The invention provides a foamed nickel and foamed nickel-based alloy plating device, which comprises a plating tank, a solution storage tank, a plating solution circulation pump and a power system, wherein a foam matrix electrode is fixed in the middle of the plating tank; two anode electrodes are respectively fixed on the edges of the plating tank; plating solution is circulated between the plating tank and the solution storage tank by the plating solution circulation pump to complete plating in the plating tank; and the plating solution in the plating tank contains 50-120g/L of nickel sulfate. Compared with the traditional plating device, the foamed nickel and foamed nickel-based alloy plating device has the advantages that the polarization caused by the diffusion effect can be reduced; the uneven influence of local diffusion is eliminated; bubbles can be discharged in time, so that a plating layer is even; a process apparatus is simple; and the operation is convenient.
