Patent number: 11946146Abstract: 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.Type: GrantFiled: May 25, 2021Date of Patent: April 2, 2024Assignee: General Electric CompanyInventors: Hrishikesh Keshavan, Bernard Patrick Bewlay, Jose Sanchez, Margeaux Wallace, Byron Pritchard, Ambarish Kulkarni

Publication number: 20220136095Abstract: 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.Type: ApplicationFiled: January 13, 2022Publication date: May 5, 2022Inventors: Hrishikesh Keshavan, Byron Pritchard, Margeaux Wallace, Ambarish Kulkarni, Mehmet Dede, Bernard Patrick Bewlay

Patent number: 10994287Abstract: 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.Type: GrantFiled: April 30, 2018Date of Patent: May 4, 2021Assignee: General Electric CompanyInventors: Ambarish Kulkarni, Byron Pritchard, Hrishikesh Keshavan, Mehmet Dede, Bernard Patrick Bewlay

Patent number: 10875054Abstract: 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.Type: GrantFiled: February 20, 2019Date of Patent: December 29, 2020Assignee: GENERAL ELECTRIC COMPANYInventors: Ambarish Kulkarni, Byron Pritchard, Shankar Sivaramakrishnan, Krzysztof Lesnicki, Hrishikesh Keshavan, Bernard Patrick Bewlay, Mehmet Dede, Larry Rosenzweig, Jay Morgan

Patent number: 10792679Abstract: 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.Type: GrantFiled: April 17, 2018Date of Patent: October 6, 2020Assignee: GENERAL ELECTRIC COMPANYInventors: Ambarish Kulkarni, Byron Pritchard, Hrishikesh Keshavan, Mehmet Dede, Bernard Patrick Bewlay
