“…Nowadays, magnesium (Mg)-based alloys are of great interest in industrial sectors due to their low density which supports weight reduction in the transport industry thereby increasing fuel efficiency [5][6][7][8][9]. Carbon nanomaterial has attracted attention as a positive reinforcement for Mg [10] and its alloys over the last two decades because of its capability of improving strength in structural applications [11]. Soorya Prakash et al developed Mg-based Mg matrix composites (MMCs) using powder metallurgy (PM) route with silicon carbide-and graphitebased reinforcements.…”

In the present investigation, AZ31 alloy is homogeneously reinforced with 0.2, 0.3, 0.4 and 0.5 wt% of reduced graphene oxide (r-GO) nanosheets for the first time through a series of methodologies involving solvent processing, mechanical alloying, cold pressing and finally sintering under argon atmosphere at 560 • C. Scanning Electron Microscopy (SEM) assisted with energy-dispersive X-ray analysis revealed that this inventive fabrication route is useful to easily disperse r-GO into the matrix material and thereby attain methodical homogeneity with a uniform particle size. The attained results show that amongst the others, addition of 0.4 wt% r-GO have obviously improved the hardness up to 64.6 HV and also yielded a better inhibition efficiency of 84% on corrosion. Any further increase of r-GO content resulted for significant decrease in the wear rate up to the level of 2.6 mm 3 Nm −1 .
