Abstract
Microalloyed zinc melts are used in hot dip galvanized processes in order to improve products quality. Experiments aimed at obtaining zinc coatings with increased resistance to corrosion, which adhere very well to steel support, which are not conducive Fe-Zn reactions, don’t have negative environmental impacts and present uniformly dispersed phase structure in zinc matrix. To achieve these targets were chosen microalloying elements: nickel, tin, bismuth (compared to lead) and aluminium. There were made various degrees of microalloyed zinc to determine the influence of these factors on the characteristics of the melt and obtained layers. The degree of assimilation of elements in melted zinc was determined by spectrophotometer of samples alloy, taken from melt at different time intervals. There was also presented evidence of elements influence on alloy microstructure.
