摘要	The influence of interstitial hydrogen (Hi) i ) in the oxide film of Alloy 600 was investigated using in-situ H charging via dual-exposure test and DFT calculations. H charging modified the oxide film by reducing the oxide particles in the outer oxide layer and transforming the inner oxide film from an uneven thickness and element distribution to a thicker oxide film with a homogenous element distribution. DFT calculations revealed that Hi i enhanced the Cr-O interaction while facilitating electron loss in Ni. Additionally, Hi i obviously enhanced O diffusion along the Ni-Cr surface, promoting the initial oxidation stage of the Ni-Cr surface.
