methods and products include the incorporation of a coating system comprising a ceramic coating with cooling holes disposed throughout the ceramic coating and slots defined in the thermal barrier coating and disposed in relation to the cooling holes. The resulting ceramic coating has improved resistance to CMAS infiltration and improved compliance resulting in an increased life of the coated component.

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
