摘要：
The protective ability and corrosion resistance of conversion coatings on vanadium/galvanic zinc were assessed with chemical and electrochemical approaches. The conversion coatings were shown to possess high protective properties and corrosion resistance in a 3% NaCl solution. FT-IR and X-ray analysis data indicate that the conversion coatings on vanadium/galvanic zinc are complex systems consisting of ZnO and V2O5 oxides, as well as phosphorus-containing zinc and vanadium compounds, V(HPO4)(2), Zn-3(PO4)(2), and Zn(VO3)(2), which are resistant throughout 13-19 h in a salt-spray chamber until the appearance of the first symptoms of white zinc corrosion.
