Study of zinc coating fine structure and energy-dispersive elemental microanalysis of nanosized structural component of the zinc coating on steel with different contents of silicon

After the hot-dip galvanizing the multi-phase coating is formed. Its structure depends on the galvanizing regime, the composition of the molten zinc, as well as on the chemical composition of the metal, especially the silicon content. Research of the microstructure of the intermetallic layers and the secondary phase precipitates allows us to explain the role of silicon in their formation. The aim of this work is to study the fine structure and holding elemental microanalysis of nanoscale structural components of the zinc coating on steels with different contents of silicon.
