Abstract

Mg thin films were prepared by PVD method on electroplated Zn steel substrate. And the influence of gas pressure on their morphology and crystal orientation of the deposited films were investigated by scannig electron microscopy(SEM) and X-ray diffraction(XRD), respectively. In addition, the effect of corrosion resistance of these films as a funtion of morphology and crystal orientation was evaluated by anodic polarization test. From the measured results, it is investigated that the film of granular structure which deposited in condition of high gas pressure had the highest corrosion resistance.
