▎ 摘 要
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 alpha-Fe2O3 films. It's been observed that the work function increases under both compressive and tensile strains compared with alpha-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. (C) 2017 Elsevier Ltd. All rights reserved.
