摘要

316 L在高温干燥空气、水和蒸汽中的氢加速氧化通过透射电子显微镜、原子探针断层扫描和密度泛函理论计算进行了表征。内层厚度减小的顺序为：蒸汽→水→干燥空气。间隙氢（Hi）集中在内外氧化层之间的界面处并向下扩散，形成更复杂的内氧化层。Hi通过减少空位形成和扩散能垒来促进Cr和O的扩散。

Atomic insights into hydrogen accelerated oxidation of 316 L in high-temperature water and steam

The hydrogen accelerated oxidation of 316 L in high-temperature dry air, water, and steam is characterized by transmission electron microscopy, atomic probe tomography, and density functional theory calculations. The thickness of the inner layer decreased in the following order: steam>water>dry air. Interstitial hydrogen (H_i) concentrates at the interface between the inner and outer oxide layers and diffuses downward, leading to a more complex inner-oxide layer. H_i promotes Cr and O diffusivity by reducing vacancy formation and diffusion energy barriers.
