The goal of this paper is to investigate tribological characteristics of nano graphene platelets and hybridized nano composite, of multi- walled carbon nano tubes (MWCNT.s)/ multi-layer nano graphene platelets (MLNGPs)/lithium based grease. Characterization is done through High resolution transmission electron microscopy, X-ray diffraction. while grease properties were tested using Falex four-ball testing machine. scanning electron microscopy, and Energy dispersive X-ray diffraction were utilized to characterize the lubrication mechanism and the worn surface. Results showed that 1% of MLNGPs is the optimum concentration. WSD was reduced by 66%, friction coefficient was reduced by 91%, while maximum non seizer load increased by 90 kg over ordinary lithium grease. Hybrid MWCNTs\MLNGPs was studied the optimum ratio of MLNGPs to MWCNTs was found to be 4:1.
