Abstract The relationship between jet flow rate,current density and cathodic overpotential was studied by measuring cathodic polarization curve in simple sulfate system.The results show that when jet flow rate increases from 0.83m/s to 5.00 m/s, overpotential increases from 1.48V to 8.52V (current density is 140 A/dm2). Compared with stir of traditional plating, cathodic overpotential increased obviously with jet flow rate increasing because of hydrogen deoxidization.Comtrol steps change from Ni2+. mH2O electrochemistry deoxidization to hydrogen deoxidization on cathodic surface with increase of current density. Overpotential can reach 12.03
