Abstract Scope |
Additive manufacturing technologies, such as cold spray, are of interest to the Naval Air Systems Command Aircraft Division (NAWCAD) and the Naval Surface Warfare Center (NSWC) as a part repair technique. To date, cold spray has been used as a repair method to restore geometrical features for proper fit and installation, but has not been approved for structural restoration. To qualify this repair technique for structural applications, the defects that cause critical failures of these materials need to be identified and an inspection technique developed to detect critical defects in repaired parts. This presentation will discuss the work completed by NAWCAD and NSWC as part of the Solid State Structural Repair Program to develop nondestructive inspection (NDI) procedures for prototype structural repairs. Results of manufacturing physical inspection standards specific for cold spray repairs, effects of defects mechanical testing, and detectability of these defects with several inspection techniques will be presented. |
