Abstract

Recently, because friction has a detrimental effect on longevity, effectiveness, and environmental friendliness, it is becoming more and more crucial to reduce friction and wear-related mechanical failures in moving mechanical systems. As a result, researchers are still looking for new materials, coatings, and lubricants (solid and liquid) that help reduce wear and friction. One of the most significant scientific discoveries of this time has been the family of materials called graphene. Researchers have looked into the graphene family of compounds, which provide promise as physicochemically unique additions for various lubrication systems. This review summarizes the studies conducted on the tribological characterization of materials of the graphene group, such as functionalized graphene, and composites of graphene nanoparticle-decorated graphene and other materials. In addition, graphene-family compounds as lubricating additives, open issues, and promising future directions are covered in the article.
