| Abstract: | The electroless nickel plating was carried out with a composite additive consisting of CeCl3 and KI.The effect of the composite additive on deposit was studied by scanning electron microscopy(SEM),X-ray diffraction(XRD),potentiodynamic polarization measurement and electrochemical impedance spectroscopy(EIS).The results showed that the composite additive makes the deposit more compact and uniform,decreased the corrosion current density,and increases the charge transfer resistance.Therefore,the corrosion resi... |
