The automotive and aviation industries are required lightweight materials to enhance working efficiency. Composites are developed as lightweight alternatives materials, blending materials such as aluminium, magnesium, titanium, steel, copper, and their alloys in various combinations. The present investigation to fabricate a Silver-Grey Magnesium (Mg-25%Si) alloy-based nanocomposite with silicon dioxide (SiO2) nano reinforcement at weight % of 0, 3.25, 6.5 and 9.75 utilizing two steps stir casting method. The nano reinforcements different wt. % are prepared by using agricultural waste prosopis juliflora. The microhardness, tensile, wear, and impact tests are performed on the Silver-Grey Magnesium nanocomposites (Mg-25%Si/SiO2) utilizing a computerized tensometer testing machine, a Vicker’s hardness tester, a pin-on-disc tribometer, and an Izod impact, respectively. The X-ray diffraction (XRD), Field Emission Scanning Electron Microscope (FESEM), and Energy-dispersive X-ray spectroscopy (EDAX) with elemental mapping microstructure were employed to scrutinize the tensile specimen fracture, EDAX, elemental mapping microstructure, wear, CoF, and worn surface characterization and impact strength analysis. The results of the Mg-25%Si/SiO2 nanocomposites shown an increase in SiO2 nano reinforcements that considerably increased microhardness, tensile strength, wear resistance, and impact strength when compared to the Silver-Grey Magnesium (Mg-25%Si) base alloy.

The XRD examination of the materials was performed utilizing a back loading preparation technique [32]. The materials were examined using a PANalytical Empyrean diffractometer equipped with a PIXcel detector, fixed slits, and Cu-Ka1 radiation with a Fe filter (= 1.540598 A).…”

Metal matrix composite (MCC) exhibits significantly better properties, like hardness, low density, high tensile strength, and good wear resistance compared to any alloy or other metals. In the present study, the effect of using different proportions (2, 4, 8 and 10 wt.%) of microscopic slide glass nanoparticles (MSGNPs) on the properties of Al-7075 alloy was investigated. The results of the experimental study of the metallurgical characterization and mechanical properties of aluminum MMC that formed by stir casting method were obtained. Stir casting is a process of introducing a reinforcing material into a molten metal by stirring action. Also, the results of the aluminum MMC were compared with those for the base alloy material. Optical microscopy, scanning electron microscope (SEM), energy dispersive spectroscopy (EDS), and X-ray diffraction study (XRD) were carried out to analyze the microstructure and the dispersion of the (MSGNPs) into the composite alloy specimens. Regarding the mechanical properties, the Rockwell hardness gradually increased when the addition of MSGNPs was raised from 0 to 10 wt.%. Additionally, there was a rise in the ultimate tensile strength, peaking at the incorporation rate of 4 wt.% MSGNPs and thereafter, this strength declined. Therefore, the addition of microscopic slide glass nanoparticles to the Al-7075 is virtuous to enhance the properties of this alloy for the engineering application.

“…Moreover, the implanted ions could contribute to further improvement in corrosion behavior. As a dopant ion, the implanted nitrogen ions (N + ) lead to improved corrosion behavior and mechanical properties [ 17 , 18 , 19 , 20 , 21 ]. Hence, we expected that the implantation of N + ions on the Nb layer would modify its structural properties and reinforce its corrosion resistance ability.…”

N+-Implantation on Nb Coating as Protective Layer for Metal Bipolar Plate in PEMFCs and Their Electrochemical Characteristics

Nitrogen ions were implanted into the coated Nb layer by plasma immersion ion implantation to improve resistance to corrosion of a metal bipolar plate. Due to nitrogen implantation, the corrosion behavior of the Nb layer was enhanced. The electron microscope observation reveals that the microstructure of the Nb layer became denser and had fewer defects with increasing implantation energy. As a result, the densified structure effectively prevented direct contact with the corrosive electrolyte. In addition, at a higher implantation rate (6.40 × 1017 N2/cm2), a thin amorphous layer was formed on the surface, and the implanted nitrogen ions reacted at neighboring Nb sites, resulting in the localized formation of nitrides. Such phase and structural changes contributed to further improve corrosion resistance. In particular, the implanted Nb layer at bias voltage of 10 kV exhibited a current density more than one order of magnitude smaller with a two times faster stabilization than the as-deposited Nb layer under the PEMFC operating conditions.
