Tribological properties of AlSi10Mg/fly ash/graphite hybrid metal matrix composites

Abstract: Purpose – The purpose of this paper is to explore the use of fly ash and graphite particles as low cost reinforcing materials for improved wear resistance, enhanced mechanical properties and reduction in density of hybrid composites. Design/methodology/approach – The AlSi10Mg/fly ash/graphite (Al/FA/Gr) hybrid composite was synthesised by stir casting method. The dry sliding wear and friction behaviour of hybrid composites were studied using pin-on-disc machine by varying parameters like load and weight f… Show more

“…During loading, the free movement of dislocations is pinned by the reinforced ZrB 2 and TiC particles and renders significant resistance to matrix deformation caused by the indenter. Similar results were reported by earlier researchers that the hardness of matrix alloy is enhanced by the incorporation of reinforcing phases [32,33].…”

“…Hence, the temperature between the interfaces will get reduced and less chance for the formation of a thick oxidation layer which causes the comparatively high COF (Dwivedi et al , 2004). In the present case, there was a slight difference in COF for the applied load of 15 and 20 N. This is mainly because of the less chance of aluminium smearing between the sliding surfaces and the associated heat generation between the surfaces at 15 N (Venkatprasat and Subramanian, 2013).…”

“…When an applied load increases, the induced stress exceeds the fracture strength of the aluminium pin’s surface. This makes the formation of sharp edges and also dislodged the ZnO particles and trapped between the sliding surfaces may possibly induce the abrasive wear formation (Venkatprasat and Subramanian, 2013). This third body abrasion makes deep grooves on the pin’s surface which was evidently provided by scanning electron microscopy (SEM) and comparatively increases the wear rate for 20 N applied load than 15 N. The applied load, in case of a base monolithic aluminium pin, makes plastic deformation of the surface and leads to the propagation of cracks because of the fatigue related delamination wear mechanism (Suh, 1973).…”

“…A large amount of coal ash (bottom ash and fly ash) is produced from various thermal power plants across India and varies widely in their physical and chemical properties because of the variation in the quality of the coal used. Very small part of coal ash residues is used as additive in agriculture application and in enhancing properties of cement, concrete and in many composite materials (Głażewski and Eymontt, 2005; Singh and Dutta, 2013; Venkat Prasat and Subramanian, 2013; Olufemi Folagbade and David Newlands, 2014; Ben Messaoud and Mezghiche, 2016; Ridha et al , 2018; Bechar and Zerrouki, 2018; Kumar et al , 2018) and rest is disposed of to the dumping site. Presently majority of the thermal power plants in India and other parts of the world disposes coal ash at low concentration (20 per cent by weight) to ash ponds using the slurry pipeline.…”
