“…Thus, the addition of TiO 2 particles improves the wear resistance of the magnesium matrix in Mg-TiO 2 composites. Also, the wear loss curves obtained for all the samples develop in a non-linear manner [25][26][27]. Therefore, it is inferred that the wear loss does not vary proportionally with respect to a change in load.…”

SummaryIn the present study pure magnesium was taken as a base metal which is reinforced with various weight percentages of TiO 2 (2.5, 5, 7.5, 10 % wt). This is done through a vacuum stir casting route with argon as a shielding gas to prevent oxidation. The prepared samples were machined using the Electric Discharge Machining (EDM) to achieve accurate dimensions for the study of tribological properties. A computerized pin-on-disc machine is used to study the dry sliding wear behaviour of the Mg-based composites. Wear losses were calculated using a variety of load parameters (10N, 15N, 20N, and 25N), sliding velocities (1 m/s, 1.5 m/s, and 2.0 m/s) and the weight percentage of the reinforcement. The results proved that the wear loss increased with an increase in the load, and decreased with an increase in the sliding velocity. The wear resistance is improved with an increase in the percentage of reinforcements in the matrix. The morphology and distribution of reinforcements were analysed by means of Scanning Electron Microscopy (SEM) and Energy-Dispersive X-ray (EDX) spectroscopy, respectively. The results revealed a uniform distribution of TiO 2 particles throughout the magnesium matrix in the Mg-TiO 2 composites.

“…Fig. 8.25 The effect of normal load on friction coefficient [13,14,71,[101][102][103][104] Several studies have shown that an increase in sliding speed leads to an increase in wear rate, especially at higher sliding speed ranges. For instance, Al-Fe and Al-SiC composite illustrate an initial decrease in the wear rate at lower sliding speeds; however, these composites showed a sharp increase in the wear rate at higher sliding speeds (see Fig.…”

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.

The influence of titanium diboride (TiB 2 ) loading on the dry sliding wear characteristics of aluminum 6063 matrix alloy-titanium diboride (Al/TiB 2 ) composite materials has been assessed using a pin-on disc wear tester at different loads. The composites with 5 and 10 wt% of fine TiB 2 particles were fabricated using stir casting technique. For comparison, as-cast of the base alloy were made under the same processing applied for Al/TiB 2 composites. The hardness of the composite materials was measured using Brinell hardness tester. Scanning electron microscopy (SEM) was used to analyze the wear surfaces of samples. The results indicate that fine TiB 2 particles markedly improved the wear performance of the aluminum 6063 matrix alloy. The coefficient of friction decreases with increase in the amount of TiB 2 , but this effect was more pronounced in dry sliding. Hardness of composites increased with increasing TiB 2 loading. The wear rates increase with increase in load and dependent upon TiB 2 loading in the base alloy. Among the composites tested, Al/TiB 2 composites containing 10 wt% TiB 2 exhibited superior wear resistance over the base alloy and 5 wt% Al/TiB 2 composites. These observations were correlated in terms of the TiB 2 loading in base alloy which resulted in the variations of the hardness.
