“…Consequently, the hard asperities Tribological behavior, mechanical properties and microstructure of Al-12Si-ZrC composite prepared by powder metallurgy of the composites and the coefficient of friction of the ZrC nanoparticle-included matrix were reduced compared to pure Al. These aspects help in providing higher control over the coefficient of friction in the Al-12Si-xZrC nanocomposites [15]. For all the Al-12Si-xZrC nanocomposite samples the coefficient of friction increased with an increase in load and sliding distance [12][13][14].…”

Abstract. High-energy mechanical alloying method was used to prepare Al-12Si-xZrC (x = 0, 5, 10, 15 wt. %) nanocomposites. Cylindrical preforms were prepared with an initial preform density of 89% by using a suitable die and punch assembly. The preforms were sintered in a muffle furnace with an inert gas atmosphere at a temperature of 550°C, followed by cooling until room temperature has been attained. Scanning electron microscope (SEM) and X-ray diffraction (XRD) techniques were used to characterize the composites. Pin-on-disc wear testing machine was used to determine the tribological properties of the prepared composites. The results show that the wear loss reduced with increasing the reinforcement content and coefficient of friction increases gradually. Normally, solid state methods are used to produce composites with high mechanical properties, because these methods deliver a uniform distribution of reinforcing phase particle in the matrix material [6][7][8][9][10]. Some trials were conducted to fabricate Al-12Si-xZrC nanocomposites using different techniques, but the mechanical alloying method is a suitable technique to fabricate Al-12Si-xZrC nanocomposites. No attempt has been made to fabricate Al matrix composites reinforced with ZrC particles using the P/M method. In this present paper, an effort is made to study the outcome of wear behavior of Al-12Si-xZrC nanocomposites prepared with the mechanical alloying method. These composites were characterized using SEM and XRD. The wear behavior was calculated using the weight loss method. The worn surfaces and wear debris were characterized using SEM. Experimental procedure2.1. Materials. Aluminium and silicon with 99.5% purity and particle size of 44 µm were purchased from Metal Powder Company Limited, Thirumangalam, Tamilnadu, India, and the ZrC powder with a high, 99.9% purity and particle size of 400 nm was purchased from US Research Nanomaterials, Inc., USA. The individual powders were pulverized and mixed in a high-energy ball mill with ball-to-powder weight ratio of 20:1. The milling was done at a constant speed of 300 rpm in a wet medium with a presence of toluene to avoid oxidation and agglomeration. Scanning electron microscope images were used for the analysis of mixed powder particles. Fig. 1 shows the received powders of aluminium, silicon, and zirconium carbide. From the SEM images, it can be visualized that aluminium was spherical in shape, silicon was flattened and nano-zirconium carbide had a cubic crystal shape.

“…The Al 5083 based surface composite via FSP and reported the uniform distribution of reinforcement in the stir zone and good bonding properties between reinforcement and matrix material. The tribological studies showed that surface composite has the highest wear resistance and hardness [26]. [27] fabricated metal matrix composite via FSP and reported the more homogeneous dispersion of particles and fine equiaxed grains in the stir zone and improved hardness up to 55 % and wear rate of composite has reduced to 9.7%.…”

Friction stir processing (FSP) is solid state novel technique developed to refine microstructure and to improve the mechanical properties and be used to fabricate the aluminium alloy matrix composites. An attempt is made to fabricate AA6061/TiB2 aluminium alloy composite (AMCs) and the influence of process parameters like rotational speed, transverse feed, axial load and percentage reinforcement on microstructure and mechanical properties were studied. The microstructural observations are carried out and revealed that the reinforcement particles (TiB2) were uniformly dispersed in the nugget zone. The Tensile strength and Hardness of composites were evaluated. It was observed that tensile strength, and hardness were increased with increased the rotational speed and percentage reinforcement of particles. The process parameters were optimized using Taguchi analysis (Single Variable) and Grey analysis (Multi Variable). The most influential parameter was rotational speed in single variable method and multi variable optimization method. The ANOVA also done to know the percentage contribution of each parameter

“…FSP performed on 5083Al using nano-sized Cu particles showed higher tensile strength, ultimate tensile strength, elongation and hardness than the base metal [5]. On a work with hybrid MMC using Al5083 plate with SiC and MoS 2 particles, the hardness and wear resistance properties were improved by FSP [6]. Even dispersion of fullerene into A5083 matrix using FSP resulted in increased microhardness by promotion of grain refinement due to pinning effect and high hardness of fullerene particles [7].…”
