将分形几何与电化学原理相结合,编程模拟了射流电沉积中枝晶的分形生长.以平行板金属镍为阳极,石墨板为阴极,用自行设计的实验设备,通过定点喷射电沉积法制备了二维分形的镍枝晶,并采用扫描喷射电沉积法成功地改变了枝晶的分形生长,实现了枝晶的可控交织生长,进而制备了二维多孔金属材料.结果表明,扫描喷射电沉积是可以成功制备多孔金属,从而为高性能多孔金属材料的制备提供了一种全新的方法.
With the combination of fractal and electrodeposition, fractal growth process of dendrite in electrodeposition with parallel plate electrode was successfully stimulated. Using parallel plate Ni as anode and graphite plate as cathode, the fractal growing dendrite of Ni was manufactured to test the stimulation by fixed-point jet-electrodeposition. At a later time, the porous metal was manufactured by altering fractal growing of Ni in scanning jet-electrodeposition. The result proves that the porous metal can be successfully manufactured by scanning jet-electrodeposition. It would be helpful to use this method to manufacture high performance porous metal.
