| Abstract Scope |
Cold spray (CS) is being use in both civil aviation and military aircraft fleets as a method for repairing obsolete or damaged parts. There is also ongoing research by the United States Navy examining the corrosion and mechanical property equivalency of CS repairs on aluminum alloys for structural applications on military aircraft. Recent fatigue testing has shown that CS repair of various fatigue sample geometries with blend outs ranging from 15-30% of the sample thickness are able to improve fatigue life at multiple stress ratios and static mechanical properties to near that of an undamaged sample. This proof of concept testing has allowed CS to move towards use for aircraft structural component repair. Variations in how the spray is applied, raster pattern and dwell time, have been shown to be critical to the fatigue performance of CS repairs in aluminum alloys. |
