Fabrication of Titanium Metallic Composites Reinforced with Graphene Nanosheets

Abstract

Graphene-reinforced titanium matrix powders were successfully synthesized through ball milling and powder metallurgy. The prepared-samples were fabricated for the first time by vacuum arc remelting (VAR). The microstructures were observed by scanning electron microscope (SM) and X-ray diffractometer (XRD). At the same time, the defects and the number of layers of graphene added in titanium alloy were studied by Raman spectroscopy. The results show that this kind of composite material has good physical properties.
