Abstract: Cold spray nozzle assembly for depositing powder material onto a surface of a component includes a primary spray nozzle, two or more secondary spray nozzles, and nozzle support mechanism that supports each spray nozzle. Each spray nozzle deposits powder material on a single target point on the surface, a reference-plane being defined normal to a surface-plane at the target point. The primary nozzle is in a primary-plane, the primary-plane being normal to the surface-plane, and defining a primary dihedral-angle with the reference-plane. An axis of the primary nozzle defines a primary nozzle-angle with the surface-plane. Each of the two or more secondary spray nozzles is in a corresponding secondary-plane, with each of the two or more secondary-planes being normal to the surface-plane, defining a respective secondary dihedral-angle with the reference-plane. An axis of each of the two or more secondary spray nozzles defines a respective secondary nozzle-angle with the surface-plane.

Abstract: A method comprising: cold-spraying a surface of a substrate with a bond material to form a bond coating; and cold-spraying a surface of the bond coating with a coating material to form a top coating. The bond material is different from the coating material and harder than the surface of the substrate.

Abstract: There is described an inspection device for inspecting a slot of a gas turbine engine. The inspection device comprises: an insert for insertion into the slot; a plurality of imaging devices coupled to the insert; and a processor. The insert is movable along a longitudinal axis of the slot. Each of the plurality of imaging devices is positioned adjacent an external surface of the insert and is configured to capture an image of a portion of the slot adjacent the imaging device. The processor is configured to receive data corresponding to the images captured by the plurality of imaging devices. There is also described a method of inspecting a slot using the inspection device.
