Popis: The aim of this contribution is to present a comprehensive approach to study the extent of hydrogen entry into a hot-dip-galvanized DP1000 steel, which is exposed to corrosive conditions. For this purpose, the Z100 coating was immersed in 5% sodium chloride solution at room temperature. The distribution of hydrogen and the spots of increased hydrogen entry were detected with scanning Kelvin probe (SKP) and scanning Kelvin probe force microscopy (SKPFM). Effects of hydrogen inserted during corrosion on the mechanical properties were determined in slow-strain rate tests (SSRT). Hydrogen quantification was achieved via thermal desorption mass spectrometry (TDMS), giving additional insights into the mobility of the inserted hydrogen within the steel by distinguishing diffusible and trapped hydrogen.
