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.

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.

Apparatus for providing thermal energy to an article, the apparatus comprising: a first flexible heater configured to emit infrared radiation; and a first flexible member comprising a material configured to absorb the infrared radiation emitted by the first flexible heater and to generate thermal energy from the absorbed infrared radiation, the first flexible member being configured to transfer the generated thermal energy to the article through thermal conduction.

A Cold spray nozzle assembly for depositing powder material onto a component surface includes a primary spray nozzle, two or more secondary spray nozzles, and a support mechanism supporting 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 that is normal to the surface plane, and that defines 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 secondary spray nozzles is in a corresponding secondary plane, with each being normal to the surface plane and defining a respective secondary dihedral-angle with the reference plane. An axis of each secondary spray nozzle defines a respective secondary nozzle angle with the surface plane.
