Abstract Graphene oxide (GO) is used to accelerate zinc phosphating process on steel. The effect of GO on microstructure and corrosion resistance of phosphate coating is investigated. Experiments show that GO sheets can act as sedimentary beds at the initial stage of phosphating process, which can capture metal ions and thus favor the nucleation of phosphate crystals. When the concentration of GO is optimized to be 1.2 g/L, the phosphate coating possesses the most uniform and compact structure and achieves the strongest corrosion resistance. Results demonstrate that GO can effectively accelerate phosphating process and enhance corrosion resistance of phosphate coating.

氧化石墨烯加速钢上快速低温磷酸锌涂层

摘要 氧化石墨烯（GO）用于加速钢的锌磷化过程。研究了氧化石墨烯对磷化层微观结构和耐腐蚀性能的影响。实验表明，GO 片在磷化过程的初始阶段可以作为沉积床，它可以捕获金属离子，从而有利于磷酸盐晶体的成核。当GO浓度优化为1.2 g/L时，磷化层结构最均匀致密，耐腐蚀性能最强。结果表明，GO可有效加速磷化过程，提高磷化层的耐腐蚀性能。
