A Short Review on Al MMC with Reinforcement Addition Effect on Their Mechanical and Wear Behaviour

Abstract

Advanced mechanical and wear properties and applications of composites with bases of light weight metals have led to the need of aluminium (Al) metal matrix composites (MMCs). In today's time aluminium (Al) metal matrix composites (MMCs) are considered the most potential material for structural and functional applications. Composite materials with aluminium matrices are used in defence, aerospace, automotive and aviation, thermal management areas. Beneficial properties with reduced prices have enlarged their applications. To obtain desired physical and mechanical properties like high hardness, high strength, high stiffness, high wear, abrasion and corrosion resistance Al is reinforced with different metallic, non-metallic and ceramic elements. Al MMCs are used to make piston, connecting rod, engine cylinders, disc and drum brakes where wear has a great role in the functioning of these components as excessive wear of the mating components sometimes leads to catastrophic failures. Improvement of mechanical, especially tribological properties of hybrid composites were provided by the use of certain reinforce materials such as SiC, Al 2 O 3 and graphite. Hence the present chapter presents a review on aluminium metal matrix composites (MMCs) reinforced with different particulate, whisker, fibres reinforcements highlighting their effect on physical, mechanical and wear behaviour of Al MMCs.

Effect of short carbon fiber/SiC on tribological properties of aluminium matrix hybrid composites

“…The increasing concentration of stiff CF in the matrix distributes the indentation load and helps in hindering the movement of dislocation by acting as an obstruction to matrix dislocation and hence dispersion hardening takes place in the composite [17]. A similar type of results was also reported in the literature [5,17,18].…”

Corrosion of Aluminum Metal Matrix Composites: A Review of the Effect of Manufacturing Processes, Processing Routes and Secondary Phases

“…1 Schematic diagram of composite materials [7] Basic problem of Al/SiC Al alloy 6061, 2024 and 7075 augmented with SiC are some of the major composites utilized in aeronautical, automobile, energy generation and consumer industries which expose them to corrosive anions. Most research on composites is aimed at its mechanical and metallurgical properties, and processing directions with minimal portion focused on their corrosion resistance [9][10][11][12][13][14]. The binary configuration of composites exposes their vulnerability to accelerated corrosion as against their homogeneous counter-parts [15][16][17][18][19].…”

Mechanical and tribological behavior of Al composites containing varying beryllium aluminum silicate and constant CeO2

“…Cerium oxide has a unique property of having stability in chemical attack and high temperature [53,54]. Al MMCs are used in different areas of industries for making different machine components which are prone to corrosion [52,[55][56][57][58][59][60]. To protect them from corrosion anti-corrosive coatings of zinc chromate is done which is in general toxic in nature and hazardous to the environment.…”
