“…Heavy plastic deformation and shear strains in the worn surface give rise to dislocation cells and elongated subgrains, as seen in i.e; Fig. 2, which is consistent with Heilmann et al (1983), Rigney et al (1981), Chen (1986), Chen and Rigney (1986) and Kuo and Rigney (1992). A is an example of A3004 alloys after 10.8km slid against M2 at 140N.…”

“…Generally, this process occurs during hot deformation of metals; however, several authors discussed it also in the SZ during sliding wear. Bill and Wisander [27] and Dautzenberg [28] reported on this phenomenon in copper, and Kuo and Rigney in aluminum [29]. They observed the grains free of dislocations in microstructure of their samples using TEM.…”

The annealing behavior of the subsurface zone (SZ) in pure bismuth induced by dry sliding was studied using the positron lifetime measurement. This measurement allows us to detect the SZ and its recovery, and recrystallization processes. The comparative measurements of the sample exposed to compression revealed the thermal stability of the SZ. The compressed sample rebuilt its structure due to the recovery and recrystallization processes at the temperature of 60°C, whereas the sample exposed to dry sliding does it at higher temperature of 260°C, which is close to the melting point. The isothermal annealing at the temperature of 100°C confirmed these results. The defect depth profile induced by dry sliding evolves with the annealing temperature in such a way that the concentration of defects at the worn surface gradually decreases, but at the depth between 50 and 170 lm, the generation of new defects takes place at the temperature of 75, 100 and even at 175°C. At the temperature of 175°C, the defects still are extended up to the depth of about 60 lm from the worn surface. The results were qualitatively confirmed by the measurements of the Vickers microhardness depth profile. Similar annealing behavior of the SZ was observed in pure magnesium.

“…However, one of the major drawbacks of these materials is their low wear resistance. This limitation is due to the fact that Al alloys undergo extensive plastic deformation and material removal under sliding wear conditions [3][4][5][6][7]. Furthermore, protective layers are not formed on the wear surface of these alloys under severe conditions, and direct metal-to-metal contact occurs between the sliding surfaces.…”

Improvement in surface properties and retainment of bulk properties are essential requirements for the design of components for wear resistance applications. This paper summarizes various features of Al/SiC/Gr hybrid composites that can be employed in different tribological applications. The study has revealed that the processing route plays a significant role in obtaining a homogeneous structure of these composites. In powder metallurgy, the selection of sizes of the matrix and reinforcement powders is crucial, whereas the wettability between the reinforcement particles and molten alloy is a major challenge in liquid metallurgy. The incorporation of SiC particles increases the mechanical strength and wear performance of Al composites. However, ejection of these particles can reduce the wear performance of Al composites under severe conditions. The addition of Gr particles helps in the formation of a thick and extensive tribolayer on the wear surface. This layer reduces direct contact between the rubbing surfaces, thereby decreasing the wear rate under certain conditions. Morphological analysis of worn surfaces has confirmed that the hybrid composites exhibit superior wear properties than the pure Al alloy and the ceramic-reinforced composite. However, increase in the Gr content beyond a limiting value can deteriorate the tribological properties of these composites. Therefore, true optimization of a tribosystem (of the hybrid composite and counterface) can be achieved by selecting appropriate reinforcement contents.
