Abstract
In this study, the influence of mechanical surface treatments on the Sandelin Phenomenon in silicon containing steels was investigated. For this purpose, various surface topographies with/without deformed zones were produced on the steel samples with different silicon contents by applying mechanical surface treatments such as grinding, and polishing in addition to conventional 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 and a surface topography with intermediate roughness and sharp asperities formed with abrasive particles in the range of 100 - 270 μm can produce suitable coatings on the silicon containing steels
