摘要
通过在石墨烯纳米碎片C750片层间掺杂H+,采用电泳沉积法在碳钢基体表面电泳沉积制备C750石墨烯层,运用SEM、XRD、Raman光谱等技术对C750石墨烯层的物理性能进行表征,并采用电化学方法对C750石墨烯沉积层在模拟海水环境下的防腐蚀性能及机理进行研究。结果表明:利用电泳沉积的方法可以在Q235碳钢基体上得到致密的C750石墨烯层,并且随着电解液中H^+-C750浓度的增加,此防护层的耐蚀性先提高后降低。C750石墨烯层主要通过改变阴极极化行为来起到防腐的作用。
Coatings of C750 graphene were deposited on carbon steel by electrophoretic deposition technology. They were characterized by means of scanning electron microscope（SEM）, X-ray diffraction（XRD） and Raman spectroscopy（Raman）. The corrosion performance of Q235 carbon steel with C750 graphene coating in 3.5%Na Cl solution was assessed by electrochemical methods. The result showed that C750 graphene coating could be applied on Q235 carbon steel substrate by electrophoretic deposition.With the increasing of the concentration of H~＋-C750 in the electrolyte, the corrosion resistance of C750 graphene coating increased first and then decreased. The well corrosion resistance of the C750 graphene coatings may be ascribed to that the presence of graphene changed the cathodic polarization behavior of the electrode.
