| Abstract: | Seven kinds of hot-dipped Zn-alloy coatings were prepared by introducing Re,Al and Mg into Al-Zn and Zn-Mg plating baths.The influence of alloying elements Re,Al and Mg on the corrosion resistance of hot-dipped galvanized coatings was investigated by conducting immersion tests,salt-spray tests and electrochemical tests(Tafel,EIS),and the anticorrosion mechanism of the coatings was primarily explored.Results show that Re,Al and Mg can all increase the corrosion resistance of hot-dipped galvanizing coatings.Z... |
