“…With increase in sliding distance, the asperities deform and decrease the wear rate [2,3]. The deformation of material results in strain hardening of the matrix which further reduces the wear rate [ 10]. Further, the gap between asperities is filled by the debris formed during the wear test.…”

“…Some auto-components like pistons, cylinder liners, brake discs, brake drums etc are processed using AMCs [2,8,9]. AMCs are generally stir cast with ceramic particle reinforcements of SiC, TiC, B 4 C, Al 2 O 3 , TiB 2 etc [6,7,10]. Most of the research to improve the wear characteristics of AMCs has concentrated on reinforcing the aluminium matrix with synthetic ceramic particles like SiC, TiC, B 4 C, Al 2 O 3 , TiB 2 etc [2-4, 6, 7, 10].…”

The present work compares the dry sliding wear characteristics of sillimanite reinforced and rutile reinforced LM27 aluminium alloy based composites prepared by stir casting process. Particles in the size range of 1-32 μm were added in 5, 10, and 15 wt%. Microstructure, nanohardness, coefficient of friction, and wear rate characteristics were evaluated. Optical microscopy revealed uniform distribution of both sillimanite and rutile particles in the matrix. The hardness of sillimanite reinforced composites was higher than rutile reinforced composites. Further, the wear resistance of sillimanite reinforced composites was superior to rutile reinforced composites. However, coefficient of friction values of sillimanite particle reinforced composites were higher than the rutile particle reinforced composites. SEM-EDS analysis of wear track and wear debris revealed that abrasive wear and adhesion/delamination mechanisms were responsible for the wear of composites at low and high applied load conditions respectively.

“…The authors found that wear rate and friction coefficient decreased accordingly with the increase in wt% of grapheme nano particles. Yogesh et al [9] investigated the dry slippery wear analysis of AA6061 based composites reinforced separately with red mud, SiC and Al 2 O 3 particles using pin-on-disc tribometer. They examined that wear rate decreased with increase in wt% of SiC and Al 2 O 3 in the matrix, but the wear rate of red mud reinforced composite decreased upto 7.5 wt% only and increased beyond 7.5 wt%.…”

Abstract--The drift of research work from monolithic aluminum alloy to composite materials like Metal Matrix Composites (MMC's) is due to the world-wide proviso for economical, high working performance and superior quality materials. Metal matrix composites especially aluminum matrix composites (AMC's) due to their excellent strength with respect to their weight, superior wear resistance, economical and high corrosion resistance are extensively produced and utilized in several applications like, architectural components, structural applications, aerospace, automobile industry, ship building and many sports items and electrical and electronic components. The reinforcements like SiC, B 4 C, Al 2 O 3 , TiB 2 , Red mud, Graphite, Fly ash, and Coconut ash etc. can be easily incorporated as reinforcement agents in the molten melt by employing the economical and widely used stir casting technique, which improves strength, stiffness, fatigue, hardness, wear and creep properties of the AMCs. This paper gives an overview of mechanical, microstructural and wear performances of aluminum centered metal matrix composites produced by stir casting process reinforced with single and multiple types of reinforcements. The problems like reinforcement-metal matrix bonding, distribution of particles, wettability of reinforcing particles and agglomeration phenomenon are discussed in this paper. The effect of various reinforcement particles on aluminum matrix composites on mechanical properties like uts, ys, stiffness, hardness, fatigue, % E, wear and on resulting microstructure is discussed. The Modified and dual step stir casting technique for the fabrication of AMCs is also discussed in this paper. Keywords: Aluminum matrix composite (AMC), stir casting, reinforcement, mechanical properties, wear behavior I. INTRODUCTIONMetal based matrix composites reinforced with ceramic agents have a wide range of applications in aerospace, automobile, structural components and defense sector. Monolithic aluminum alloys have limitations in achieving good combinations of mechanical properties like strength, toughness, stiffness, wear resistance and density. Metal matrix composites are produced to overcome these shortcomings and to encounter the worldwide requirement for light weight materials with higher specific strength, corrosion resistant, high stiffness and excellent wear resistant properties [1][2]. The properties of aluminum alloy like low density, light weight, easy processing technique and fine engineering characterstics favored it as matrix material in MMC's [3]. The aluminum matrix series like AA2xxx, AA5xxx, AA6xxx, and AA7xxx have numerous applications in aerospace, defense instrument, architectural and structural components, automobile, sports good, and ship building [1][2][3][4].For the fabrication of metallic matrix composites several type of manufacturing methods are employed. The choice of appropriate manufacturing method highly alters the resulting composite microstructure, dispersion of ceramic agents, interfacial bonding betwe...

“…Unlike the synthesis of these ceramic particles need the controlled chemical environment at elevated temperatures, red mud particles are produced from industrial waste as a byproduct which facilitates energy saving and low cost [4]. Moreover, the particle size of red mud particles is available in the nano-scale regime (50-200 nm) which tends to enhance the strength and tribological behavior of the composites [5]. In general, red mud is one of the most abundant insoluble solid waste resulting from mineral processing of bauxite ore to produce alumina.…”

The present study aims at investigating the dry sliding wear behavior of Al-based 6082 metal matrix composites (AMMCs) reinforced with red mud particles by pin-on-disc configuration. AMMCs were fabricated with three different weight fractions of red mud particles ranging from 2 to 6% by using the stir-casting method. The friction coefficients and volumetric wear rates were continuously evaluated under normal loads of 10-30 N and sliding speed of 1.5 m s −1 for the constant sliding distance of 1000 m. Microstructural analysis indicated that red mud particles are more or less uniformly dispersed throughout the Al matrix with minimal agglomeration. Experimental data shows that microhardness and tensile strengths of both the as-cast and heat-treated composites are steadily improved by increasing the amount of reinforced red mud particles but at the cost of ductility. Analysis of worn surfaces revealed that delamination and abrasion are dominant wear mechanisms for the case of the heat-treated composites are whereas the adhesion wear mechanism for the base alloy. The composite containing 4% red mud particles experienced the lowest wear rate at a normal load of 30 N and sliding speed of 1.5 m s −1 as compared to other composites including the base alloy. While the composite with 2% red mud particles shows the lowest friction coefficient, base alloy exhibited the highest friction coefficient.
