Zinc Nickel electrodepositing process and corrosion resistance of Zinc Nickel obtained in a chloride bath with or without rare earth compounds are investigated.The experimental results show that the process of Zinc Nickel alloy belongs to "anomalous codeposition" and the nickel content (mass percent) of Zinc Nickel alloy coating is about 13%.When a small amount of rare earth compounds are added to the bath,the cathodic polarization of the electrodepositing process is increased,the alloy coatings gained from the bath become more close in structure and more fine in crystal and the corrosion resistance is also improved.
