A dense hot-dipping Al-Zn-Si-Re-Mg coating was prepared on the surface of steel sheet. The microstructure and toughness of coating were investigated by SEM and Nano-indentation test. The polarization curve of coating was acquired in static 3.5 wt.% NaCl solution in air at 25°C. The results show that Re and Mg improve the corrosion resistance and toughness of Al-Zn-Si coating. The formation of passive film on surface of Al-Zn-Si-Re-Mg coating is easier than that of Al-Zn-Si coating. Re decreases the number of oxygen existed in the coating. Mg3Al2(SiO4)3 depresses the porosity of coating, which is a glassy compound and formed in hot-dipping process.
