摘要

Three dimensional open-cell porous Cu was prepared by electrodeposition. The effects of experimental parameters on its morphology, structure and mechanical properties were studied. The results show that the porous Cu with apparent density within the range of 0.119-0.218 g/cm3, average pore size of 2.6 mm and the porosity within the range of 89.8%-92.6% are achieved. During the electrodeposition, a stronger cathode polarization can be obtained by reducing the CuSO4 concentration and solution temperature. Meanwhile, the porosity and apparent density of porous Cu can be controlled by the current density and deposition time. The deformation process of porous Cu can be divided into the early linear elastic stage, the next brittle failure stage and the last densification stage. The relationship between apparent density and compressive strength satisfies the power function. Moreover, the compressive strength is improved by 53% once extending the deposition time from 3 h to 5 h at 36 A/m2.
