“…Hogan and Song [10] 3 studied the effect of wear tests on subsurface modifications of wear tracks and found that the effect of wear tests manifested in the cross-section through three regions; region-I: tribo-layer, region-II: reorientation of the reinforcing particles bent towards the wearing direction and region-III is unaffected material. Panwar et al [11] also studied dry sliding wear of hypoeutectic Al-Si alloys incorporated with different size of ZrSiO4 particles at different temperature. They observed that the incorporation of two sizes of reinforced particles showed better wear performance than a single reinforced particle in Al-Si alloys.…”

“…An increase in microhardness has been observed with the increasing size of ZrSiO4 but the wear rate also increases with increasing the size of ZrSiO4 particle [11]. Villaseñor et al [4] have interpreted the influence of SiCp on microstructure and wear performance of cast Al-Si-Fe/SiCp composites.…”

“…Tribological studies of AMCs with different nature, size, and amount of reinforcements on various Al-Si alloys are available in the literature [7][8][9][10][11][12][13][14][15][16]. Though, the research work reported on the nonlubricated dry sliding wear performance of LM27 alloy with fine and coarse size SiCP reinforced is limited.…”

In this study, an investigation on the influence of In-situ tribo-oxide-layer on non-lubricated tribological behaviours of LM27/SiCp composites was carried out at different applied loads. The variations in wear performance and microstructure of brake lining friction material (LM27) with the addition of different amounts and sizes of SiCp are explored. For this purpose, LM27/SiCp composite materials were manufactured by stir casting route varying the amount of particle reinforced from 3wt.% to 12wt.% with a different size range (fine: 1-20µm and coarse: 106-125µm). Non-lubricated dry wear tests of LM27/SiCp composites samples were trialled at different loads from 9.8N to 49N by using a pin-on-disc machine system. At a contact pressure of 0.2-1 MPa, LM27/SiCp composites with 12wt.% reinforcement showed a lower coefficient of friction than other composites. In-situ formation of oxide layers on the contact region of the specimen supports the self-lubrication during the wear test, which is responsible for better wear performance of LM27/SiCp composites. However, these study portraits that composite with 12wt. % fine size SiCp exhibits better wear performance in comparison to the other developed composites.

The mechanical properties and microstructure of aluminum matrix composites containing of zircon (10, 15 and 20 wt.%) as a reinforcement particles and cobalt additive (1, 1.5 and 2 wt.%) were investigated. The aluminum matrix composites were prepared by powder metallurgy technique and sintered in both conventional and microwave furnaces at temperatures higher than the melting point of aluminum. The results revealed that the density and mechanical strength of aluminum were increased by introducing zircon and cobalt particles. The maximum strength was obtained by adding 10 wt.% zircon sintered in microwave furnace at 950°C. The phase analysis and scanning electron microscopy of sintered composites were examined and found some interesting data about intermetallic compounds.

“…They observed that combination of 3% fine and 12% coarse particle reinforced composite exhibits better wear resistance. Panwar et al (2014) have carried out a detailed study of ceramic reinforcement of different size ranges in the matrix of LM13 alloy on the friction and wear behaviour. Kumar et al (2013) have studied the role of particle size for high-temperature application of ZrSiO4-reinforced aluminum-based LM13 alloy composite as a bearing material.…”

Address correspondence to Thiagarajan Rajmohan. www.tandfonline.com/upstMetal Matrix Nano Composites (MMNC) consist of a metal matrix reinforced with nano-particles featuring physical and mechanical properties very different from those of the matrix. Especially carbon Nano tubes (CNT) can improve the matrix material in terms of wear resistance, damping properties and mechanical strength. The present investigation deals with the synthesis and characterization of aluminium matrix reinforced with micro B4C particles, and Multi Wall Carbon nano Tubes (MWCNT) which have been prepared by powder metallurgy route. Powder mixture containing fixed weight (%) of B4C and different wt% of MWCNT as Downloaded by [UNSW Library] at 11:05 12 August 2015 2 reinforcement constituents that are uniaxial cold pressed and later green compacts are sintered in continues electric furnace. Microstructure and Mechanical properties such as micro hardness and density are examined. Micro structure of samples has been investigated using scanning electron microscope(SEM). X-ray Diffraction(XRD),Energy dispersive X-ray(EDAX), Atomic Force Microscope(AFM) and Transmission Electron Microscope (TEM). TEM microstructure of the nano composite shows the homogeneous dispersion of MWCNT in the Aluminium matrix. The results indicated that the increase in wt % of MWCNT improves the bonding and mechanical properties.
