Aluminum/graphite (Al/Gr) composites have been used as self-lubricating materials due to the superior lubricating effect of graphite during sliding. This paper summarizes various tribological aspects of self-lubricating aluminum composites. The influence of various factors such as (a) material factors, graphite size and volume fraction, and (b) mechanical factors, applied load and sliding speed on the tribological properties of self-lubricating aluminum composites, is discussed. Furthermore, the tribological properties of selflubricating composites as a function of these parameters and the active wear mechanism involved in various systems are discussed. Bringing self-lubricating composites into different operating systems is a solution to reduce the use of external toxic petroleum-based lubricants in sliding contacts in a way to help the environment and reduce energy dissipation in industrial components for strategies toward sustainability and energy efficiency.

“…Figure 8.8 shows a general variation of wear rate with volume fraction of reinforcement in the composites. The data for this plot was obtained from different references [22,38,[62][63][64][65][66]. As indicated earlier, the wear rate of the composite decreases with increasing volume fraction of the reinforcement particles.…”

“…The figure shows an increase in wear rate of the MMCs with an increase in the size of the reinforcements [91]. Nevertheless, some studies show a critical particle size of reinforcements at which the wear rate of the composites changes considerably [66,90]. Figure 8.17 shows the wear rate of the aluminum matrix composites reinforced by SiC particles (2-167 μm).…”

“…It has been observed that a critical particle size is important to determine the wear behavior of the composites. The 20 μm SiC particle size is the critical size for this composite at which the minimum wear rate is obtained [66]. The effect of particle size of reinforcement on the wear rate of the composite [66] The effect of reinforcement particle size on the coefficient of friction has been studied.…”

Metal matrix composites (MMCs) are an important class of engineering materials that are increasingly replacing a number of conventional materials in the automotive, aerospace, marine, and sports industries due to their lightweight and superior mechanical properties. In MMCs, nonmetallic materials are embedded into the metals or the alloys as reinforcements to obtain a novel material with attractive engineering properties, such as improved ultimate tensile strength, ductility, toughness, and tribological behavior. In this chapter, an attempt has been made to summarize the tribological performance of various MMCs as a function of several relevant parameters. These parameters include material parameters (size, shape, volume fraction, and type of the reinforcements), mechanical parameters (normal load and sliding speed), and physical parameters (temperature and the environment). In general, it was shown that the wear resistance and friction coefficient of MMCs are improved by increasing the volume fraction of the reinforcements. As the normal load and sliding speed increase, the wear rate of the composites increases and the friction coefficient of the composites decreases. The wear rate and friction coefficient decrease with increasing temperature up to a critical temperature, and thereafter both wear rate and friction coefficient increase with increasing temperature. The nano-composites showed best friction and wear performance when compared to micro-composites.

Copper-coated silicon carbide (SiC) particles have been developed to improve the strength and wear resistance of Al-Si matrix composites, which are utilized in brake pads and, hence find applications in aerospace and automobile industries. Copper-coated SiC powder is prepared by electroless plating and is characterized by scanning electron microscopy and X-ray diffraction. Copper-coated SiCp reinforced Al-Si composites are prepared by a powder metallurgy method, and their microstructures and properties are compared with those of Al-Si and Al-Si-Cu matrix composites reinforced with SiCp without copper coating. Our results show that the copper-coated SiC p -reinforced Al-Si composite exhibits advantageous mechanical properties and better frictional wear resistance.
