| Abstract Scope |
Corrosion behavior of the steel sheets with zinc-base alloyed coating was studied by total immersion test. Corrosion resistance of the zinc-base alloyed coatings dipped with different time was analyzed by means of electrochemical measurement and scanning electron microscope (SEM) analysis. The results show that the Zn-Al-Mg coating has the largest corrosion current density at the early stage of immersion. Along with increasing immersing time, corrosion current density of the Zn-Al-Mg decreases but that of the pure zinc coating and the Galfan coating increase. For the Galfan coating, diffusion characteristics could be found for the Nyquist curve, which means higher corrosion rate. However, for the Zn-Al-Mg coating, limited diffusion characteristics could be found for the Nyquist curve, which means corrosion product covered the surface enhances the corrosion resistance. |
