Zinc melts has been alloyed, in various proportions and combinations, with Bi, Sn, Ni, Pb. Depending on the characteristics of the alloying elements, the alloying technology of the zinc bath was established. To determine the degree of homogenization of the melt, samples were taken for metallographic analyses and chemical composition. In zinc alloyed melts were coated steel strips with low carbon. The layers obtained were analyzed in cross-section to determine the influence of the alloying elements on the Zn-Fe alloys from the support/zinc interface and on the thickness and structure of the phase ɳ (zinc). The chemical composition was determined by X-ray fluorescence and microstructure analysis by optical microscopy.
