Abstract
The experimental results on the fabrication of zinc coatings during high-temperature hot-dip zinc-plating the samples made of steel 09G2S are presented. Coating microstructure and phase composition are investigated by scanning electron microscopy and energy dispersive electron probe microanalysis. It is established that the coating thickness decreases at zinc-plating temperatures of 535–565 °C and reaches the minimum at 555 °C. The ratio of phases in coating at various temperatures is analyzed. It is noted that the coating thickness is minimal when its phase composition does not contain pure ζ-phase. Recommendations for selecting the process temperature of steel with a high silicon content are given.
