According to the i - t curves of potential step , it was revealed that electrocrystallization of ni - w - b alloy on glassy carbon followed the mechanism of instantaneous nucleation and three dimensional growth with diffusion controlled . the crystal nucleus number on the surface of electrode raised by the increase of over potential 根据电位阶跃的i t曲线分析得知，在玻摘要碳电极上ni wb合金电结晶过程遵从扩散控制瞬时成核三维成长模式进行，且随着过电位的增加，电极表面上晶核数增多。
