“…Hard ceramic particles which act as load bearing elements and LM13 aluminium alloy transmits the load to the reinforcements which results in higher ultimate tensile strength. Similar results have been observed in other studies that reinforcement of hard ceramic particles improved the ultimate tensile strength of composites [20,31]. Ductility of the composites was calculated using percentage of elongation and reported, Table 3.…”

LM13 aluminium alloy with boron carbide (0 wt.%–7.5 wt.%) and fly ash (2.5 wt.%) reinforced particulate hybrid composites were fabricated using liquid metallurgy route. Microstructure and mechanical properties viz., hardness, ultimate tensile strength and ductility were investigated. Wear behaviour of composites was tested by varying sliding distance and load. Fracture surface and worn surface of composites were examined using field emission scanning electron microscope. Microstructure of hybrid composites revealed uniform dispersion of particles in LM13 aluminium alloy. Hardness and tensile strength of composites increased with increasing wt.% of boron carbide and fly ash particles. Wear test results showed that addition of particles significantly decreased the weight loss and coefficient of friction. Also cumulative weight loss decreased up to 47.2 % for 10 wt.% of hybrid composites as compared to LM13 aluminium alloy. Fracture surface of composites showed dimples with particle cracking on the surface. Worn surface of LM13 aluminium alloy showed continuous grooves due to ploughing with delamination. However, worn surface of composites showed fine grooves due to the presence of hard reinforcements on the surface. Boron carbide and fly ash reinforced LM13 aluminium hybrid composites exhibited superior mechanical properties with excellent wear resistance as compared to LM13 aluminium alloy.

“…This is primarily due to their lightweight, low coefficient of thermal expansion (CTE), machinability, and improved mechanical properties, such as increased 0.2 % yield strength (YS), ultimate tensile strength (UTS), and hardness [1][2][3][4][5]. Due to these advantages, they are used in aerospace industries (airframe and aerospace components), automobile industries (engine pistons), and electronic components [6][7][8][9][10][11].…”

Ceramic particles typically do not have a sufficiently high wettability for incorporation into molten metal during aluminum matrix composite manufacturing. Metallic coatings on ceramic particles could improve their wettability by the molten aluminum and hence provide a better bonding between the reinforcement and matrix. In this study, micrometer-sized SiC particles were coated by copper, nickel, and cobalt metallic layers using electroless deposition method. These metallic layers were produced separately prior to ceramic incorporation into molten pure aluminum, in order to compare their effects on the microstructure and mechanical properties of the produced composites. The experimental results showed that copper was the most effective and nickel the least effective of these coating metals for incorporation of the SiC particles into the molten aluminum. It was additionally found that the composite, which contained the copper coated SiC particles, produced the highest microhardness and tensile strength, while that fabricated with the cobalt-coated SiC particles produced the lowest microhardness and tensile strength.

“…This penetration of silica sand abrasive particles produces larger and deeper grooves on the surface. These penetrating medium are easily producing the action of cutting and ploughing on the surface due to presence of less reinforcement particles at the surface, which results in more wear rate of the composite and the same mechanism is observed [15]. The high reinforced region (distance of 3 mm from the outer periphery) at high load (Fig.…”

Functionally graded aluminium metal matrix composite (Al-Si5Cu3/B 4 C) was fabricated through liquid metallurgy route followed by horizontal centrifugal casting method. The casting was obtained under the centrifugal die rotating speed of 1250 rpm and has the dimensions of length 150 mm, outer diameter 160 mm and thickness 20 mm. The microstructural test was performed at the surfaces those were at the distances of 3, 9 and 15 mm from the outer periphery of the casting. The tribological performance of the composite was studied using Design of Experiments. The wear experiments were conducted on the dry abrasion tester as per L 27 orthogonal array using silica sand AFS 50/70 as an abrasive medium. The parameters such as load (28, 40, 52 N), speed (100, 150, 200 rpm) and distance (3, 9, 15 mm from the outer periphery of the casting) were varied for three levels. The response studied was wear rate and the wear performance was analysed by choosing "Smaller-the-better" characteristics. The influence of parameters such as applied load, sliding speed and distance from the outer periphery of the casting on the response was studied by using Analysis of Variance and Signal-to-Noise ratio. The results revealed that distance from the outer periphery of the casting has the major impact on the wear rate followed by load and speed. The worn out surfaces were subjected to Scanning Electron Microscope analysis and the wear mechanisms were observed.
