In recent years, a great interest has been generated in the investigation of galvanized coatings, modifying them in order to improve the performance in the conditions of service. These modifications seek a significant improvement in the properties of the galvanized coating, whether in corrosion resistance, weldability or mechanical properties. The demands generated by the multiple applications of these coatings, where the coated substrate is subjected to plastic deformations (stamping, bending and laminating), requires the greater ductility of the coatings. For this reason, chemical compositions of the immersion baths have been developed, making it possible to considerably modify the microstructure of the coatings and thus their mechanical properties. This work aims to perform a bibliographic review on the chemical composition of the immersion baths, their influence on the microstructure and techniques used to determine the ductility and adhesion in galvanized coatings by hot dip.

Keywords : ductility; galvanized; Fe-Zn-Al compounds.
