TLDR
In this article, the friction and wear behavior of graphene-lubricated 440C steel test pairs in dry nitrogen under different loads was investigated and it was shown that a few-layer graphene is able to drastically reduce the wear and the coefficient of friction (COF) of steel during the initial sliding regime and under low load conditions.About:

Approaches for Achieving Superlubricity in Two-Dimensional Materials.
TL;DR: This review outlines basic mechanisms for frictional energy dissipation during sliding of two surfaces against each other, and the procedures for manipulating friction and wear by introducing 2D materials at the tribological interface, and highlights recent progress in implementing2D materials for friction reduction to near-zero values-superlubricity-across scales from nano- up to macroscale contacts.

A review of recent developments of friction modifiers for liquid lubricants (2007–present)
TL;DR: There are three types of friction modifiers for liquid lubricants: organomolybdenum compounds, organic friction modifiers, as well as nanoparticles as mentioned in this paper, and the problems and some suggestions for the future directions of research on friction modifiers are proposed.

The rise of graphene
TL;DR: Owing to its unusual electronic spectrum, graphene has led to the emergence of a new paradigm of 'relativistic' condensed-matter physics, where quantum relativistic phenomena can now be mimicked and tested in table-top experiments.
