“…Thin, slightest depth and smooth grove were noticed for low load and speed condition and reverse trend for higher speed and load. The formation of oxide taken place with a raise in temperature with an increase in sliding duration [18,[22][23][24][25][26][27][28][29]. The plain and smooth wear tracks can observe in nanocomposites shown in figures 14(b) to (e), the MWCNTs reinforcement minimizes the adhesion and plough wear in comparison to LM6 [4,13].…”

The present work involved the production of Metal Matrix Composites (MMCs) of Aluminium Silicon (Al-Si) alloy reinforced with Multi Walled Carbon Nano Tubes (MWCNTs) using Powder Metallurgy (PM) process. MWCNTs with concentrations of 0, 0.25, 0.5, 0.75 and 1.0 wt% were used. Validation of dispersion nature, existence and chemically stable of MWCNTs carried out using Transmission Electron Microscope (TEM), X-ray Diffractometer (XRD) and Energy Dispersive Spectrum (EDS) for fabricated composites. Sliding wear investigations were investigated in accordance with the ASTM G99-95a standard. Test variables such as sliding distance, load and speed were examined. Under a given load with sliding distance, the wear rate was found to reduce by varying disc rotation speed between 250 to 750 rpm. The rate of wear is dropped suddenly with the increment in sliding distance from 500 m to 1000 m. However, for 1500 m sliding distance, the wear rate increased linearly for all nanocomposites. The reinforcement of 0.25 wt% and 0.5 wt% of MWCNTs shown lower wear resistance and further addition of 0.75 wt% MWCNTs shown enhanced wear resistance but the addition of reinforcement of above 0.75 wt% resulted in slightly higher wear rate. The wear resistance enhanced due to the excellent properties of reinforcement particles. The Scanning Electron Microscope (SEM) was used for identifying the kind of wear mechanism.

“…SiC offers various outstanding features, moreover including high hardness, high wear resistance and fair thermal stability. In addition, SiC does not react with aluminum at low temperatures, thus preventing unwanted brittle reactions at the interfaces [9,10].…”

“…Amongst the numerous synthesis techniques for aluminum matrix composites, powder metallurgy is the preferential option because it's low processing temperature which restricts the propagation of interface reactions [9,10]. Furthermore, uniform distribution of reinforcements in the matrix and development of almost netshaped products are added advantages of the powder metallurgy technique.…”

The wear behavior of Al-10 wt. %, SiC micro-x wt. %, SiC nano (x = 0, 1, 3, 5 and 7) hybrid nanocomposites were investigated. The effects of nano-silicon carbide (SiC) addition, the sliding distance and the applied load were studied in factorial design (5 × 3 × 2) of experiments. The influence of SiC, the sliding distance and the applied load were found to be 42.4, 42.3 and 11.3%, respectively. The wear resistance of the nanocomposite reinforced with 5 wt. % SiC nanoparticles was the best amongst all the synthesized nanocomposites. The worn surfaces and wear debris were analyzed using both scanning electron microscopy (SEM) and electron dispersive spectroscopy (EDS). Five different regression models were also developed to estimate the tribological behavior of composites with nano-silicon carbide (SiC) reinforcement, the sliding distance and the applied load as inputs. The accuracy of these models was evaluated using the five most commonly applied statistical indicators. The models were ranked according to their suitability for prediction using the Global Performance Indicator. The predicted values and experimental data showed a high degree of association. It was determined that the developed models could be used to predict wear behavior within the range of the investigation.

“…Major automotive and aerospace parts made up of nanocomposite material exhibits superior properties. Metal Matrix Nanocomposites (MMNCs) are the combination of certain metals (Al, Mg, and Cu) as a matrix material and ceramic particles (Carbides, nitrides, and oxides) as a reinforcing material [4][5][6]. The physical and mechanical properties of the nanocomposite vary from those of the alloys.…”

The present investigation aims to understand the wear behavior of aluminum LM4 matrix reinforced with the different weight percentage of tungsten carbide and tantalum-niobium carbide (0.5, 1.0, 1.5 and 2wt %) hard particles. Composite Specimens prepared by powder metallurgy route followed by cold pressing and hot sintering process. The wear tests were carried out using pin-on-disc machine under varying load (10, 20, 30 and 40N) speed (1, 1.5, 2 and 2.5m/s) and sliding distance (400, 600, 800 and 1000m) at room temperature. Characterization was done on nanopowders, developed composites and worn out surfaces of tested samples using Transmission Electron Microscopy (TEM), X-ray diffractometer(XRD), Scanning electron microscopy (SEM), Energy Dispersion Spectroscopy (EDS). The obtained results indicate that higher content of hybrid nanoparticles up to 2wt% in the composite reduces the wear rate up to 43.75% as compared with pure aluminum LM4 alloy.
