The behaviours of the Zinc coating would be subjected to the complex zinc anion, and also the additives, current densities and compositions of electroplating bath. In this study, the complex agents (anise aldehyde and Lugalvan P) were added into the electroplating bath to improve the anti-corrosion ability and inhibit dendritic structure on zinc coating. The Lugalvan P is added into the electroplating bath to inhibit dendritic structure during electroplating. The anise aldehyde and complex zinc ions plate a smooth zinc coating. Moreover, the crystalline structures of zinc coating analyzed by X-ray diffraction analyzer (XRD) and the surface morphology of zinc coating was observed by the scanning electron microscope (SEM). The results show that the Lugalvan P additive forms the relatively highest flatness, which inhibited the dendritic structure. High electroplating efficiency was achieved of current intensity of 3 A cm-2, and a smoothness and gloss deposited surface could be obtained. With increasing the deposition current density, it can form a better zinc coating with low plating bath resistance to form a higher anti-corrosion zinc plate.
