A Review on Sliding Wear Behaviour of Aluminium Matrix Composites with Hybrid Reinforcements for Automotive Applications

Abstract

The aluminium matrix composites, particularly with hybrid reinforcements are the advanced materials that have been widely used as a substitute material in the transport sector, to manufacture lighter-weight and higher-performance components. As these components are often subjected to sliding wear under working conditions, therefore several of these applications require enhanced frictional and wear resistance. The purpose of the current review is therefore aimed at highlighting the focus of the current research scenario, in the field of tribological behaviour of aluminium based hybrid composites, to explore the materials for automotive applications. A significant experimental data has been reported in this area, and it has been revealed that the materials possessing high wear resistance are associated with formation of a stable tribolayer on the wear surface and the fine equiaxed wear debris. The operating variables such as applied load, sliding distance and sliding speed, temperature, wearing surface hardness, reinforcement contents and morphology have been found as critical parameters in relation to the wear regime, encountered by the material during operation. An attempt has been made to present and review the various aspects relevant to sliding wear behaviour of aluminium alloys and the hybrid composites, with different combinations of reinforcements. Further, it has been found that the cost and the weight of the aluminium matrix composites can be considerably controlled, by addition of hybrid reinforcements, without compromising the tribological properties.

Fabrication characteristics and tribological behavior of Al/SiC/Gr hybrid aluminum matrix composites: A review

“…This phenomenon can be controlled by the addition of Gr particles in the Al/SiC composites, which smears the counterface and reduces the wear rate of the hybrid composites. This phenomenon was confirmed in the micrographs of the worn surfaces of Al/SiC/Gr composites, which revealed the presence of mild wear [76][77][78].…”

Characterization of hybrid aluminum matrix composites for advanced applications – A review

“…Moreover, the use of stir casting technique for fabrication of AMCs reduces the cost the composites, as it is economical, simple to perform and highly productive method [3,10]. Nowadays, there is growing concern in the production of HAMCs with better physical and mechanical properties [11,12]. Recent research investigations have revealed that agro/industrial waste materials such as fly ash, graphite, rice husk ash, etc., can be successfully used as a complementary reinforcement in AMCs [13][14][15][16][17].…”

Effect of heat treatment on mechanical and tribological properties of aluminum metal matrix composites

“…Aluminum MMCs are most popularly used composites because of its lightweight nature, high thermal conductivity, improved elastic modulus, and strength. 1 Aluminum alloy grades like LM25 were extensively used in automobiles because of their attractive characteristics such as good strength-to-weight ratio, high cast-ability, and good formability. LM25 alloy wheel rims of an automobile were tested under different load conditions, which resulted in optimized weight, shape with good factor of safety.…”
