 Abstract: The effect of Zn coating layers on hydrogen embrittlement (HE) was investigated using hot-dip galvanized (HDG) twinning-induced plasticity (TWIP) steel. The Zn coating layers consisted of an η-Zn layer and Fe-Zn intermetallic layers of ζ and δ without Γ. H was trapped particularly at the ζ layer without Zn-H compounds. The activation energies of H desorption from the δ and ζ layers were 60.0 kJ mol−1 and 75.4 kJ mol−1, respectively. The H-charged HDG_TWIP steel did not reveal HE due to the intermetallic layers, which are exceptionally brittle even when H is not enriched. © 2016 Elsevier Ltd
