“…% of SiCp reinforced nanocomposites at sliding distance 3000 m, at 20 N normal loads were 0.26, 0.27, and 0.28, respectively. The lower friction coefficient was obtained at a large amount of sliding velocities and at higher sliding distances [38]. The variation of the friction coefficient was low because of the formation of the oxide layer on the worn surfaces at higher normal loads and sliding velocities [20].…”

The present study focused on the wear performance of AA6061/ SiCp (1, 1.5 and 2 wt. %) of nanocomposites at dry sliding condition. The nanocomposite specimens were fabricated through ultrasonic assisted stir casting technique. The wear experiments were conducted under normal atmospheric conditions using a pin-on-disc apparatus. Three different applied normal loads on nanocomposite pin (10 N, 15 N, and 20 N); at various sliding velocities of (1 m/s, 1.5 m/s, and 2 m/s); and at sliding distances of (1000 m, 2000 m, and 3000 m) were considered. The influences of applied normal load on nanocomposite pin, wt. % of SiCp reinforcement particles, sliding velocity, and sliding distance on both friction coefficient and wear loss were studied. The changes of wear loss and friction coefficient with varying applied normal loads, sliding velocities, and sliding distances were plotted. It was observed that the wear loss increased linearly with increasing sliding distance and sliding velocity. This was due to the increase of oxidation layer on the pin surface. The average friction coefficient at sliding velocity 1 m/s for 1 wt. % of SiCp, 1.5 wt. % of SiCp, and 2 wt. % of SiCp reinforced nanocomposites at sliding distance 3000 m, at 20 N normal loads was 0.29, 0.43, and 0.46, respectively. The average friction coefficient at 2 m/s sliding velocity for the same load and sliding distance was 0.26, 0.27, and 0.28, respectively. The increase of SiCp reinforcement in the matrix increased the friction coefficient due to its cubic crystal structure. The increase of sliding velocity and sliding distances reduced the friction coefficient. The worn surfaces of the samples were examined using SEM and EDX analyses. SEM micrograph analysis of the wear surfaces of the nanocomposites exhibited the abrasion wear and oxidative wear with severe plastic deformation. The shallower scratches, circular grooves, and deeper grooves were identified at different conditions on the worn surfaces.

“…The wear resistance of Mg1.11Al 2 O 3 composites were investigated by conducting pin-on-pin disc test on specimens and the Mg1.11Al 2 O 3 composite showed an improvement in the wear properties of 1.3 times at low speed of 1 m/s and 1.8 times at higher sliding speed as shown in Figure 2. Improved wear resistance was also observed with the addition of ZnO nanoparticles [38]. Recent studies reported reduced coefficient of friction and wear rate with the addition of nanoparticles such as carbon nanotubes and graphene [39] and in nanocomposite coatings reinforced with SiC [40] and Al 2 O 3 [41] for biomedical applications.…”

Magnesium is the lightest structural metal that can be used for engineering applications and its non-toxic nature makes it attractive for use as a biomedical implant. The judicious addition of nanoparticles to magnesium assists in enhancing multiple engineering properties that are critical for its widespread use and are superior to that exhibited by conventional micron-size particles containing composites. The ability to improve mechanical properties with the use of smaller volume fraction of reinforcements while keeping density low makes magnesium nanocomposites an attractive choice for lightweight engineering and bio-resorbable biomedical applications. In view of the exceptional response of magnesium in presence of nano-length scale reinforcements, an attempt is made in this paper to provide a brief review of characteristics of several magnesium nanocomposites illustrating the effects of ceramic and metallic reinforcements to enhance mechanical properties.

The role of metal matrix composites (MMCs) has gained huge momentum in various researches as well as in industrial applications due to their high stiffness and higher strength to weight ratio. It helps in achieving enormous weight reduction without compromising the strength of the material. In this study, a novel attempt was made to fabricate MMCs with martensitic stainless steel as matrix and titanium diboride (TiB 2 ) as reinforcement. The AISI 420 matrix with different weight percentages (1%, 2%, and 4%) of TiB 2 reinforcement was fabricated by vacuum induction melting technique (VIM). The aim of this study was to analyze the influence of TiB 2 particle addition on the mechanical and tribological properties of AISI 420 composites. X-ray diffraction studies revealed the presence of TiB 2 phase in the composite along with peak shifting and broadening of the steel matrix due to induced strain. Optical microscopy showed the distribution of TiB 2 particles in the matrix along with a significant amount of grain refinement of the composite due to the addition of TiB 2 . Microhardness results showed that the presence of TiB 2 improved the hardness with AISI 420/4%TiB 2 composite possessing the maximum hardness. Tensile test results indicated a significant improvement in the ultimate tensile and yield strength of the composite with the addition of TiB 2 . The wear tests were carried out on a pin on disc tribometer for various loads at a different sliding distance for steady sliding velocity. The dispersion of TiB 2 particle helped in achieving better wear resistance of the composites. Wear surface morphology was carried out to explore the wear mechanisms. Among the various wear mechanisms, abrasion and oxidation phenomena dominated in the composites. Taguchi optimization technique predicted that wt% of TiB 2 and applied load as influencing factors on the wear rate of the material.
