Abstract
Abstract Chicken eggshell (Es) waste is an industrial byproduct, and its disposal constitutes a severe environmental risk. Eggshell is a new engineering reinforcement retaining excellent properties such as low density, renewable, eco-friendly, and high thermal stability. The current research aims to study the effects of eggshell particles addition on microstructures, mechanical and tribological properties of aluminium/eggshell green metal matrix composites (MMCs). In the present work Al–Es metal matrix composite is produced by powder metallurgy processes. SEM with EDX and XRD were used to examine the microstructures and the compounds that arise during the sintering process of the produced composites. Six tests were conducted on the produced samples including; dry wear test, micro Vickers hardness, and ultimate compressive strength. The results showed that the addition of 3 wt. % of eggshell improved wear resistance (65%), compressive strength (40%) and hardness (15%). At 6 and 9 wt. % of eggshell, negative results appeared.
Highlights
Metal matrix composites (MMCs) are engineering materials that rapidly replace monolithic materials due to Usually, metal matrix is combined with ceramic particles to incorporate metal matrix properties with ceramic properties

Ceramic particles that were used as a reinforcement to fabricate metal matrix composites (MMCs) include alumina (Al2O3), silicon carbide (SiC), boron carbide (B4C), graphite (Gr), carbon nanotubes (CNTs), carbon (C), silicon oxide (SiO2), fly ash (FA), eggshells (Es) and others [11–15]
Summary
Metal matrix composites (MMCs) are engineering materials that rapidly replace monolithic materials due to Usually, metal matrix is combined with ceramic particles to incorporate metal matrix properties with ceramic properties. This combination leads to higher strength and lower wear rate [7, 8]. Ceramic materials can be found in different forms such as long fibers, short fibers (whisker), particles and filaments. Particulate composites have an advantage over other forms of composites because they have isotropic properties [9, 10]. Ceramic particles that were used as a reinforcement to fabricate MMCs include alumina (Al2O3), silicon carbide (SiC), boron carbide (B4C), graphite (Gr), carbon nanotubes (CNTs), carbon (C), silicon oxide (SiO2), fly ash (FA), eggshells (Es) and others [11–15]
