“…The EDX (Figure 8a) and elemental mapping (Figure 8b) results show the presence of oxygen and carbon elements that dictate the presence of oxides and carbides over the composite surfaces. The modified elemental composition helps to increase the hardness of the prepared surface composite [24]. However, according to the Pascal Law, it is known that the wear resistance property is directly proportional to the hardness value of that sample [25].…”

In the present study, the surface composite Al359/Si3N4/Eggshell is prepared by friction stir processing (FSP). The effect of reinforced particle volume fraction on the microstructural and tribological properties of the Al359/Si3N4/Eggshell surface composites was investigated and compared with the friction stir processed (FSPed) Al359 alloy. The microstructural properties were further investigated by light microscopy, FESEM, and EDS mapping. The tribological properties of the developed composite and FSPed Al359 were investigated using a reciprocating ball-on-plate universal tribometer. The microstructural results showed that defect-free composite surfaces are produced due to improved physical properties, severe plastic deformation, and better grain refinement. Moreover, the mean value of the friction coefficient (µ) for the developed composite and FSPed alloy are 0.36 µ and 0.47 µ, respectively. The obtained results indicated that Si3N4/Eggshell is a promising reinforced particle for improving microstructural and tribological performance in journal bearing, rotors, and machinery applications.

“…The evolution of the intermetallic components and the microstructure were investigated in the FSW technique, which has a strong effect on the strength of the joint boundary of dissimilar titanium alloys and that of dissimilar aluminum materials [1,2]. The joining of aluminum to copper has been attractive in electric or battery parts, and it has been investigated [3][4][5]. Further, the addition of Ni at the interface and the coating of the titanium layer on the copper side increased the strength [6,7].…”

Joining of pure copper C1100 and aluminum alloy A6061-T6 plates of 5 mm thickness was investigated. The method was developed by one of the authors, in which the newly created surfaces of a pair of plates obtained by high-speed shear were immediately in contact with a sliding motion with a small overlap length. The total processing time was just about a few milliseconds. To create the new surface, high-speed shaving was also tested. The joining was not possible for the full thickness of the plates. A sharp notch was observed at the joint boundary due to a large shear droop in the copper. Shaving decreased the shear droop, and the joint length through the plate thickness became longer. The joining performance was evaluated by a uniaxial tensile test. The joint efficiency reached 100% using the specimen cut out from the really joined boundary. The affected zone of joining was confirmed by the hardness distribution near the boundary. It was about 30% of the thickness of the plate, which was much smaller than that in welding by heat, and no softened zone was found in both materials.
