| Abstract Scope |
Cold spray additive manufacturing is a highly effective technology for repairing aerospace structures and components. Boeing, in collaboration with its partners, has been actively investigating the application of cold spray for repairing aluminum structures. Corrosion significantly impacts maintenance, repair, and overhaul operations, leading to costs that can reach hundreds of millions of dollars per year for a single program. The qualification and approval of a repair require not only adequate mechanical performance but also an assessment of the impact on the aircraft's corrosion mitigation activities.
In this presentation, we will discuss the challenges associated with the qualification process for in situ repairs of aircraft structures, with a particular focus on the effects of corrosion on high-quality repairs. We will also present the challenges encountered when using conventional techniques to evaluate galvanic corrosion between cold spray coatings and the substrate. |
