| Abstract: | Highlights: Metallographic analysis revealed a multilayer structure composed of η, ζ, δ, and Γ phases with distinct chemical compositions. Hot dip zinc coatings produced on S235JR steel demonstrated good adhesion and structural stability. The study included metallographic, mechanical, diffraction, and tribological analyses, confirming the functional performance of the coatings. This paper presents the structural characterization of zinc coatings on S235JR steel elements. The study offers a novel and comprehensive assessment of zinc coatings applied to profiled steel elements through hot-dip galvanizing. It examines coatings formed under real industrial production conditions, providing practical insight into their behavior on complex geometries. The characterization includes metallographic, mechanical, diffraction, and tribological tests. Metallographic observations revealed the layered structure of zinc coatings, consisting of the η, ζ, δ, and Γ phases, each with varying chemical compositions and microhardness. All coatings exhibited similar resistance to damage initiation; however, microscopic analysis revealed differences in their subsequent degradation. The thickest coating showed earlier formation of adhesive cracks, indicating increased stress concentration and a faster progression of damage. [ABSTRACT FROM AUTHOR] |
