In this article, the effect of infusion of silver nanoparticles into the base oil lubricants was investigated. In this study, Jatropha and Pongamia oils were used as base oils and silver nanoparticles infused at 0.25%, 0.5%, and 0.75% weight-percentage of the base oils to create nano-based bio-lubricants. The influence of silver nanoparticles on the Tribological and Thermophysical properties of the base oils was analyzed through various test procedures. The Pin-on-disc tribometer test was done to measure friction and wear at various loads. Pin made of Aluminum metal matrix composite fabricated by stir casting method was used and the results revealed that the inclusion of silver nanoparticles significantly improved the friction and wear properties of the base oils. Pin-worn surface morphology was analyzed using a field emission scanning electron microscope and X-ray diffraction. Thermal conductivity and kinematic viscosity of nano-based bio-lubricants were evaluated as per ASTM standards and the results showed that both the thermal conductivity and kinematic viscosity increased with the infusion of silver nanoparticles.

“…Researchers have reported the second category of PRAMCs, reinforced with pure metallic elements (Ni, Ti, Cu, and Fe, etc.) to obtain ductility with high strength [21][22][23][24]. However, in these composites, interfacial reactions result in the formation of solid solutions or brittle aluminides.…”

In this study, Al matrix composites (AMCs) reinforced with Al/Cu core-shell particles were synthesized by hot pressing. The Al/Cu particulate reinforcements were pre-synthesized by galvanic replacement. The effect of the volume fraction of reinforcement on the microstructure and mechanical behavior of the composites was investigated by scanning electron microscopy (SEM), X-ray diffraction (XRD), micro-hardness and compression tests. The strength of the composite becomes 2.25 times the matrix by using 20 vol.% core-shell reinforcements containing only 6 vol.% Cu. Further, with increasing volume fraction of Al/Cu reinforcement, the degree of in-situ transformation of Cu into intermetallic also increases. Consequently, a specially tailored microstructure can be obtained by controlling the volume fraction of the reinforcement and its interfacial reaction with the matrix, which can improve the mechanical strength of composites without considerably compromising on fracture strain. The findings of this work provide stronger implications for the industry to fabricate viable engineering structures.

SiCp/A390 composite was fabricated by powder metallurgy method and hot extrusion process. The interfacial microstructure of SiCp/A390 composites after heat treatment was characterized by HRTEM. The results show that the interface between SiC and Al matrix has an orientation relationship of [4510] SiC //[011] Al , (1010) SiC //(111) Al and forming a semi-coherent interface. The crystallographic orientation relationship between SiC and Si in the SiCp/A390 composites is [010] SiC //[001] Si , (004) SiC //(220) Si. The interplanar spacing of Al matrix on lattice plane (111) is close to the twice interplanar spacing of the Si phase on lattice plane (400). They keep a semi-coherent crystal plane, with an orientation relationship of [011] Al //[001] Si , (111) Al //(400) Si .
