“…The diffraction peak of 2θ at 32 corresponds to the standard value of magnesium as by previous research study conclusions made by Jaroslav Capek 34 and Soorya Prakash. 19 Clear peaks of Mg, CeO 2 of magnesium alloy matrix were observed in all the samples. The results show eight phases in all samples, one resulting in the cerium oxide phase and the remaining part containing magnesium.…”

In this study, an attempt is made in producing composite materials by reinforcing cerium oxide with magnesium matrix. Very limited research has been carried out by using cerium oxide as a reinforcement through powder metallurgy technique. Hence the effects of reinforcing cerium oxide on microstructure, mechanical and wear properties in magnesium matrix are studied. The weight percentage of the reinforcement is varied by 3, 6, 9 and 12. Microstructural, mechanical properties like density, microhardness and compression strength and wear properties were studied for the fabricated composites. Scanning electron microscope with energy dispersive X-ray analysis (EDX) and X-ray diffraction (XRD) exhibited uniform distribution of cerium oxide and its presence in the matrix, respectively. Line scan mapping was also carried out on the samples to identify the particles present at that particular region in the matrix. The increase in cerium oxide has reduced the density but increased porosity in the composite materials. The microhardness and compressive strength have gradually increased with an increase of reinforcements. The microhardness has increased up to 40% and compressive strength has increased from 83 to 176 MPa for 12% cerium oxide, respectively. The wear resistance has also increased with an increase in reinforcement and a 28% increase in wear rate was inferred. SEM images of the worn surface exhibited good grain refinement of ceramic oxide in the matrix.

“…The composite sample and the disc were cleaned to remove impurities using acetone before the test starts. The wear test was carried out at various load ranges such as 5, 10, 15, and 20 N and at varying sliding distant from 500 m to 2000 m [8]. The sliding speed is also varied from 0.5 m/s to 2 m/s.…”

This work summarizes the tribological and corrosion behaviour of Co-Gr nanocomposites. The Co-Gr nanocomposites are synthesized using highenergy ball mill and compacted into cylindrical pellets by hydraulic pressing. The composites are characterized using SEM, EDAX, and AFM. The dry sliding wear results reveal that the wear resistance increases with increase in the percentage of graphite (Gr). The corrosion characteristics of the Co-Gr nanocomposites are examined using immersion and electrochemical methods. The electrochemical polarization results reveal the increase in corrosion resistant of the Co-25Gr nanocomposites (E corr = −0.416 V vs Ag/AgCl) to more positive side than pure Co (−0.443 V). Electrochemical impedance spectroscopy analysis results also confirmed Co-25Gr nanocomposite has higher resistance value (100 Ω). The results of the weight loss method also authenticate increase in corrosion resistance of Co-25Gr nanocomposite.

“…The addition of two reinforcements with varying weight percentages (wt.%) forms hybrid composites [ 13 , 14 , 15 ]. The hybrid magnesium composites are a new class of metal matrix composites widely used in automotive, marine, aerospace, and structural applications due to their low density, good mechanical properties, better corrosion and wear resistance, and low thermal expansion coefficient compared to conventional metals and alloys [ 16 , 17 ]. Microstructure and morphological changes in carbon nanotube films deposited on different substrates (mica, quartz, and TGX grating) by FESEM and atomic force microscopy was reported previously [ 18 , 19 ].…”

Magnesium matrix composites are extensively used in automotive and structural applications due to their low density, high strength, and wear-resistant properties. To reach the scope of industry needs, research is carried out regarding enhancing the mechanical and tribological behavior of the magnesium composites by reinforcing the nano-sized reinforcements. In the present work, research has been carried out to enhance the properties of the magnesium AZ91D hybrid composite by reinforcing carbon fibers (CFs) and multi-walled carbon nanotubes (MWCNTs) with varying weight percentages (AZ91D + 0.5% CF’s + 0.5% MWCNT and AZ91D + 0.75% CF’s + 0.75% MWCNT, respectively). The experimental tests were carried out to evaluate the mechanical and tribological behavior of the composites. The test results showed that the addition of CF and MWCNT reinforcements improved the hybrid Mg composite’s hardness, tensile strength, and impact strength compared to the base Mg matrix. The AZ91D + 0.75% CF’s + 0.75% MWCNT hybrid composite showed a 19%, 35%, and 66% increased hardness, tensile strength, and impact strength, respectively, compared to the base Mg AZ91D. The wear test results also showed the improved wear resistance of the Mg composite compared to the base matrix. The enhanced wear resistance of the composite is due to the addition of hard MWCNT and CF reinforcements. The wear rate of the AZ91D + 0.75%CF’s + 0.75% MWCNT composite for a load of 30 N at a sliding distance of 1500 m is lower as compared to the base matrix. The SEM micrographs of the worn surfaces revealed the existence of abrasive wear. The improved mechanical and tribological behavior of the magnesium composite is also due to the homogeneous distribution of the hard reinforcement particles along the grain boundaries.
