“…[60] This method applies ultrasonication, mechanical shearing, and electrochemical processing of bulk crystals that are separated into single-or multi-layer flakes, which are dispersed in a carrier solution, such as ethanol [61] or water and spray-coated, [61] ink-jet printed, [62] or burnished onto the substrate. [63] An overview of the deposition methods for the different 2D materials with a comparison of the deposition temperature, the coating thickness, the scalability, and the surface geometry is provided in Table 1.…”

“…In many cases, the use of 2D materials as solid lubricants was especially beneficial for aerospace [110] and high-temperature applications. [63,111,112] Meanwhile, the incorporation of 2D materials as additives found its niche in the automotive industry [113] and for marine applications. [114] We expect that the potential industrial uses for 2D nanomaterials in sliding bearings will continue to increase in the near future when combined with a wide range of materials, such as soft metals (e.g., bronze), polymers (e.g., PA, POM, PTFE), and composites, even if they are not yet represented in published research and are not applied in sliding bearings already in industrial usage.…”

prominent members being molybdenum disulfide (MoS 2 ) and tungsten disulfide (WS 2 ). [2] In addition to graphene-and TMD-based nanomaterials, new 2D nanomaterials [3] such as silicenes, [4] hexagonal boron nitride (h-BN), [5] black phosphorous (BP), [6,7] halide structures, [8] metal-organic framework nanosheets, [9] and MXenes [10,11] are currently optimized regarding their synthesis methods and expectable yield. The coupling of excellent electrical and thermal conductivity with great mechanical properties, high surface-to-volume ratios, and the existence of surface terminations, which enable their chemical functionalization, has made these 2D nanomaterials promising candidates to be used in different applications such as energy storage devices and supercapacitors, [12] (photo)-catalysis, [13] water purification, [14] and tribological systems. [15][16][17][18] In the tribological context, 2D layered structures showed their great potential in improving friction and wear of various substrate materials under dry and lubricated conditions. With respect to the lubricated conditions, 2D materials are typically used as lubricant additives in base oils with the overall purpose to fulfill different functions in the contact area. During sliding, nanomaterials may act both as shearing films and nano-roller bearings, thus potentially changing the friction mode from sliding to rolling friction and regulating the resulting lubricant flow, thus reducing frictional losses. [19] Irrespective of the prevalence of dry or lubricated conditions, 2D materials may be capable of initiating tribo-chemical reactions in the contact area Recent advances in 2D nanomaterials, such as graphene, transition metal dichalcogenides, boron nitride, MXenes, allow not only to discover several new nanoscale phenomena but also to address the scientific and industrial challenges associated with the design of systems with desired physical properties. One of the great challenges for mechanical systems is associated with addressing friction and wear problems in machine elements. In this review, the beneficial properties of layered 2D materials that enable the control of their tribological behavior and make them excellent candidates for efficient friction and wear reduction in dry-running and boundary lubricated machine components are summarized. The recent studies highlighting the successful implementation of 2D structures when used as solid lubricant coatings or reinforcement phases in composites for various machine components including sliding and rolling bearings, gears, and seals are overviewed. The examples presented in the studies demonstrate the great potential for 2D materials to address the energy-saving needs by friction and wear reduction.

“…In efforts to solve the tribological challenges related to high temperature applications, focus was rather directed toward ternary oxides and carbides that are in general incapable of near-zero friction sliding (Gao et al, 2015;Aouadi et al, 2020). A possible solution is to enable adaptive behavior of materials under changes in the testing conditions which was successfully shown in case of graphite-MoS 2 chameleon coatings (Shirani et al, 2020). The COF values were significantly reduced (down to 0.02 values) when testing the materials at elevated temperature conditions.…”

“…Though Sb 2 O 3 is rarely used as an anti-wear or friction reduction additive, it is beneficial as a dopant to play a synergistic role with MoS 2 in the solid lubricant coating (Zabinski et al, 1993(Zabinski et al, , 1995Hu et al, 2006). It was previously reported that the MoS 2 -Sb 2 O 3 -C film can change its surface with the environment changes to maintain good tribological performance by adapting to the testing conditions (Shirani et al, 2020). In another study it was found the COF of the sputter-deposited amorphous MoS 2 -Sb 2 O 3 -Au films decreases during sliding in a dry nitrogen environment as a result of MoS 2 changing from amorphous to crystalline phase during this process (Scharf et al, 2010).…”

Here, we report the high-temperature superlubricity phenomenon accomplished in coatings produced by burnishing powders of antimony trioxide (Sb2O3) and magnesium silicate hydroxide coated with carbon (MSH/C) onto the nickel superalloy substrate. The tribological analysis performed in an open-air experimental setup revealed that with the increase of testing temperature, the coefficient of friction (COF) of the coating gradually decreases, finally reaching the superlubricity regime (the COF of 0.008) at 300°C. The analysis of worn surfaces using in-situ Raman spectroscopy suggested the synergistic effect of the inner Sb2O3 adhesion layer and the top MSH/C layer, which do not only isolate the substrate from the direct exposure to sliding but also protect it from oxidation. The cross-sectional transmission electron microscopy (TEM) and X-ray photoelectron spectroscopy (XPS) results indicated the tribochemically-activated formation of an amorphous carbon layer on the surface of the coating during sliding. Formation of the film enables the high-temperature macroscale superlubricity behavior of the material system.

“…Among the effective parameters, the type of applied electrical regime can affect the porosity and cracking networks of the coating as well as its chemical composition. Therefore, by selecting the appropriate electrical regime, and controlling the porosity, cracking and the type of formed phases in the coating, better mechanical properties and corrosion resistance can be provided for PEO coatings [12,[15][16][17].…”
