In this study, the influence of mechanical surface treatments on Sandelin Phenomenon in silicon containing steels was investigated. For this purpose, different surface topographies with/without deformed zones were produced on the surface of steel samples with different silicon contents by applying mechanical surface treatments such as grinding and polishing, and pickling. Hot-dip galvanized coatings formed on the conditioned surfaces were examined through cross-sections with optical microscope and scanning electron microscope. The results indicate that surface topography is the main factor controlling the stability of a hot-dip galvanizing coating. A surface topography with intermediate roughness and sharp asperities formed with abrasive particles in 100-270 μm produces suitable coatings on silicon containing steels.
