A component of a rotary wing aircraft is provided including a surface configured to contact another component of the rotary wing aircraft such that the surface is susceptible to corrosion and/or pitting. The surface has an area from which a portion of material was removed. A structural deposit is formed by cold spraying one or more layers of powdered material within the area. The structural deposit is configured to carry a load applied to the component.

A method of repairing and inspecting a first nozzle penetrating a closed vessel. The method includes removing a portion of the first nozzle, and forming a weld between a replacement nozzle and a surface of the mid-wall of the vessel. The method further includes evaluating the integrity of the weld at the mid-wall of the vessel.

A closed vessel having a mid-wall. The mid wall is disposed between an interior wall and an exterior wall of the vessel. A first nozzle extends from a first portion of the mid-wall to the interior of the vessel. A second nozzle extends from a second portion of the mid-wall to the exterior of the vessel. A weld is disposed between the second portion of the mid-wall and the second nozzle.

A repair method is a repair method of a rotor including a rotor body extending in an axial direction about an axis and a plurality of impellers arranged in the axial direction and fixed to the rotor body, the repair method including: a step of performing welding on a repair area of the rotor body to fill a damaged portion with a welded portion; a step of performing heat treatment only on the repair area in the rotor after the welding is performed; and a step of scraping a part of the welded portion after the heat treatment is performed, to form a processing surface smoothly connected to an outer surface.
