Comparison of the corrosion resistance of zinc coatings obtained in baths with the addition of Al, Ni, Pb, Bi and Sn
Original language description
The article presents the results of research on the influence of Al, Ni, Pb, Bi and Sn additives in a zinc bath on the microstructure and corrosion resistance of zinc coatings. The microstructure at high magnifications (SEM) was revealed on the surface and cross-section of the coatings, and the chemical composition in micro-regions was determined. The corrosion resistance of the coatings was tested comparatively in neutral salt spray (PN EN ISO 9227) and in a humid atmosphere containing sulfur compounds (PN EN ISO 6988). The electrochemical corrosion parameters of the coatings were determined. It was found that the coatings obtained in the baths containing Pb, Bi and BiSn additives showed lower corrosion resistance compared to the coatings obtained in the Zn-AlNi bath. The microstructural tests showed the occurrence of Pb, Bi and BiSn alloy precipitates in the coating. These precipitates have a more electropositive potential in relation to zinc, which favors the formation of additional corrosion cells.
