In this study,the effect of Pb content on the surface morphology and salt spray corrosion resistance of hot dip Zn-Al-Mg coatings was investigated.The results showed that the coating surface easily formed small grains of zinc spangle structures and that the salt spray corrosion resistance of the coating decreased when Pb content was greater than 0.01%.The microstructure and energy dispersive spectrum analysis of surface and cross-sectional areas was performed by scanning electron microscopy.Pb c...
