摘要

WS2 是一种二维纳米材料，在氢气阻隔方面具有巨大的应用潜力。本文通过电沉积法在 X70 管线钢基底上制备了 WS2/Ni 复合涂层。通过电化学氢渗透试验、氢演化动力学试验、SSRT、SKPFM 和有限元分析，对复合涂层的性能进行了系统检测。结果表明，改变沉积时间会导致涂层微观结构发生变化，从而相应地影响氢渗透性能。此外，WS2/Ni 复合涂层的阻氢机理涉及两个关键过程：涂层表面对氢演化反应的抑制和涂层内部 WS2 对氢的吸附。

Manipulating nano-WS2 aggregates in electroplated Ni coating to mitigate hydrogen embrittlement in X70 pipeline steel

WS₂ is a two-dimensional nanomaterial with significant potential for hydrogen barrier applications. Herein, WS₂/Ni composite coatings were fabricated on X70 pipeline steel substrates via electrodeposition. The properties of the composite coatings were systematically examined by electrochemical hydrogen permeation tests, hydrogen evolution kinetics tests, SSRT, SKPFM, and FEM. The results indicate that varying the deposition time leads to changes in coating microstructure, which correspondingly influence hydrogen permeation performance. Furthermore, the hydrogen barrier mechanism of the WS₂/Ni composite coatings involves two key processes: the inhibition of hydrogen evolution reactions on the coating surface and hydrogen adsorption by WS₂ within the coating interior.
