The effect of environment temperature on corrosion properties of aluminum alloy coated with graphene oxide

In this study, the effects of environment temperature on the corrosion behavior of aluminum alloy coated with graphene oxide were investigated. Graphene oxide coating process was applied by electrophoretic coating method. In order to see the effects of temperature on corrosion behavior, electrochemical corrosion tests were carried out on graphene oxide coated samples in 3.5% NaCl environment at 20 degrees C, 40 degrees C and 60 degrees C temperature. In addition, scanning electron microscope (SEM) and X-Ray Diffraction (XRD) studies were also performed. In the scanning electron microscopy studies, the graphene oxide structure, called layer-by-layer, which covers the entire surface, were observed. In EDS analysis, it was determined that the sample surfaces were generally composed of carbon and oxygen, which are graphene oxide components. In XRD analysis of graphene oxide coated surfaces, graphene oxide peaks and aluminum peaks were observed. According to the corrosion test results, it was determined that the corrosion rate increased and the corrosion resistance decreased in graphene oxide coated samples with the increase in environment temperature.
