“…Lots of works were completed by researchers to improve the wear resistance of aluminium alloys [6,7]. Recently, many secondary phases have been added into aluminium alloys to fabricate aluminium matrix composites with high wear resistance [8][9][10][11]. Altınkök [12] reported that fine Al 2 O 3 /SiC particles were propitious to the effects on the tribological properties of Al-based composite.…”

Abstract:The effects of 0, 0.3, 0.6 and 0.9 wt % modifier La on the dry sliding wear behaviours of AlSi5Cu1Mg alloy were investigated under different friction conditions (normal loads, sliding velocities) by using pin-on-disc configuration. The microhardness of the alloys was tested, and it was found that the microhardness of the alloys was improved by the La addition. The AlSi5Cu1Mg + 0.6 wt % La alloy exhibited the smallest grain size and maximum microhardness. The wear mechanism analysis of the worn surface was done, which drew support from a scanning electron microscope (SEM) that was equipped with an energy dispersive spectrometer. The results showed that AlSi5Cu1Mg + 0.6 wt % La alloy exhibited the best wear resistance, which was mainly due to the modified grain and microhardness. At the sliding velocity of 0.19 m/s, the adhesive wear became the main wear mechanism with the increase of the load because of the rupture of the oxide layer on the friction surface. Under the load of 3.8 MPa, the abrasive wear became slight as the sliding velocity increasing, due to the recrystallization phenomenon that happened in the frictional surface.

“…The ceramic nanoreinforcement particles have a special attention to their outstanding properties such as high strength per density, high melting point, better wear resistance and good corrosion resistance [12]. The properties of aluminium metal matrix composites improve by reinforcing ceramic particles such as SiCp [13], Al2O3 [14], B4C [15], TiB2 [16], AlN [17], and TiC [18]. Among all the ceramic reinforcements, the SiCp ceramic particles reinforced aluminium based composites attain good mechanical properties and wear resistance.…”

The present study focused on the wear performance of AA6061/ SiCp (1, 1.5 and 2 wt. %) of nanocomposites at dry sliding condition. The nanocomposite specimens were fabricated through ultrasonic assisted stir casting technique. The wear experiments were conducted under normal atmospheric conditions using a pin-on-disc apparatus. Three different applied normal loads on nanocomposite pin (10 N, 15 N, and 20 N); at various sliding velocities of (1 m/s, 1.5 m/s, and 2 m/s); and at sliding distances of (1000 m, 2000 m, and 3000 m) were considered. The influences of applied normal load on nanocomposite pin, wt. % of SiCp reinforcement particles, sliding velocity, and sliding distance on both friction coefficient and wear loss were studied. The changes of wear loss and friction coefficient with varying applied normal loads, sliding velocities, and sliding distances were plotted. It was observed that the wear loss increased linearly with increasing sliding distance and sliding velocity. This was due to the increase of oxidation layer on the pin surface. The average friction coefficient at sliding velocity 1 m/s for 1 wt. % of SiCp, 1.5 wt. % of SiCp, and 2 wt. % of SiCp reinforced nanocomposites at sliding distance 3000 m, at 20 N normal loads was 0.29, 0.43, and 0.46, respectively. The average friction coefficient at 2 m/s sliding velocity for the same load and sliding distance was 0.26, 0.27, and 0.28, respectively. The increase of SiCp reinforcement in the matrix increased the friction coefficient due to its cubic crystal structure. The increase of sliding velocity and sliding distances reduced the friction coefficient. The worn surfaces of the samples were examined using SEM and EDX analyses. SEM micrograph analysis of the wear surfaces of the nanocomposites exhibited the abrasion wear and oxidative wear with severe plastic deformation. The shallower scratches, circular grooves, and deeper grooves were identified at different conditions on the worn surfaces.

“…The optimization was performed using GRA and the results indicated that the sliding velocity was the most effective factor among the control parameters on dry sliding wear, followed by the reinforcement percentage, sliding distance, and contact stress. Soy et al [7] studied the wear behaviors of A360 matrix reinforced with SiC and B 4 C ceramic particles using Taguchi method. They have concluded that the type of the material, applied load, and sliding speed exert a great effect on the specific wear rate, at 48.13%, 31.83%, and 8.77%, respectively.…”

This work presents the application of hybrid approach for optimizing the dry sliding wear behavior of red mud based aluminum metal matrix composites (MMCs). The essential input parameters are identified as applied load, sliding velocity, wt.% of reinforcement, and hardness of the counterpart material, whereas the output responses are specific wear rate and Coefficient of Friction (COF). The Grey Relational Analysis (GRA) is performed to optimize the multiple performance characteristics simultaneously. The Principle Component Analysis (PCA) and entropy methods are applied to evaluate the values of weights corresponding to each output response. The experimental result shows that the wt.% of reinforcements (Q=34.9%) followed by the sliding velocity (Q=34.5%) contributed more to affecting the dry sliding wear behavior. The optimized conditions are verified through the confirmation test, which exhibited an improvement in the grey relational grade of specific wear rate and COF by 0.3 and 0.034, respectively.
