Abstract We report the demonstration of graphene as a passive layer that prevents hydrogen damage of steels. The effectiveness of the hydrogen damage inhibition is evaluated using graphene on α-Fe2O3 films. It's been observed that the work function increases under both compressive and tensile strains compared with α-Fe2O3 films without graphene coating, which indicates that the graphene coating strained surface layer became more corrosion resistant. The investigation of strain effect on the work function would help fundamentally understand the corrosion behavior. Our findings confirm that the graphene coating is an effective means to inhibit corrosion, even on deformed steels.

在 α-Fe 2 O 3 薄膜上使用石墨烯涂层钝化氢损伤

摘要 我们报告了石墨烯作为防止钢氢损伤的钝化层的演示。使用石墨烯在 α-Fe2O3 薄膜上评估氢损伤抑制的有效性。据观察，与没有石墨烯涂层的 α-Fe2O3 薄膜相比，压缩应变和拉伸应变下的功函数都增加，这表明石墨烯涂层应变表面层变得更耐腐蚀。研究应变对功函数的影响将有助于从根本上了解腐蚀行为。我们的研究结果证实，石墨烯涂层是抑制腐蚀的有效手段，即使在变形钢上也是如此。
