Diversification of Intermetallic Zn Phases Growth on Steel During Hot-Dip Galvanizing

Open access

Abstract

The steel substrate formed as the result of oxy-acetylene cutting (OAB) was treated differently - using: softening annealing, grinding and electro-polishing. Investigations were focused on the influence of additional processing on the structure and corrosion resistance of the deposited zinc coating. The hot - dip Zn galvanizing process was conducted in industrial conditions. Parameters were fixed: temperature 457 °C, dipping time 150 s. The coating thickness diversification dependent on the sub-surface steel structure was analysed and compared to the previous results. The correlation between conducted treatment and coatings morphology was determined.
