| Abstract: | Spangle constituted by some big zinc grains is a remarkable characteristic of hot dip galvanized coating known from another coating. In this paper, current research status of spangle is reviewed, including appearance of spangle, the correlation between the shape of spangle and the crystallographic orientation and the effect of alloying additions as well as the influence of the spangle on the corrosion resistance and mechanical properties of the coating. In terms of the undercooling and the crystallographic orientation and the wetting effect, the formation mechanism of the spangle is interpretated. |
