“…A350 Al alloy showed lower coefficient value than 50% SiC reinforced material. Yalcin and Akbulut [14] found that friction coefficient value decreased with increase in volume fraction and applied load. Hassan et al [7] concluded from their study of Al-4 wt%Mg-5 wt%SiC and Al-4 wt%Mg-10 wt%SiC that the friction coefficient value is higher for both cases than the alloy metal.…”

e present paper considers the friction performance of Al-10%SiCp reinforced metal matrix composites against steel for varying tribological test parameters. e composite is prepared by stir-casting process using aluminium alloy LM6 being mixed with 10% silicon carbide by weight. e tribological tests are performed by varying applied load, sliding speed, and time. e friction performance is studied using plate-on-roller con�guration in a multitribotester and optimized using Taguchi L 27 orthogonal array. Analysis of variance (AN�VA) is performed to observe the signi�cance of test parameters and their interactions on friction performance. It is observed that normal load and the interaction between normal load and speed in�uence the friction behaviour, signi�cantly. e wear tracks are analyzed with the help of scanning electron microscopy.

“…In the past few decades, the researchers have concentrated their focus mainly on AlSiC composites fabricated using different grades of aluminium alloy as base matrix. The wear behaviour of AlSiC has been studied by varying the reinforcement volume fraction [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. Sharma et al [7] studied the wear behaviour for low volume fraction range of 0-5 %.…”

“…Sharma et al [7] studied the wear behaviour for low volume fraction range of 0-5 %. Many researchers have used volume fraction range of 5-25 % for wear study [10][11][12][13]. Ma et al [14] compared the wear behaviour using 20 and 50 % volume fraction of SiC.…”

Tribological behaviour of Al-SiC metal matrix composites prepared using two different fabrication techniques, viz. sand cast and squeeze cast techniques are studied in a multi-tribotester (TR-25, DUCOM, India) under dry sliding conditions and ambient atmosphere for varying volume fraction of reinforcement, applied load and sliding speed. Friction increases with increase in applied load and sliding speed and volume fraction of reinforcement. Wear test results show increased wear rates at higher load and speed, while increase in SiC volume fraction yields decrease in wear rate. Corrosion study conducted in 3.5 % NaCl solution shows that squeeze cast composites have better corrosion resistance than sand cast composites.Vickers's microhardness test shows improved hardness properties for squeeze cast composites compared to sand cast ones. The microstructure study of wear tracks reveals domination of abrasive wear with minor traces of adhesive wear.

“…It is now clear to the materials research community that if PMMCs are to gain industrial viability, their processing must be rendered economical and reliable and must be tailored to produce microstructures that will optimize critical properties of composites. [26][27][28][29][30][31][32][33][34] However, with conventional processing methods, the particles accumulate in stagnant zones relatively undisturbed by fluid shear in the bulk and often produce agglomerates in the ductile matrix and, as a result, the composites exhibit extremely low ductility. [35,36] Despite the continued work carried out, further efforts are required to improve the microstructure and enhance mechanical properties such as tensile strength, ductility, fracture toughness, etc.…”

Lack of efficient mixing technology to achieve a uniform distribution of fine-size reinforcement within the matrix and the high cost of producing components have hindered the widespread adaptation of particulate metal matrix composites (PMMCs) for engineering applications. A new rheo-processing method, the melt-conditioning high-pressure die-cast (MC-HPDC) process, has been developed for manufacturing near-net-shape components of high integrity. The MC-HPDC process adapts the well-established high shear dispersive mixing action of a twin-screw mechanism to the task of overcoming the cohesive force of the agglomerates under a high shear rate and high intensity of turbulence. This is followed by direct shaping of the slurry into near-net-shape components using an existing cold-chamber die-casting process. The results indicate that the MC-HPDC samples have a uniform distribution of ultrafine-sized SiC particles throughout the entire sample in the as-cast condition. Compared to those produced by conventional high-pressure die casting (HPDC), MC-HPDC samples have a much improved tensile strength and ductility.
