Abstract: A system for forming slots in a coating present on a component includes an electromagnetic radiation beam emitting device having a base, an arm coupled to the base, and a scan head coupled to the arm. The scan head is configured to emit an electromagnetic radiation beam, with at least one of the arm or the scan head being moveable to provide the scan head with motion about at least three axes relative to the component. The system also includes a computing system configured to control an operation of the arm to move a position of the electromagnetic radiation beam relative to a three-dimensional surface of the component such that material is ablated from a coating on the three-dimensional surface to form the slot pattern in the coating.

Abstract: A coated part, such as a ceramic coated part, having a slot formed in a coating formed on a curvilinear portion of the part and a method of forming the slot. The method includes performing a plurality of laser ablation passes. Each laser ablation pass includes focusing a laser beam to a focus depth, irradiating the coating of the curvilinear portion with the laser beam focused at the focus depth to remove coating material of the coating by laser ablation, and scanning the laser beam in a scanning direction while irradiating the coating of the curvilinear portion with the laser beam. The scanning direction is a direction transverse to a thickness direction of the coating. The focus depth of each subsequent pass of the plurality of laser ablation passes is deeper in a thickness direction of the coating than the pass preceding the subsequent pass.

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: A method includes applying an infiltration coating on a thermal barrier coating of an article. 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 method also includes applying a reactive phase spray formulation coating on the thermal barrier coating. The reactive phase spray formulation coating reacts with dust deposits on the thermal barrier coating.
