Surface texturing and solid lubricants have demonstrated the ability to substantially reduce friction and wear under dry conditions. In recent decades, these two technologies have been combined to leverage the advantages of both for superior tribological performance. This review article first summarizes the state-of-the-art regarding surface texturing and solid lubricants, including soft metals, polytetrafluoroethylene, diamond-like carbon and 2D layered materials. Then, the synergy between surface textures and solid lubricants is discussed, with particular emphasis on the underlying mechanisms. Finally, gaps in the existing understanding of these synergies are identified and opportunities for future research are suggested.

“…Two-dimensional (2D) layered nanomaterials, such as transition metal dichalcogenides (TMDs) [2,3], carbon nitride (C 3 N 4 ) [4], graphene [5,6], zirconium phosphate [7], palygorskite nanoplatelets [8], hexagonal boron nitride (hBN) [9], and MXene (Ti 3 C 2 ) [10], have demonstrated high potential in the field of water-based lubricant additives [11][12][13]. Using these nanomaterials as additives can effectively enhance friction reduction and anti-wear performance in lubricants; however, they also have several shortcomings, including poor dispersion stability, non-uniform particle sizes, and poor embedding stability between the rubbing surfaces [14,15].…”

Black phosphorus quantum dots: A new-type of water-based high-efficiency lubricant additive

et al. 2020

Black phosphorus quantum dots (BPQDs), obtained via a typical solution-based top-down method, were used as water-based lubricant additives. BPQDs exhibited remarkable friction reduction and anti-wear properties even at the ultra-low concentration of 0.005 wt%, which reduced the friction coefficient and wear volume of the base liquid by 32.3% and 56.4%, respectively. In addition, the load-supporting capacity of the base liquid increased from 120 N to over 300 N. BPQDs-based additives exhibited a relatively long lifetime at a relatively high load of 80 N. The performance of BPQDs considerably exceeded that of the BP; this may be attributed to their small and uniform particle size, good dispersion stability in water, and high reactivity at the frictional surfaces. The results of the surface wear resistance analysis demonstrated that a robust tribochemical film with a thickness of approximately 90 nm was formed on the rubbing surface lubricated with 0.005 wt% of BPQDs dispersion. Moreover, the film served as a direct evidence of the excellent tribological performance of BPQDs.

“…2d). These improvements in wear behavior were attributed to the formed Ti 3 C 2 T x -tribolayer at the contact point which reduced the required shear force for motion at the interface [49]. The reduced shear force required for contact motion in this tribolayer can be attributed to the low interlayer sliding friction between terminated MXene sheets [50].…”

“…c MXenes can also be included into lower melting point metals in their molten phase, where sonication assists the homogenous dispersion of MXene flakes into the molten metal [48]. d Ti 3 C 2 T x MXene flakes in a Cu matrix have shown a reduction of the coefficient of friction of two times over a pure Cu matrix [49] high negative surface charge of MXene sheets due to its surface groups [25,35] provides significant potential of MXenes toward solution-based mixing methods, such as electrostatic self-assembly [44]. In addition, MXenes' status as the stiffest solution-processable 2D nanomaterial makes MXene a great candidate 2D nanomaterial for additive manufacturing and powder metallurgy mixing processes in metal matrix composites for structural applications.…”

2D transition metal carbides (MXenes) in metal and ceramic matrix composites

2021

View full text Add to dashboard Cite

Two-dimensional transition metal carbides, nitrides, and carbonitrides (known as MXenes) have evolved as competitive materials and fillers for developing composites and hybrids for applications ranging from catalysis, energy storage, selective ion filtration, electromagnetic wave attenuation, and electronic/piezoelectric behavior. MXenes’ incorporation into metal matrix and ceramic matrix composites is a growing field with significant potential due to their impressive mechanical, electrical, and chemical behavior. With about 50 synthesized MXene compositions, the degree of control over their composition and structure paired with their high-temperature stability is unique in the field of 2D materials. As a result, MXenes offer a new avenue for application driven design of functional and structural composites with tailorable mechanical, electrical, and thermochemical properties. In this article, we review recent developments for use of MXenes in metal and ceramic composites and provide an outlook for future research in this field.
