“…Aluminum is the predominant component in the composition of Al alloys and Cu, Magnesium, Silicon, Manganese, Nickel, Lead, Tin, Zinc, and Cr are the primary alloying elements [7,8]. Aluminum is favored more than other metals due to its low weight, yet it is not possible to provide all of the necessary strength with aluminium alone.…”

Aluminium metal matrix nanocomposites (AMMNCs) have been recognized as a promising material with excellent structural and functional characteristics that can be suggestively personalized to satisfy industrial demands as well as design requirements for a wide range of applications, including those in defense, marine, automobiles, and aerospace. Particularly, these industries are using an increasing number of components manufactured by AMMNCs. When compared to monolithic materials, components manufactured from aluminium-based composites have better qualities such as tribological behaviors, hardness, stiffness, strength, and higher strength to weight ratio. Therefore, this article addresses the experimental investigation on aluminium-based metal matrix nanocomposites (MMNCs) with silicon carbide (SiC) and fly ash (FA) as a reinforcement material with distinct ratios. Here aluminium alloy 6061 and 7075, hereafter referred as AA6061 and AA7075, are considered as base material. The final workpieces obtained using the process of stir casting and machining are tested to compute the output response parameters like yield strength (YS), wear rate (WR), hardness, impact strength (IS), and ultimate tensile strength (UTS). In addition, the scanning electron microscopy (SEM) images also studied for examining the distribution of reinforcement material particles in base metal.

“…Further increasing the wt.% of Al 2 O 3 wear rate was considerably increased [76]. Al 7075 MMCs + 10 wt.% of Al 2 O 3 + 5 wt.% of FA signifcantly decrease the wear rate to 0.049 mm 3 /min at 10 N load [142]. Al 7075 + 1 wt.% of Mg + 4 wt.% of SiC + 4 wt.% of Al 2 O 3 with a 40 N load exhibits the least wear rate of 0.10 × 10 −3 mm 3 /min.…”

Aluminium alloy components are used in lightweight engineering applications and lack mechanical properties, wear resistance, and corrosion resistance. When hard reinforcement particulates are dispersed in the aluminium matrix alloy, aluminium matrix composites (AMCs) are formed. This new material exhibits enhanced properties such as better specific stiffness, specific strength, corrosion resistance, elastic modulus, wear resistance, and lightweight. AMCs have many favorable properties compared to their alloy and extensive applications. Especially, in the space industry, where weight reduction and an increase in modulus are prevalent, the strength-to-weight ratio is more important. This study focuses on the tribological, mechanical, and corrosion properties of Al 7075 metal matrix composites (MMCs) reinforced with one or more particulates such as aluminium oxide (Al2O3), boron carbide (B4C), titanium carbide (TiC), silicon carbide (SiC), titanium dioxide (TiO2), and titanium diboride (TiB2). In AMCs, the reinforcements are incorporated by either the solid or liquid metallurgy route. The study addresses the findings and shortcomings in the preparation of MMCs with reinforcements and their improvement in corrosion resistance, wear resistance, mechanical properties, and lower coefficient of thermal expansion than the Al 7075 base alloy. A comprehensive survey of reinforcement particulates in MMCs and their influences are outlined from the literature, encompassing recent research trends to enhance the structural properties.

“…The same effect is found at the maximum sliding speed of 3 m s −1 at lower track diameters. The coefficient of friction and wear is not just a material property or contact property, it depends on many parameters such as materials of contact pair [24], loading conditions [25], environment application [26], etc. The normal load and sliding velocity are the deciding parameters, which play an important role in controlling the wear and friction [27] in the functional application parts.…”

The present investigation is centered on examining the tribological characteristics within a pin-on-disk configuration resembling a cylinder on a flat contact surface. The pin, constructed from Stainless Steel 304 alloy, underwent sliding experiments under varying speeds (1, 2, and 3 m/s) and normal loads (10, 15, and 20 N) across track diameters of 60 and 120 mm. The experiments aimed to mitigate wear and friction in movable components, thus conducted for up to 2000 seconds in the experimental setup without any lubrication. Observations of the coefficients of friction stabilization and wear rate were made by manipulating the input parameters to anticipate the failure range. Higher coefficients of friction and increased wear rates were noted at lower sliding speeds, with wear rates stabilizing at higher speeds. Interestingly, despite a higher coefficient of friction stabilization and wear rate at a 120 mm track diameter, wear decreased. Optical Microscopy studies were carried out to examine surface damage for all normal loads and sliding speeds using both 60 mm and 120 mm track diameters. Additionally, this study employs Grey Taguchi-based Response Surface Methodology (GT-RSM) to forecast and regulate wear and friction. The findings of this study have practical implications for industries such as automotive, aerospace, and others employing SS 304 alloys in their operational components.
