“…The results indicate that wear of hybrid composites initially decreases with increasing Gr contents up to 5 wt.% and then increases for 10 wt.% Gr contents (for fixed percentage of SiC) in the hybrid composites. Overall, the presence of Gr particles improves the tribological properties of Al-based composites [30,[79][80][81]. Notably, the wear rate of Al composites increases with increased load because of adhesive wear.…”

“…Figures 11(a) and 11(b) show the micrographs of Al/5%SiC/10%Gr composites; indistinct grooves and fine scratches exist on the worn surface of the composite. The wear mechanisms are characterized by the formation of grooves via plowing of hard asperities of the counterface and hardened wear debris, and temperature rise is one of the most significant factors [79].…”

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.

In this study, corrosion and electric conductivity of aluminum hybrid composites (in situ TiAl3 and ex situ B4C) produced by powder metallurgy are investigated. Hybrid (in situ and ex situ) aluminum composite powders are produced by adding different amounts of titanium and B4C into AA7075 alloy powders. After the hybrid composite powders are cold pressed (600 MPa), they are sintered in atmosphere controlled furnace at 580• C for 4 h. As a result of this study, it was observed that increase of B4C%(Ti constant) decreases density and increase of Ti%(B4C constant) increases the density of composites. It was determined that corrosion resistances (Rp) of hybrid composites decreased due to interface surfaces formed between the reinforcement phase and the matrix.

In this paper, wear characteristics of hybrid composite of Al6061 was studied. Hybrid composite was reinforced with silicon carbide (SiC) with varying (3%, 6%, 9%) weight % and keeping the alumina (Al2O3) with constant (10) weight percentage. Stir casting method was used to fabricate the composite. T6 heat treatment was applied on the sample before doing the wear test. Pin on disc apparatus was used to perform the wear test. SEM was performed to do the microstructural analysis. It was found that hardness and density of samples increased as the percentage of SiC increases. L9 orthogonal array was applied to check the interaction between different wear parameters using the Taguchi technique.
