In this study, we investigated a mechanism for improving paint adhesion by using Ni surface conditioning prior to dry-in-place chromate treatment, which is usually applied to hot dip Zn-coated steel sheets as a paint base.<br>The results showed that the scattered deposits of Ni on the Zn surface formed micro cells with the Zn as the anode and the Ni as the cathode.<br>Through these micro cells, insoluble chromate film (Cr(<b>III</b>)) deposited on the Ni through an electrochemical reaction of reducing the Cr(<b>VI</b>) in the dry-in place chromate solution.<br>This mechanism of generating chromate film should contribute greatly to improved paint adhesion.
