摘　　要：采用阴极极化技术和循环伏安技术,研究Fe-Ni-P合金的电化学特性.实验结果表明,Fe-Ni-P合金较Fe-Ni合金有较负的沉积电位,随着镀液pH值的增加,Fe-Ni-P合金的阴极沉积反应速度变小.采用恒电位阶跃技术研究Fe-Ni-P合金的电结晶行为,结果表明,在玻碳电极上,该合金的电结晶过程遵循瞬时成核三维生长模式,且随着过电位的增加,电极表面晶核数增多.The electrochemical properties of Fe-Ni-P alloy were measured by cathodic polarization and cyclic voltammetry. The results show that the plating potential of Fe-Ni-P alloy is more negative than that of Ni-Fe alloy. The electrocrystallization of Fe-Ni-P alloy on vitreous carbon with methods of Ⅰ-t transient curve was studied. It＇s indicated that the electro-crystallization of Fe-Ni-P alloy follows the mechanism of instantaneous nucleation and three dimensional growth, and with the increase of plating potential the number of crystal nucleus increases.
