Abstract

Graphical abstract: Highlights: Characterisation of corrosion products and behaviour on Zn coated skinpassed steel. In situ and ex situ Raman corrosion studies of electrolytically Zn coated steel. Identification of corrosion stages in NaCl particle induced corrosion process on Zn. Difference in NaCl particle induced corrosion behaviour of smooth and skinpassed Zn. Abstract: Within this work, NaCl particle induced corrosion of electrolytically zinc coated, skin-passed steel and especially the influence of the skin-pass texture was investigated. Skin-passing is a wet-rolling procedure that applies a texture on the sample surface to improve the mechanical properties and to enhance the optical appearance of applied coatings.Samples were studied in-situ and ex-situ using Raman spectroscopy and optical microscopy in a self-designed 3D-printed weathering cell. Raman imaging and spectral correlation function were applied ex-situ to obtain more detailed information about the product distribution after drying the sample. Complementary information was obtained using SEM and EDX mapping.
