Paper Title:
Study on Corrosion Mechanism of Arc Sprayed Zn-Al-Mg Coatings by XRD and EIS
  Abstract

Cored wires and arc spraying were used to produce high Mg content Zn-Al-Mg alloy coatings on low carbon steel substrates. And the corrosion mechanism of the Zn-Al-Mg coatings was investigated comparing with Zn-Al alloy coatings by X-ray diffractometer (XRD) and Electrochemical impedance spectroscopy (EIS). The results show that, The Zn-Al-Mg coatings show higher electrochemical corrosion resistance in salt solution than Zn-Al coatings. With addition of Mg, the corrosion products can block off the pores in the Zn-Al-Mg coating, which is so-called self sealing, and thus prevent attack on the underlying steel substrate.
