摘要

摘要根据文献资料，氧化石墨烯不能轻易用作金属和合金的防腐屏障，尤其是在碳钢上。本文表明，氧化形式的石墨烯可以改善碳钢的电化学腐蚀参数，如果必要的话，可以在涂层步骤之前对钢的表面结构和润湿性进行修改。本研究通过动电位极化和电化学阻抗谱研究了碳钢表面粗糙度和亲水性对电泳沉积氧化石墨烯防腐性能的影响。结果表明，增加裸钢表面的粗糙度和亲水性促进了氧化石墨烯与钢之间的机械互锁/粘附，从而提高了沉积在钢上的氧化石墨烯屏障的保护性能。

Graphene oxide as an anti-corrosion coating on carbon steel: effect of surface structure and wettability of steel

ABSTRACT According to the literature data graphene oxide cannot be easily used as an anti-corrosion barrier on metals and alloys, especially on carbon steel. This article shows that the oxidised form of graphene can improve the electrochemical corrosion parameters of carbon steel, if necessary modifications on the surface structure and wettability of steel are made prior to the coating step. In this study, the effects of surface roughness and hydrophilicity of carbon steel on the anti-corrosion performance of the electrophoretically deposited graphene oxide were investigated by potentiodynamic polarization and electrochemical impedance spectroscopy. The results showed that increasing the roughness and hydrophilicity of the bare steel surface promotes the mechanical interlocking/adhesion between the graphene oxide and steel and this improves the protective performance of the deposited graphene oxide barrier on steel.
