“…Specifically, the friction force could reduce by about 50% at the degraded area of the BP nanosheets due to the phosphorus oxides formed after degradation. Although to a lesser extent than graphene and MoS 2 , other 2D materials, such as boron nitride, h-BN [147,148], Mg/Al layered double hydroxides (LDHs) [149], TiO 2 /Ti 3 C 2 T x hybrid nanocomposites [150], have also been investigated as liquid lubricant additives.…”

The reach of tribology has expanded in diverse fields and tribology related research activities have seen immense growth during the last decade. This review takes stock of the recent advances in research pertaining to different aspects of tribology within the last 2 to 3 years. Different aspects of tribology that have been reviewed including lubrication, wear and surface engineering, biotribology, high temperature tribology, and computational tribology. This review attempts to highlight recent research and also presents future outlook pertaining to these aspects. It may however be noted that there are limitations of this review. One of the most important of these is that tribology being a highly multidisciplinary field, the research results are widely spread across various disciplines and there can be omissions because of this. Secondly, the topics dealt with in the field of tribology include only some of the salient topics (such as lubrication, wear, surface engineering, biotribology, high temperature tribology, and computational tribology) but there are many more aspects of tribology that have not been covered in this review. Despite these limitations it is hoped that such a review will bring the most recent salient research in focus and will be beneficial for the growing community of tribology researchers.

“…As the base oil containing 0.075 wt% CPBA‐BNNSs is applied, the average WSD is decreased to 0.36 mm and there is the lowest wear on the surface of friction. Since, the weakly stacked lamellar structure of CPBA‐BNNSs provides low shearing strength, which can minimize the direct contact of the sliding surfaces, thereby reducing wear and friction . It is worth mentioning that the average WSD and the MWV of 150N base oil with 0.075 wt% CPBA‐BNNSs are reduced by 42.9% and 88.4% than those of the base oil.…”

Hexagonal boron nitride nanosheets (h‐BNNSs) are obtained by a chemical exfoliation method from bulk h‐BN powders. The surface of h‐BNNSs is functionalized with 3‐aminopropyltriethoxysilane (APTS). Further, the amino functional groups on the surface of APTS‐modified h‐BNNSs (APTS‐BNNSs) are reacted with 4‐carboxyphenylboronic acid (CPBA) to obtain the covalently linked CPBA‐BNNSs. The morphology and structure of h‐BNNSs, APTS‐BNNSs, and CPBA‐BNNSs are comprehensively discussed. Of all the above four additives, the CPBA‐BNNSs can most outstandingly improve friction‐reducing and antiwear capacities of 150N base oil. The CPBA‐BNNSs possess excellent dispersion stability in base oil due to the phenylboronic acid groups on the surface of h‐BNNSs. Only 0.075 wt% CPBA‐BNNSs is added into the base oil, the coefficient of friction is decreased by 32.3%, and the wear scar diameter and mean wear volume of the rubbing surface are reduced by 42.9% and 88.4%. The analysis of the worn scar surface demonstrates that CPBA‐BNNSs can form a protective tribofilm containing boron and nitrogen elements on the rubbing surfaces, thereby decreasing the friction and protecting the surfaces from wear. Thus, the CPBA‐BNNSs may be recommended as a potential lubricant additive in practical applications.

“…The water‐glycol with 0.05 wt% HO‐BNNS shows the lowest WSD value, approximately 60% lower than a water‐glycol base solution. The excellent dispersion of HO‐BNNS and the weak layered structure with lower shear strength can effectively reduce the direct contact of the sliding surface, thus reducing wear and friction . The MWV is calculated by the Equation

h = r - \sqrt{r^{2} - \frac{d^{2}}{4}}

W V = \frac{π h}{6} (\frac{3 d^{2}}{4} + h^{2})

where d is wear scar diameter (WSD) and r is the radius of the steel ball.…”

Hexagonal Boron nitride (BN) can be used as a lubricant additive, which can dramatically reduce friction energy. However, due to the accumulation of BN in the water-based lubricants and the difficulty of entering the friction contact area, the tribological performance of BN becomes worse. To address this issue, the atomically thin hydroxylated boron nitride nanosheets (HO-BNNS) were successfully prepared. The thickness of HO-BNNS is only 0.6-0.8 nm. Meanwhile, the HO-BNNS has excellent dispersion stability in water-based lubricants because of the hydroxyl group on the surface of HO-BNNS. The as-prepared HO-BNNS exhibits unique friction properties as a water-based dispersible lubricant additive. Additionally, the average wear scar diameter, average friction coefficient, and mean wear volume of HO-BNNS/water-based (0.05 wt%) drop by about 64.7%, 60%, and 95.73%. Finally, the introduction of HO-BNNS can well control the temperature of water-based lubricant.
