    Abstract:

    Porous Cu/Ni composites with uniform pore distribution were prepared by electrodeposion method and its coating layer number is from 2 to 5. The effects of processing parameters on both microstructure and mechanical properties were studied. The microstructure morphology and characteristic parameters of porous Cu/Ni composites were strongly dependent on coating layer number. As the coating layer number increased, the pore diameter and porosity decreased while the specific surface area and apparent density increased. The solid solution formed at the Cu and Ni layer interface due to the atomic diffusion. The mechanical properties of the composites were remarkably enhanced with the increase of coating layer number. The compressive strength reached 17.36 MPa and Young"s modulus increased by 7.9 times. Moreover, the energy absorption of per unit volume rose up by 13.9 times as the coating layer number increased to 5.
