Bronze, an industrially relevant material, is always at a constant need for improvement in its properties. It should possess superior hardness, wear resistance and high tensile properties. The microstructure of the composite was characterized by using an optical microscope. The mechanical and tribological tests were carried out on the developed composite samples as per ASTM standards. It was observed that the hardness of the developed bronze composite increases with an increase in the reinforcement addition. The tensile properties were found to improve with addition of reinforcement particles into bronze matrix but, there observed a decrease in the ductility of the composite as compared to the regular bronze alloy. The wear rate of the developed composite was found to be low as compared to that of the regular bronze alloy

Tensile and wear properties of aluminium (Al) based metal matrix composites (MMCs) was prepared by added titanium diboride (TiB2) with in-situ technique by salt route. The salts used in this research were potassium hexafluorotitanate (K2TiF6) and potassium tetrafluoroborate (KBF4). Nanocomposite samples were prepared by casting technique associated with incorporating 3 and 6 wt.% of TiB2 into matrix of Al-6wt.%Cu. Instron and wear tests machine were used to characterize the tensile and wear Al-Cu alloys properties. Results showed that increase in TiB2 content gave the high properties of tensile and wear behavior. The study indicates that TiB2 particles have giving improvement the wear performance of the Al–6wt.%Cu alloy. For a constant load and sliding speed, the wear rate decreases as a function of amount of TiB2 in the composite. The wear rate decrease with increasing in wt.% TiB2 particles for the all loads applied. However, addition of TiB2 particle to the Al–6 wt%.Cu matrix has show the coefficient value of wear decreases regardless of applied load. Study of the wear surfaces both alloy and composites by optical microscope suggests that the improvement in wear resistance is mainly due to the formation of finer groove or debris by content of TiB2.

The modern development in the field of science and technology has created a demand for many advanced engineering materials. In recent days, aluminium related metal matrix composite is a probable material for many applications such as transport, aerospace, marine and automobile applications. In this paper, experiments were conducted on composite having various weight fractions of SiC and Al2O3particulates fabricated by stir casting method. Characterization studies were conducted on the Al 7075 alloy and composite samples to assess the hardness and microstructural properties. Final samples were tested for hardness using vickers hardness machine. Microstructure examination was conducted by optical microscope. Microstructure of the composite samples reveals the presence and homogeneous distribution of reinforcements in the Al 7075 matrix. The hardness of aluminium metal matrix composites was increased due to the addition of silicon carbide and alumina reinforcements.

This present study aims to investigate the dry sliding wear behaviour of tungsten disulfide (WS2) particle reinforced bronze matrix composite against surface hardened steel and to discover the optimum wear parameter values such as applied load, sliding distance, sliding velocity and volume fraction of reinforcement to reduce the specific wear rate. The composite specimens were fabricated by liquid metallurgy route by varying the volume fraction of solid lubricant particles and prepared as per American Society for Testing of Materials (ASTM) G99-95. The experiments were carried out based on Taguchi design of experiments technique with L27 orthogonal array. The wear tests were conducted in pin-on disc wear testing machine for different loads - 20N, 40N and 60N, sliding velocities - 2.09m/s, 2.62 m/s and 3.14m/s and sliding distances of 600m, 1200m and 1800m in unlubricated conditions. The significant influence of wear parameters on sliding wear, interactions and optimum combination of wear parameter values to minimize the wear rate were obtained by signal-to-noise (S/N) ratio and analysis of variance (ANOVA). The results demonstrated that inclusion of tungsten disulfide particles decreased the wear rate of bronze and also the increases in amount of secondary phase increase the wear resistance of composites. The effect of solid lubricant particle on interfacial temperature was also studied and reported. It was found that percentage of solid lubricant and load are the most significant factors influencing the friction and wear properties of composites. The results revealed that, WS2 particle reinforced bronze matrix composites were the potential component can be replaced for pure bronze products in wear resistance applications.

Properties Of Composites

In order to improve the wear resistance, Fe–Cr–C alloy and β-Si3N4 whiskers were chosen as the hard phases in bronze-graphite to prepare self-lubricating composite. Friction behaviors were tested with counter material 45# steel to evaluate the tribological properties of composites. The results indicated that Fe–Cr–C alloy and β-Si3N4 whiskers played different roles in composites. β-Si3N4 whiskers can obviously decrease the wear rate by excellent wear resistance. While the Fe–Cr–C alloy had better wettability with matrix, which improved the interfacial bonding and provided a continuous wear resistance. Moreover, Fe–Cr–C alloy also played a role in maintaining the friction coefficient stability, and this effect was more significant in the conditions of high rotational speeds. The composite containing 12.5 vol.% β-Si3N4 whiskers and 2.5 vol.% Fe–Cr–C alloy in this research showed good friction performance.

Metal matrix composites (MMCs) have proved their viability as good alternatives to conventional alloys in high strength and stiffness application in industries like automobile, aerospace and mineral processing. Al metal matrix composites (MMCs) are being considered as a group of advanced materials for their lightweight, low coefficient of thermal expansion, and good wear resistance properties. The optimization of parameter has been done by using different techniques like Taguchi, DOE and their results were verified by ANOVA. Signal-to-noise ratio and Analysis of variance (ANOVA) were used to investigate the influence of parameters on the wear rate. Based on various papers the conclusion of this review paper is to study the influence of applied load, sliding speed and sliding distance on the various parameter such as optimum wear and co-efficient of friction of Al alloy-B4C composite to enhance the quality of product and suggest the best combination of wear parameter which helps to reduce the wear of product with the help of Taguchi method. The wear resistance of the composite was found to be considerably higher than that of the matrix alloy and increased with increasing particle content. The major observation based on reviewed papers is that the major factor in determining the wear rate is load applied followed by distance and sliding velocity whereas distance affects the coefficient of friction to a large extent followed by load and sliding velocity.
