| Abstract: | A titanium salt conversion coating used for continuous hot-dip galvanized steel sheet was studied.The optimal conditions of titanium salt passivation were obtained by orthogonal test and single factor test as follows:Ti(SO4)2 8 g/L,H2O2 80 mL/L,HNO3 6 mL/L,H3PO4 6 mL/L,passivation temperature 30 °C,and passivation time 10 s.The results of SEM and energy-dispersive spectroscopy indicated that the conversion film obtained from the optimal process is uniform and compact,and consists of O,P,Ti,and Zn.Electrochemical test showed that the titanium salt passivation film presents an obvious passivation area,has an increased polarization resistance of 15-17 k?,and can endure more than 24 h in neutral salt spray corrosion test. |
