Minispangling of Hot Dip Galvanized Steel 840211

The surface appearance of hot dip galvanized steels can be changed by altering the nucleation and growth of zinc spangles during solidification. This paper describes the spangle nucleation mechanisms resulting from two minispangling techniques: steam impingement and zinc dust impingement. It also characterizes the microscopic surface features of these products and their impact on painted automotive applications.
