Effect of graphite and granite dust particulates as micro-fillers on tribological performance of Al 6061-T6 hybrid composites

Effect of bamboo char and boron carbide particles on mechanical characteristics of Aluminum 6061 hybrid composites

“…These bars are severed into the required size of crucible and melted at a temperature of 800 0 C [14]. After it reaches to molten state nitrogen gas is used for degasification from the molten liquid [15]. Mean time the moulds are prepared.…”

“…But the tensile elongation was found to decrease on increase of the micro-filler content. B 4 C being a ceramic is naturally hard and on solidification of the stircast sample, micro-sized particles get distributed along the grain boundaries of the base Al6061 alloy [15] [18]. The strengthening mechanism can be characterized from micro-mechanics of deformation comprising of higherwork hardening rates as well as modification in the grain size and dislocation density.…”

Influence of ZrB2/hBN particles on the wear behaviour of AA7075 composites fabricated through stir followed by squeeze cast technique

“…Pai et al. 15 studied the effect of graphite and granite dust particles on AA6061 alloy. The higher concentration granite particles led to higher friction during sliding owing to third body abrasive tendency.…”

Enhancing the mechanical, wear and corrosion behaviour of stir casted aluminium 6061 hybrid composites through the incorporation of boron nitride and aluminium oxide particles

“…Graphite particles plays a vital role in the hybrid Al 6061 matrix composites, as they have the self lubricating property, brittle and hard materials. Many researchers used graphite as one of the reinforcements mainly because of their good hardness and wear resistance [16][17][18][19]. Lokesh et al developed a single reinforced Al 6061 matrix composites with 2%-8% graphite reinforcement.…”
