“…The wear rates were observed in the three distinct applied loads (10N, 20N and 30N), at low load the wear rate is very low for all compositions of alloy. Wear in this region is interpreted as reflecting the fracture of the oxide layer at the wear interface, especially since the load levels involved are insufficient to cause deep penetration and deformation in the metal below the oxide [24][25][26]. At higher loads, the wear rate is more due to accelerated fracture of the oxide layer on the surface and thus cause increases the wear.…”

In the present investigation, three distinct aluminium-silicon (Al-Si) containing 7 wt.%, 12 wt.%, 14 wt.% of silicon and two different aluminium-magnesium (Al-Mg) alloys containing 2.5 wt.%, 4.5 wt.% of magnesium were prepared by casting route method. The prepared Al-Si and Al-Mg alloys have homogeneous distribution of the second rich phase throughout the cast. The microstructural analysis was done by using both optical and scanning electron microscope. Hardness values were measured with a Vickers hardness tester and tensile properties were determined by using Instron universal testing machine. Further, the wear properties were studied by using a ball-on-plate wear tester. The obtaining results highlight the hardness, tensile properties and wear resistance are increases with increasing percentage of second rich phase in aluminium. The worn surfaces of these alloys revealed that the surfaces have cracks, grooves, scoring marks and debris.

“…Yasmin et al [5] studied the mechanical and wear properties of Al-Si eutectic alloy and found that full heat treatment has a great influence on the wear and mechanical properties of the AlSi piston alloy. Haque and Sharif [6] also noted that heat treatment show a great influence on the mechanical and wear properties of the Al-Si piston alloy as it reduces the wear rate and increases the ultimate tensile strength. Modern casting processes like squeeze casting are used to cast Al-Si alloys to overcome the disadvantages of the conventional die-casting process [7].…”

Al-12Si-3Cu-1 Mg-1.78Ni alloy is widely used for piston parts in automobile industry. The present paper investigates the effect of aging time for 1-16 h at 180°C after solution treatment of the alloy at 500°C for 5 h, on alloys prepared by gravity casting and squeeze casting. The wear rate of the alloy shows a minimum at an intermediate aging time. The hardness and ultimate tensile strength showed a peak at intermediate aging time. Mechanical properties and wear resistance are found to be better in squeeze cast alloy. The result are explained based on the microstructure developed during casting process and on heat treatment for various durations.

“…Recently, near-eutectic and hypereutectic Al-Si alloys have been widely used in automotive applications, especially in the piston industry, because of their excellent combination of properties, including good abrasion and corrosion resistance, low coefficient of thermal expansion and high strength-to-weight ratio [4,5]. As the desirable combination of characteristics of Al-Si near-eutectic and hypereutectic alloys depends on the primary Si grain size to a large extent, the modification of primary Si is being studied more widely with increasing usage.…”
