Hot dip galvanizing is one of most important processing techniques to protect metallic materials against corrosion in many aggressive environments containing Cl-. In the last years new elements added in the bath have oriented many studies to obtain coatings characterized by different behaviors, optimized to large deformation or better external aspect. In this work an innovative zinc bath containing 0.5% wt of Titanium and 1% wt of Tin was used to generate coatings on rectangular specimens made on ipersandelin steel. Coatings, obtained for dipping times in the bath of 15, 60, 180, 360 and 900s were undergoing to bending tests. Finally metallographic analyses were performed on longitudinal section in order to evaluate intermetallic phases damage.
