Graphene: a new emerging lubricant ☆
TL;DR: A review of recent tribological studies based on graphene from the nano-scale to macro-scale, in particular, its use as a self-lubricating solid or as an additive for lubricating oils is provided in this paper.
Journal ArticleDOI
Macroscale superlubricity enabled by graphene nanoscroll formation

TL;DR: Simulations showed that sliding of the graphene patches around the tiny nanodiamond particles led to nanoscrolls with reduced contact area that slide easily against the amorphous diamondlike carbon surface, contributing to superlubricity at engineering scale.
Journal ArticleDOI
Few layer graphene to reduce wear and friction on sliding steel surfaces
TL;DR: In this article, solution-processed graphene layers were used to reduce friction and wear on sliding steel surfaces in air (relative humidity, 30%), and small amounts of graphene-containing ethanol solution decreased wear by almost 4 orders of magnitude and friction coefficients by a factor of 6.
Journal ArticleDOI
Synthesis and characterization of highly-conducting nitrogen-doped ultrananocrystalline diamond films

TL;DR: In this paper, trananocrystalline diamond (UNCD) films with up to 0.2% total nitrogen content were synthesized by a microwave plasma-enhanced chemical-vapor-deposition method using a CH4(1%)/Ar gas mixture and 1%−20% nitrogen gas added.
Journal ArticleDOI
Reduced wear and friction enabled by graphene layers on sliding steel surfaces in dry nitrogen
TL;DR: 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.
