“…Kalkanli and Yilmaz (2008) prepared Al7075/SiC composites by squeeze casting method and concluded 10 wt.% SiC reinforced composites showed the best hardness, tensile strength and flexural strength in both as cast and heat treated conditions. Flores-Campos et al (2010) fabricated the Al7075 composites with carbon-coated silver nanoparticles and concluded that Vickers micro hardness (HVN) values were higher at higher Ag-CNP contents. Baradeswaran and Elaya Perumal (2014) developed the Al7075 hybrid metal matrix composite through stir casting method.…”

This paper investigates the mechanical properties and corrosion behavior of Metal Matrix Composites prepared using Al7075 alloy as a matrix, Silicon Carbide and Titanium Carbide as reinforcement particles. Two step stir casting process was used to fabricate the composites by varying volume fractions of Silicon Carbide and Titanium Carbide (0 to 15 vol. %). Microstructural analysis, mechanical and corrosion behavior were used to evaluate the performance of the composites. Uniform distribution of reinforcement particle was observed through optical photomicrographs. Vickers micro hardness tests were performed and the hardness values were increased with an increase in reinforcement from 0 to 15 vol. %. The tensile strength of the 10 vol. % of aluminum hybrid matrix composite was better than that of the base alloy. In 3.5% NaCl solution, it was observed that the 15 vol. % of the aluminum hybrid matrix composite have higher corrosion resistance in comparison the base alloy.

“…The silver nanoparticles effect over in the particle size is due to (i) silver nanoparticles acts as a process control agent (PCA) [10], refining the particle size during the milling process, and (ii) that silver nanoparticles acts as a solid lubricant during the plastic deformation in the milling process [11], generating in this way, particles with smaller sizes, and reaching a steady state between the fracture and welding mechanisms of the particles at shorter milling times.

“…The milling times selected were 0, 5, 10 and 15 h. The total milling load was 10 g and the milling ball-to-powder weight ratio was set at 4 to 1, the SPEX vials and milling media were made of hard steel. To avoid oxidation during milling, all runs were done under argon atmosphere, 0.25 ml of methanol as a process control agent (PCA) was used in all experiments [11]. Milling products were cold compacted in steel die with 4 cm diameter.…”

Nanostructured composites of the aluminum 7075 alloy and carbon-coated silver nanoparticles were synthetized by the mechanical milling technique using a high-energy mill SPEX 8000M; the powders generated were compacted, sintered and hot-extruded to produce 1 cm-diameter bars. The composites were then subjected to a wear test using a pin-on-disc device to validate the hypothesis that second phase-ductile nanometric particles homogenously distributed throughout the metalmatrix improve the wear resistance of the material. It was found that silver nanoparticles prevent the wear of the material by acting as an obstacle to dislocations movement during the plastic deformation of the contact surface, as well as a solid lubricant when these are separated from the metal-matrix.
