Microstructure and Anti-corrosion Property of Zn-10% Al-RE Coated Steel Wire

More Information
  • Received Date: June 20, 2014
  • Zn-10% Al-RE coated steel wire was made by dual hot dipping method.The chemical compositions of alloy bath and Zn-10% Al-RE coating were analyzed by inductively coupled plasma (ICP) atomic emission spectrometry.The results showed that the content of RE in the Zn-10% Al-RE coating was far less than that in the alloy bath.The microstructures of Zn-10% Al-RE coating and Zn coating were examined and compared by SEM.The anti-corrosion property of both coatings was also analyzed by electrochemical and neural salt spraying (NSS) methods.The results showed that the corrosion current of Zn-10% Al-RE coating was about one twentieth of that of zinc coatings.The weight loss of Zn-10% Al-RE coating was one third of that of Zn coating,which proved that the anti-corrosion property of Zn-10% Al-RE coating was highly superior to that of Zn coating.
