Abstract: A method of joining first and second component bodies comprises: cold-spraying a first joining surface of the first component body with a bond material which is harder than the first joining surface; cold-spraying a second joining surface of the second component body with the bond material; and joining the first and second component bodies by way of the first joining surface.

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.
