Abstract: A method for shaping a ceramic matrix composite (CMC) sheet having a first surface and a second surface is presented. The method includes receiving an input signal representative of a predetermined shape and a type of the CMC sheet. Further, the method includes selecting a laser beam based on the received input signal. Also, the method includes projecting the selected laser beam on the CMC sheet to shape the CMC sheet into the predetermined shape.

Abstract: A system and method for performing laser induced breakdown spectroscopy during laser ablation of a coating, such as a TBC coating, deposited on a surface of a component, particularly to enable obtained spectrometry signals of the ablated coating to be used to monitor and control the laser ablation removal process in real-time. The system includes a laser energy source and a scan head interconnected with the laser energy source to receive a laser beam therefrom and then direct the laser beam onto the surface of the coated component. Collection optics collect radiation emitted from a laser-induced plasma generated by the laser beam at the surface of the coated component. The system is further equipped to spectrally analyze the radiation and generate a feedback signal for control and optimization of one or more operational parameters of the laser energy source in real-time.

Abstract: A method of fabricating and repairing a gas turbine component having a plurality of cooling holes defined therein is provided. The method includes determining a parameter of a first cooling hole defined in the gas turbine component, and generating a tool path for forming a protective cap around the first cooling hole. The tool path is based at least partially on the parameter of the first cooling hole. The method also includes directing a robotic device to follow the tool path, and discharging successive layers of ceramic slurry towards the gas turbine component as the tool path is followed such that the protective cap is formed around the first cooling hole.

Abstract: A coated component for a gas turbine engine is provided. The coated component includes a substrate having a surface and a ceramic coating. The ceramic coating includes one or more linear slots and one or more non-linear slots. The one or more non-linear slots intersect the one or more linear slots. The plurality of linear slots and the plurality of non-linear slots form segments of ceramic coating material.
