| Abstract Scope |
The feasibility of the cold-spray process as an additive manufacturing technology to produce a stand-alone product has been explored. In lieu of which, thick (20mm) copper plates were fabricated using the cold-spraying technology. Heat-treatment of the plates was performed to improve their properties. The plates were characterized before and after heat-treatment using various techniques viz; scanning electron microscopy/energy dispersive spectroscopy (SEM/EDS), X-ray diffraction (XRD), microhardness, nanoindentation, porosity and density measurements, electrical and thermal conductivity measurements, and macro and micro-tensile testing. SEM/EDS showed a dense oxide-free structure with marginal porosity, which was further validated by XRD analysis. Novelty of the article includes the in-situ micro-tensile testing of the plates, which illustrates the fracture behaviour of the cold-sprayed plates. Properties of the plates achieved after heat-treatment were found comparable to that of bulk copper, which forecasts the capability of the process to be used as an additive manufacturing technology. |
