| Popis: | The aim of this study is to investigate the effect of phosphate solution with Ca 2+ additives on weight, surface morphology and electrochemical behavior of phosphated Zn–Ni film. In order to characterize structure and morphology of surface, X-ray diffraction (XRD) and scanning electron microscopy (SEM) were applied, respectively. Results showed that the main composition in produced coatings was hopeite Zn 3 (PO 4 ) 2 ·4H 2 O, which has high corrosion resistance. On one hand, in the presence of Ca 2+ cations in solution, the weight of phosphate coating decreased, but on the other hand surface uniformity and corrosion resistance of the coating increased. |
