Aluminum alloys are used frequently in aerospace and ship building industry. Due to poor wear and corrosion resistance, conventional aluminum alloys are replaced by metal matrix composites (MMC). Aluminum alloy matrix reinforced with ceramic particles (TiB 2 ) has importance in industry where components slide each other. The main task is to produce MMCs with low cost effective way to meet the requirement. In this study, an attempt is made to produce AA6061/TiB 2 MMCs with different volume fractions of ceramic particles using friction stir processing technique. The dry sliding wear behavior of composites was investigated using pin on disc method. The lowest wear resistance has obtained for 8% composite. The corrosion of composites was analyzed by salt spray method. It was found that wear and corrosion resistance was increased with increase of reinforcement which was higher for 8% composite.

“…The weight loss curves show a fluctuation in its trend, revealing that the passive films formed are not stable for longer exposure times. This is due to the repeated film formation and its breakdown after exposure to HCl solution [17]. The weight loss in composites is lower than that of base alloy due to the presence of reinforcement particles that prevent the composites from attack by the corrodants.…”

advantages of these MMCs are reduced processing cost compared to other matrix materials such as magnesium and titanium [4] as well as ease of fabrication [1,5]. Mechanical properties and corrosion behaviour of Al MMCs are very important requiring consideration in composite material design to ensure material reliability in applications such as aerospace, defence, automotive and sports [1]. In addition to use of Al MMCs in various corrosive environments, a detailed study has to be carried out on aluminium-based alloys and their composites [6]. From the available literature, it is found that the mechanical properties and corrosion behaviour of these composites are influenced by several factors such as the type, size and distribution of reinforcement added, method used for preparation of the composite, alloy composition and the interface between the matrix and reinforcement [7,8]. Any change in the above parameters can significantly alter the properties of these composites [8,9]. These properties are also influenced by the presence of heterogeneities such as reinforcement, voids, secondary phase precipitates and interaction products [9]. Although Al MMCs with different combinations of reinforcements have been widely investigated, only limited literature is available on zircon and alumina reinforced MMC. The choice of zircon and alumina as reinforcement is believed to significantly improve the mechanical properties and corrosion behaviour of Al-alloy-based hybrid composite. Hence in this work an attempt has been made to study the microstructure, mechanical properties and corrosion behaviour of this new combination of hybrid composite. AbstractIn the present study, the effect of reinforcement on microstructure, mechanical properties and corrosion behaviour of aluminium-silicon-magnesium (Al-Si-Mg) alloy matrix hybrid composites reinforced with varying amounts of zircon and alumina has been investigated. Hardness and room temperature compressive tests were performed on Al-Si-Mg alloy as well as composites. Hardness and compressive strength was found to be higher for composites containing 3.75 % ZrSiO 4 + 11.25 % Al 2 O 3 . Similarly, Al-Si-Mg alloy and its composites were studied for corrosion behaviour in 1 N HCl corrosive media. The weight loss of all the composites was found to decrease with time due to the formation of passive oxide layer on the sample surface. The results obtained indicate that composites exhibit superior mechanical properties and corrosion resistance compared to unreinforced alloy.

“…Metal matrix composites (MMCs) have been noted to offer such tailored property combinations required in a wide range of engineering applications [1,2]. Some of these property combinations include: high specific strength, low coefficient thermal expansion and high thermal resistance, good damping capacities, superior wear resistance, high specific stiffness and satisfactory levels of corrosion resistance [3][4][5].…”
