Original Kurzfassung:
The aim of this contribution is to present a com-
prehensive 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 tem-
perature. The distribution of hydrogen and the spots of in-
creased 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 hydro-
gen within the steel by distinguishing diffusible and trapped
hydrogen
