Abstract

The Copper/Graphene oxide composite sheets, containing 2% graphene oxide were made by accumulative roll bonding method in four steps for the first time. The process was performed at ambient temperature and non-lubricating conditions. The initial materials were commercial pure copper and graphene oxide. In order to evaluation the produced composites the mechanical, microstructural, electrical and corrosion behavior of the produced composites were investigated at different ARB cycles. The mechanical properties of the composite were investigated by tensile, micro hardness and fractography tests before and at different stages of the process. To observe structural changes a field emission scanning electron microscopy (FESEM) equipped with an EDX spectrometer were used. The results have shown that no new phase has been produced in this composite, and only the main peak of the copper, graphene and oxygen elements could be observed in the EDX patterns. The observation of microstructure showed that in lower cycles, graphene oxide powders were more agglomerated and had non-uniform distribution and in the final stages the powders distribution was more uniformly. The fractography results revealed ductile fracture of the produced composites. The corrosion resistance and electrical conductivity of composites increased compared to pure copper.
