Abstract Scope |
Cold spray technique has exhibited great potential as an additive manufacturing approach for producing complex geometries and restoring damaged components. In this process, the powder feedstock is accelerated to supersonic velocities. Solid-state bonding is formed due to severe plastic deformation in the particles impacting on the underlying material. In this study, the microstructural and mechanical properties of aluminum 6061 deposits were investigated as free-standing material and repaired specimens. The properties of the deposits as free-standing material were evaluated by preparing specimens from thick deposits. Repaired specimens were also prepared by spraying the powder on notched specimens. Different thermal and thermo-mechanical post-spray treatments were applied on the deposits. The effect of different post-spray treatments on mechanical performance of the deposits were evaluated by conducting three-point bending, tensile, as well as fatigue tests. Results showed that the mechanical performance of deposits has been improved significantly by applying post-spray treatments. |
