Abstract: The aim of this work is to study the electrochemical behavior of Y2O3 nanoparticles in co-deposition process with Ni2+ and Co2+, and to explore the electro-crystallization mechanism of composite coating formation. Our study involved cyclic voltammetry (CV), chronoamperometry (CA), and electrochemical impedance spectroscopy (EIS) tests for the ultrasonic-wave-assisted electrodeposition process of a plating system that contained Ni2+, Co2+ and Y2O3 nanoparticles, and obtained the kinetic parameters of co-precipitation by a calculation based on fitting the experimental curves. The results indicated that the addition of Y2O3 nanoparticles into the Ni2+-Co2+ system causes a positive shift for the initial de-position potential of Ni2+ and Co2+, and a decline in cathodic polarization. The nucleation/growth of both Ni-Co alloy and Ni-Co/Y2O3 composite coatings coincide well with Scharifker-Hill instantaneous nucleation model. Y2O3 nanoparticles can promote the nucleation of Ni2+ and Co2+ at low negative potentials, resulting in a higher nucleation rate for the Ni-Co/Y2O3 composite coating compared with the Ni-Co alloy coating, but will exert the opposite influence on the nucleation of Ni-Co alloy if more negative potentials are applied. The calculation results were in correspondence with the theoretical analysis over the experimental curves. According to the EIS result, Y2O3 nanoparticles have inconspicuous effect on the electric double layer at the electrode/electrolyte interface, but lead to diminishing charge transfer resistance in co-deposition.
