Abstract
In this work, Cu-0.5Cr-0.05Zr (wt.%) samples obtained by the cold spray process were studied regarding the microstructure and the mechanical properties versus several heat treatments. Ultimate tensile strength higher than 600 MPa, yield strength of 570 MPa and Vickers hardness HV0.2 of about 200 were obtained. Comparison of these results with those obtained by forging or vacuum plasma spraying highlighted the ability of the cold spray technique to produce dense Cu-Cr-Zr deposits with low oxygen content, low level of residual stresses and high mechanical properties.
