Abstract
Iron oxide has various applications used in steel industry. In this work composites of graphene oxide and iron oxide have been prepared by horizontal dry planetary ball milling technique. Graphene oxide (1, 2 wt%) is reinforced to iron oxide to develop composites with improved hardness. Compositions of iron oxide and graphene oxide were ball milled for 14 hrs followed by sintering. X-ray diffraction (XRD) analysis shows peaks of iron oxide and graphene oxide (GO). The agglomeration of phases were found in field emission scanning electron microscopy (FESEM) study. From microstructural analysis, graphene oxide is found to be randomly distributed in the grain of iron oxide. Micro hardness value of iron oxide and GO composite was found to increase significantly when 2% of GO is added to composite. The microstructure and hardness values of the composite of iron oxide-GO (2 wt%) can be considered as the suitable potential coating material for using on surface of conventional material like mild steel to improve its mechanical behavior and wear resistant property.
