“…MoS 2 will oxidize rapidly in 420~430 • C, and when the temperature is more than 800 • C, MoS 2 may decompose, and the friction coefficient of molybdenum metal is very large so the lubrication performance is greatly reduced. So, the analysis demonstrated that temperature is also an important factor affecting superlubricity [155][156][157][158][159][160][161][162]. There are also super-lubricant materials that need to be in special gases to have good superlubricity, such as MoS 2 , which has good lubricity in dry nitrogen, but poor lubricity in dry oxygen and humid air.…”

Friction and the wear caused by friction will not only lead to energy dissipation, but will also cause damage to the function of mechanical parts, affecting the precision and lifespan of mechanical devices. Superlubricity as an ideal state of zero friction has become a hot research topic in recent years. There have been many reviews on the concept, origin, and research progress of superlubricity, but, among them, there are more presentations on the research status of solid superlubricity and liquid superlubricity; however, the theoretical summarization of solid–liquid combined superlubricity and high-temperature superlubricity is still imperfect and lacks a systematic and comprehensive review. The mechanism of superlubricity is not explicitly presented in many reviews, which are clearly summarized in this paper. This paper introduces superlubricity from friction, and then introduces the origin of superlubricity, and presents the research progress on superlubricityby separating it into in four categories: liquid superlubricity, solid superlubricity, solid–liquid combined superlubricity, and high-temperature superlubricity. By analyzing the superlubricity system, the mechanism of realizing various types of superlubricity, such as incommensurability, hydration, and oxidation, is summarized. Based on the research progress of superlubricity, the development prospects, opportunities, and challenges of superlubricity in the future are discussed.

The biggest bottleneck restricting the application of two-dimensional (2D) g-C 3 N 4 material in water lubrication is the large-scale acquisition of g-C 3 N 4 nanosheets with satisfactory water dispersibility. In this work, a gel-like g-C 3 N 4 nanosheet hybrid with g-C 3 N 4 nanosheet cores and organic shells was constructed from the bulk g-C 3 N 4 by three procedures of Hummer's exfoliation, sulfonation, and acid−base neutralization. The hybrid in water exhibited nice water dispersibility and superior tribological performance. Adding 8 wt % of g-C 3 N 4 nanosheet hybrid made the friction coefficient and wear volume of water reduce by 73.7 and 72.3%, respectively. Moreover, its load-carrying capacity under high load and durability under a long-term test were also impressive. The worn surface analyses reflected that a thick protective lubrication film (>150 nm) was distinctly formed on the surface lubricated by the hybrid aqueous dispersion. This film was actually a tribofilm composed of amorphous tribochemical reaction products (Fe x O y , Fe x S y , and Fe x (SO 4 ) y ) embedded with Fe x O y and g-C 3 N 4 nanocrystals, which not only remarkably reduced the friction and wear but also effectively restrained the oxidation and corrosion of the friction pair. Given the possibility of large-scale construction and the prominent tribological performance, the g-C 3 N 4 nanosheet hybrid is a promising candidate to be developed as a particularly promising water-based additive.

The unique tribological characteristics of black phosphorus quantum dots (BPQDs) have recently attracted much attention. However, the long-term stable lubrication of BPQDs and prevention of degradation in ultrapure water remain huge challenges. Herein, BPQDs@silica (BPQDs@SiO2) core–shell materials were designed and synthesized. The BPQDs are uniformly distributed in the SiO2 shell. The as-prepared BPQDs@SiO2 as the water-based lubrication additive has remarkable lubricity, wettability, and stability. In particular, compared with the average coefficient of friction (COF) and wear rate of ultrapure water, those of BPQDs@SiO2, being a water-based lubrication additive, could be reduced by 45.7 and 83.0% at 10 N and 150 r/min, respectively. The lubrication mechanisms of BPQDs@SiO2 as a water-based lubrication additive were proposed based on the friction test and wear surface analysis. The excellent lubricity performances of BPQDs@SiO2 are owed to the polishing of the SiO2 shell, the extreme pressure property of the BPQD core, and the tribo-chemical reaction film. This investigation established a simple, convenient, and feasible method for using the BPQDs@SiO2 materials as a water-based lubrication additive. It is expected that BPQDs with a core-shell nanostructure will open up new ideas for the development of excellent lubricating nanomaterials.
