Abstract
Green technology induced variety approaches to improve the environmentally citric passivation process for steel by embedding additives. This work examined the impact of inorganic ceramic graphene oxide (GO) compared to organic Urea on steel passivation as a new insight. Both of them Urea and GO inhibited the corrosion current (icorr), effectively isolated steel from a corrosive environment. Actually, the hybrid film (mix of organic citric and inorganic GO) provided a protective barrier due to the dominant role of the carboxylic groups in corrosive ions inhibition. Amino groups in Urea can form a stable complex that decays by Cl ions to yield a less protected surface. In conclusion, the development of sustainable coatings for steel is the future work to maximize its corrosion resistance.
绿色技术促使人们采用多种方法,通过嵌入添加剂来改善钢铁的环保钝化工艺。这项工作研究了无机陶瓷氧化石墨烯(GO)与有机尿素对钢铁钝化的影响。尿素和 GO 都能抑制腐蚀电流(icorr),有效地将钢铁与腐蚀环境隔离开来。实际上,混合膜(有机柠檬酸和无机 GO 的混合物)提供了一个保护屏障,这是因为羧基在抑制腐蚀离子方面起着主导作用。尿素中的氨基可以形成一种稳定的复合物,这种复合物在 Cl 离子的作用下会发生衰变,从而产生一种保护性较差的表面。总之,为了最大限度地提高钢铁的耐腐蚀性,开发可持续的钢铁涂层是未来的工作方向。
