【Abstract】 The influences of cerium on corrosion resistance of electroplating zinc coating are studied. The corrosion resistance of layer increases three times with cerium in the solution. The results of electron microprobe analysis and X-ray diffraction testing indicate that the layer without cerium influences the orientation effect of crystallographic plane and increases the corrosion resistance. The electroplating bath is simple and easy to maintent.更多还原
