A vanadium-based conversion coating as chromate replacement for electrogalvanized steel substrates

▶ We develop a new environmentally friendly coating, vanadium conversion coating, for the corrosion protection of eletcrogalvanized steel. ▶ According to the results, the V-treated EG plate shows the best corrosion protection property compared with the untreated and Cr-treated EG plates. And the vanadium coating mainly consists of vanadium and oxygen, which mainly exist as V2O5, VO2, and its hydrates.
