The present study focuses on the current development in the area of magnesium (Mg) based self-lubricating metal matrix composites (MMCs). Mg alloys and its composites are gaining importance in the field of aerospace, automobile, and medical industries due to their properties like light in weight, strength to weight ratio, stiffness, castability, and machinability. This study has imparted lights on the dry sliding wear behaviour of various Mg-based composites and hybrid composites fabricated with addition of different solid lubricants reinforcement’s particles such as Graphite (Gr), Boron Carbide (B4 C), Carbon Nanotubes (CNTs), Molybdenum Disulfide (MoS2 ), Tungsten Disulfide (WS2 ), Aluminium Oxide (Al2 O3 ), and Graphene Nanoplatelets (GNPs). Apart from this, their physical and mechanical properties are also discussed. It was found that addition of solid lubricants in Mg and its alloys leads to improved tribological properties due to formation of lubricative protective layer between sliding counter parts.
