Corrosion mitigation for gearbox

A gearbox housing of an aircraft includes a surface configured to contact with and support a load of a component of the aircraft such that the surface is susceptible to corrosion. 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 share the load applied to the surface by the component.
