“…It seems that in the wear process these hard ceramic nanoparticles in interface of silicon and aluminum matrix protect the surface of silicon from direct contact with abrasive agent. 48 The SEM image of wear surface of nanocomposite is illustrated in Figure 10. Generation of cavities due to delamination of surface materials, tearing of surface of materials and abrasive grooves can be seen in Figure 10(a) to (c).…”

In the present study, regarding the theoretical and practical aspects of nanoparticle capture in liquid-state processing of aluminum composite, different volume fractions of [Formula: see text] and [Formula: see text] nanopowders were incorporated into aluminum alloy via stir casting method. Hardness and sliding wear test were carried out to evaluate the mechanical properties of composites. The effects of wear load and reinforcement content on wear rate and friction coefficient of composites were examined. Microstructural studied showed that particle distribution in A356-[Formula: see text] composites was more favorable than that of the A356-[Formula: see text] samples. Results showed that nanoparticles were partially captured by aluminum matrix. With an increase in reinforcement content the amount of porosity and rejected nanoparticles increased. Regarding the wettability features of particles, the amount of introduced [Formula: see text] powders was higher than that of [Formula: see text] particles. A356-[Formula: see text] composites showed higher mechanical properties compared with those of A356-[Formula: see text] samples. Significant improvements in hardness and wear resistance were obtained in A356-1.5 vol.% [Formula: see text] composite. It was observed that the friction coefficient of the composites was lower than that of the non-reinforced alloy. With an increase in normal wear load, wear rate of composites increased and friction coefficient of reinforced samples decreased. Study on surface morphology of the worn surfaces showed both of the mild and sever wear mechanisms. The depth and number of grooves in worn surface of composites decreased with introduction of nanoparticles into matrix. The presence of oxide layers was detected on worn surface. Iron trace was observed in wear debris of samples.

“…To study the wear behavior of composites at high temperatures, Kumar et al [48] fabricated five composites, namely A, B, C, D and E with different compositions of zircon sand and silicon carbide particles were used as hybrid reinforcements (up to 15 mass%), to obtain required wear properties [49,50]. The microhardness of these composites with different combinations of dual reinforcements has been presented in Table 3.…”

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.

Panwar et al Analyzed the wear debris and characteristics of a stir-cast LM13/Zr composite at high temperatures and reported thatthe zircon reinforcement in the Al-12% Si alloy MMC results in an unvarying particles distribution, showing a better matrix-reinforcement bonding [115].

The growing demand for composite materials with improved properties is attracting a lot of attention from industries such as automotive, aerospace, military, aviation, and other manufacturing. Aluminium metal matrix composites (AMMCs), with various reinforcements such as continuous/discontinuous fibers, whiskers, and particulates, have captured the attention due to their superior tribological, mechanical, and microstructural characteristics as compared to bare Al alloy. AMMCs have undergone extensive research and development with different reinforcements in order to obtain the materials with the desired characteristics. In this paper, we present a review on AMMCs produced through stir casting routes. This review focuses on the following aspects: (i) different reinforcing materials in AMMCs; (ii) microstructural study of reinforced metal matrix composites (MMCs) through stir casting. Both reinforcing micro- and nanoparticles are focused. Micro- and nanoreinforced AMMCs have the attractive properties of combination such asthe low-weight-to-high-strength rati and, low density; (iii) various tribological and mechanical properties with the consideration of different input parameters; (iv) outlook and perspective.
