“…(5) it is clear that the specific wear rate decreases as the speed, load and weight fraction of Al 2 O 3 increase. Similar findings were also observed by Dharmalingam et al [18]. From Table 4, the model value of 305.71 indicates the model is significant and the lack of Fit F-value of 6.60 implies the lack of fit is not significant for specific wear rate.…”

“…8, as load increases the specific wear rate decreases. This is because the hard Al 2 O 3 particles present in the composites increase the thermal stability of the matrix, which ultimately results in improved wear resistance at higher loads [18][19][20][21]. The decreasing nature with respect to load indicates the improved wear resistance performance at higher loads.…”

We consider the influence of alumina (Al 2 O 3 ) particles on mechanical and tribological properties of aluminum hybrid metal matrix composites (MMC). Various weight fraction of Al 2 O 3 (5, 10 and 15%) and constant weight fraction of graphite (5%) were used to fabricate composites by stir casting method. The effect of Al 2 O 3 content on hardness, density and specific wear rate is evaluated. A wear test was performed using central composite design matrix on a pin-on disc apparatus at room temperature for constant sliding distance of 1000 m. The sliding speed, load and weight fraction of Al 2 O 3 were the process variables. The results show that the hardness and density increase with increase in Al 2 O 3 content. From the analysis of variance (ANOVA), load is the dominant factor that affects the specific wear rate of hybrid composites followed by speed and weight fraction of Al 2 O 3. Based on desirability approach, the improvement in the wear resistance of the composites became more prominent at high speed, high load and high weight fraction of Al 2 O 3 . The worn surface of the pin was examined using scanning electron microscope (SEM) which indicates that the wear mechanism of composites is mostly abrasive wear followed by oxide wear.

“…The observation was found by other researchers and in their study of dry sliding friction and wear behavior of aluminum-alumina composites using Taguchi technique [10]. Dvivedi et al, (2012), also claimed the same finding when studying the tribological characteristics of Al 6063-SiCp metal-matrix composite under reciprocating and wet conditions [11].…”

Carbon nanotube (CNT) reinforced aluminium (Al) nano-composites were produced using powder metallurgy route with different weight percent of CNT in to the Al matrix. The wear behaviour of CNT-Al nano-composite was studied using a pin-on-disc tribometer against AISI4340 steel disc. Experiments were conducted using different sliding velocities of 0.5, 0.65 and 0.8 m/s and a normal load of 5, 7.5 and 10 N. Design Expert (DOE) version 6.0.8 was used to optimize the process variable for wear and friction test of the developed CNT-Al nano-composite using face centered central composite design based on response surface methodology and confirmed that 1.5 wt% was the optimum CNT-Al nano-composite formulations. The result showed that higher hardness value of the material showed a lesser wear rate and better wear resistance. The result showed that the wear rate of the developed nano-composite decreased with the increasing of CNT content but up to 1.5 wt% CNT into the nano-composite. The wear rate values varied from 2-0.6 x10-3 mm3/m (2, 0.2, 0.17. 0.3 and 0.6 mm3/m x10-3 for 0 wt%, 1 wt%, 1.5 wt%, 2 wt% and 2.5 wt% CNT respectively). These results also showed that the rate of wear decreases with the increase in normal load and sliding speed. DOE confirm the accuracy of the experimental result for the evaluation of the developed CNT-Al nano-composite.

“…At low sliding speed, the surfaces of both the PEEK composites and the steel counterpart were rough and thus strong ‘interlocking’ took place, resulting in a high friction coefficient. 26 As the wear process continued, the steel counterparts and the PEEK composite specimens were smoothened due to the transfer film formed on the surface of the counterface. Consequently, lower COFs were achieved when a steady wear stage was reached.…”

Polymer matrix composites have revealed enormous potential to substitute metal components in a wide variety of applications because of their self-lubrication properties, lightweight and resistance to wear, corrosion and organic solvents. However, additional upgrading in their properties is still essential. The endeavour of this research was to assess the effect of the material type and the morphology of multiwalled carbon nanotubes (MWCNTs) on the wear performance of poly-ether-ether ketone (PEEK) matrix composites. The MWCNT-filled PEEK matrix composites were prepared using melt mixing technique. The wear behaviour of reinforced MWCNT-filled PEEK composites was studied using the pin-on-disc apparatus under dry sliding conditions at different applied loads, sliding speeds, temperature and wt% MWCNTs. Experiments were conducted using response surface methodology (RSM)-based central composite design. The specific wear rate and coefficient of friction were considered as wear performances of MWCNT-filled PEEK matrix composites. The second-order models are developed to optimize the wear parameters using the genetic algorithm technique. The morphologies of the worn surfaces were observed by scanning electron microscopy.
