Abstract

Development of novel lubricant materials to reduce the friction and wear for a diversified range of tribological applications is a subject of great interest. Over the last one decade, two-dimensional (2D) nanostructured layered materials have attracted immense interests for a wide range of applications including enhancement of tribological properties. The fascinating and favorable characteristics of 2D nanomaterials viz. excellent thermal conductivity to take away the heat from contact interfaces, exceptionally high mechanical strength to provide remarkable wear-resistivity, low shear strength to reduce the friction, and high surface area to facilitate their dispersion have made the 2D nanomaterials highly promising candidates for solid thin films and additives to liquid lubricants. The chapter discusses the tribological applications of graphene, MoS2, WS2, and h-BN as additives to automotive lubricants, greases, and metalworking fluids. The chemical functionalization and dispersion aspects of 2D nanostructured layered materials, tribo-performance using variable contact geometries, and analyses of worn surfaces etc. are presented to outlines the lubrication mechanism.
