摘要：

The results of hot-dip galvanizing of low-silicon steel (08X grade) and reactive steel (S235JRG2 grade) samples in zinc bath made of tin-free WEGAL alloy with manganese content increased to 0.2% (ZnAl0.1Ni0.1Mn0.2) have been presented. The researched WEGAL alloy microstructure and phase composition were shown. Its melting point was determined basing on thermal analysis of solidification. Galvanizing tests were performed at the temperature of 445 degrees C, with retention time - 10 min. Analysis of tests results comprised assessment of coatings microstructure and thickness. The manual bending tests of galvanized samples on steel mandrel (angle 180 degrees, radius 5 mm) were carried out with visual evaluation of samples outside edges. Obtained coatings were characterized by good plasticity and aesthetical appearance. The importance of zinc bath composition on coating growth kinetics has been demonstrated.
