▎ 摘　　要

In this study, the corrosion behavior of Zircaloy was investigated in the presence and absence of copper-graphene nanocomposites coating. The coating was prepared employing Hummers' and electrochemical reduction methods. The morphology of copper-graphene nanocomposites coating was studied using scanning electron microscopy (SEM). Corrosion behavior was investigated employing dynamic polarization and electrochemical impedance spectroscopy (EIS) tests in a solution containing lithium hydroxide (LiOH), boric acid (H3BO3), and deionized water. The results showed that corrosion resistance of Zircaloy increased with introduction of copper-graphene nanocomposites coatings. The lowest corrosion rate was attained in the Zircaloy with copper-graphene nanocomposites coating (corrosion rate: 0.040 mm/year). An approximately 20 times decrease in the corrosion rate was observed in the Zircaloy with copper-graphene nanocomposites coating when compared to the un-coated Zircaloy (corrosion rate: 0.831 mm/year).
