文摘

Single layer graphene oxide (SLGO) reinforced titanium (SLGO-Ti) nanocomposites have been achieved by laser sintering. This study focuses on the graphene oxide dispersion and survival in titanium matrix during laser sintering process. Through laser sintering, graphene oxides were dispersed uniformly into titanium matrix to fabricate SLGO-Ti nanocomposites. Microstructures and components of the nanocomposites were studied using scanning electron microscopy (SEM), X-ray diffraction (XRD), Energy-dispersive X-Ray spectroscopy (EDS) and Raman spectroscopy. It was confirmed by XRD patterns, EDS maps and Raman spectrum that graphene oxide survived in SLGO-Ti nanocomposites after laser sintering. Nanoindentation measurements showed the laser sintered SLGO-Ti nanocomposites hardness was improved by more than 3-folds than that of pure titanium counterpart.
