“…And combining the surface morphology of both, we can obtain that the adhesive wear of the composites is less severe than that of the matrix. This conclusion is consistent with the results of Cao et al and Wang and Rack [8,9], who studied the wear properties of SiC-whisker and SiC-particulate reinforced aluminum composites. They found that the adhesive wear of composites was less severe than that of the matrix alloy.…”

The wear behavior of extruded nano-SiC particulates reinforced AZ61 magnesium matrix composites fabricated by ultrasonic method was investigated with wearing test machine, electronic balance, and scanning electron microscopy (SEM). The results show that, at the sliding speed of 0.5 m/s or 1 m/s, the extruded composites exhibit superior wear resistance over the matrix with the rise of wear load. At the high load, the softening and melting of composites are delayed to higher loads and speed because of their higher thermal stability.

“…Contrary to these findings, some other investigators [13][14] have reported reduced wear rates of the composites where the matrix alloy contained hard particles such as SiC, Al 2 O 3 , SiO 2 , Si 3 N 4 and glass. Of all the techniques available for preparing the composite, the liquid metallurgy route is the most popular one as reported by Ramesh et.al [15].…”

“…The oxidation rate increased with increasing the sliding velocity as a function of sliding distance. This may be because of the rise in interface temperature which softened the nanocomposites [35,36]. The wear loss at sliding velocity of 2 m/s in steps of 250 m at various normal loads on the pin is plotted in Figure 9(c).…”

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.
