| Abstract: | Based on the advanced integrated technology of materials preparation and formation, a new pattern Zn-Al-Mg-RE anti-corrosion
coating for steel structure sustainable design was manufactured by cored wires and high velocity arc spraying (HVAS) technologies.
The developments of thermally sprayed coatings for steel structure protection were described. Based on Al, Zn, Zn-Al and Zn-Al-Mg
coatings, the anti-corrosion properties of new-pattern Zn-Al-Mg-RE coating were evaluated through electrochemical methods
including electrochemical polarization and electrochemical impedance spectroscopy (EIS) coupled with SEM and XRD. The models
of Zn-Al-Mg-RE coating undergoing corrosion with the initial pinhole defect and the latter with accelerated products were
also discussed. The results show that Zn-Al-Mg-RE coating exhibites excellent corrosion resistance for long-term immersion,
which is helpful for the sustainable design of steel structure in aggressive corrosion conditions. And the corrosion products
seem to possess certain self-sealing function.
