Abstract: Mechanisms of abnormal co-deposition of nickel and iron in the preparation of Ni-Fe alloy coating by electrochemical deposition are introduced. The influences of parameters of electrochemical deposition, including current density, main salt type and concentration, additives and other factors, on surface morphology, alloy composition, phase composition and performance of the Ni-Fe alloy coating are reviewed, and the applications of Ni-Fe alloy coating in wear resistance and corrosion resistance, hydrogen evolution electrode and magnetic properties are emphatically introduced. Finally, the existing problems of current Ni-Fe alloy coating are summarized, and the future development trends in this field are prospected.

Key words: Ni-Fe alloy coating, electrochemical deposition, corrosion resistance, hydrogen evolution electrode, magnetic properties
