“…[ 25 ] The better performance of these coatings can be achieved by including Mo‐containing compounds and further doping to match the lubricants used in rubbing surfaces by tuning the surface energy or to match the stiffness of the mechanical components. [ 26 ] Through Ti, [ 27 ] Cr, [ 28 ] Zr, [ 29 ] Ni, [ 30 ] Ti‐Si, [ 31 ] or Sb 2 O 3 [ 32 ] doping, MoS 2 coating hardness can be increased owing to a distortion of its crystal structure, which leads to improved wear resistance. Au doping of the MoS 2 coating has a different enhancement mechanism.…”

There has been tremendous interest in the development of different innovative wear‐resistant materials, which can help to reduce energy losses resulted from friction and wear by ≈40% over the next 10–15 years. This paper provides a comprehensive review of the recent progress on designs, properties, and applications of wear‐resistant materials, starting with an introduction of various advanced technologies for the fabrication of wear‐resistant materials and anti‐wear structures with their wear mechanisms. Typical strategies of surface engineering and matrix strengthening for the development of wear‐resistant materials are then analyzed, focusing on the development of coatings, surface texturing, surface hardening, architecture, and the exploration of matrix compositions, microstructures, and reinforcements. Afterward, the relationship between the wear resistance of a material and its intrinsic properties including hardness, stiffness, strength, and cyclic plasticity is discussed with underlying mechanisms, such as the lattice distortion effect, bonding strength effect, grain size effect, precipitation effect, grain boundary effect, dislocation or twinning effect. A wide range of fundamental applications, specifically in aerospace components, automobile parts, wind turbines, micro‐/nano‐electromechanical systems, atomic force microscopes, and biomedical devices are highlighted. This review is concluded with prospects on challenges and future directions in this critical field.

“…Obviously, the TiNbMoTaCr nanolayers interrupt the continuous growth of MoS 2 nanolayers and induce the renucleation and growth of thin MoS 2 nanolayers on the underlying TiNbMoTaCr nanolayers. In the growth stage of thin MoS 2 sublayers, surface energy minimization will dominate, producing (002) preferential growth. , Such preferential orientation on the MoS 2 (002) plane is generally considered to have excellent lubricity and low oxygen sensitivity, contributing to excellent tribological properties. , Simultaneously, the strong XRD peaks assigned to TiNbMoTaCr nearly disappear in the TiNbMoTaCr/MoS 2 nanomultilayers. Only the weak and hump-like peak at 40.4° can be found, suggesting a poor crystallinity.…”

The well-known integration of physical, chemical, and mechanical properties enables high-entropy alloys (HEAs) to be applied in various fields; however, refractory HEAs are brittle and susceptible to abrasive wear at high coefficients of friction (COF), resulting in insufficient mechanical durability against abrasion. Herein, curved MoS 2 nanosheets are periodically introduced into the TiNbMoTaCr film for triggering the selfassembly mixed metal oxides @MoS 2 nanoscrolls, which contain hard mixed metal oxides cores and the low-shearing lubricant MoS 2 shells, during the friction in the air environment; such mixed metal oxides@MoS 2 nanoscrolls in the friction interfaces can contribute to the robust low friction and low wear. Compared to the pure TiNbMoTaCr film (with high COF of ∼0.78, low abrasive durability identified by worn-out event), the periodic incorporation of 10 nm thickness curved MoS 2 sheets can successfully achieve a low COF of ∼0.08 and low wear rate of ∼9.561 × 10 −8 mm 3 / Nm, much lower than the pure MoS 2 film (COF = ∼ 0.21, wear rate = ∼ 1.03 × 10 −6 mm 3 / Nm). Such superior tribological properties originate from the cooperative interaction of TiNbMoTaCr nanolayers and curved MoS 2 nanosheets, accompanied by the self-assembly of mixed metal oxides@MoS 2 nanoscrolls. In these nanoscrolls, TiNbMoTaCr can act as an 'air-absorbing agent' to form high-loading mixed metal oxide cores and serve as an 'oxygen sacrificer,' preventing the low-shearing lubricant curved MoS 2 nanosheets from oxidation. In addition, even with the soft MoS 2 , the hardness of the TiNbMoTaCr/MoS 2 nanomultilayers can still be well maintained and increased above the calculated values by mixing law, further favoring superior mechanical durability. The synergetic effect of TiNbMoTaCr and curved MoS 2 nanosheets during the friction in air can provide a route to design HEA films with enhanced tribological properties for better mechanical durability and broader application prospects.

“…Regarding the coating, the coating is composed of epoxy resin and filler, which is composed of graphite, molybdenum disulphide and alumina. Graphite and molybdenum disulphide were used as solid lubricants because of their low coefficient of friction [33,34], Epoxy resin as adhesive has high strength, high viscosity, high chemical resistance and excellent insulation properties, so it is widely used in coatings, adhesives and other fields. Alumina is used as a functional filler to improve the load bearing and wear resistance of the coating.…”

Solid lubricating coatings were applied onto Carbon Fibre Reinforced Polymer (CFRP) substrates, using epoxy resin as the adhesive agent, graphite (C) and molybdenum disulphide (MoS2) as lubricating components, and alumina (Al 2 O 3 ) as the functional filler. The test parts were prepared by spraying technology and co-curing process. The mechanical properties of the coating were evaluated using Bar hardness and wear rate tests, while the microstructure of the coating was analysed using EDS elemental analysis technology. The test results revealed that the filler content had a significant impact on the mechanical properties. The performance of the coating was determined by the formation of a lubricating film, which resulted from the accumulation of lubricant and reinforcing material during external friction. Scheme T7 yielded the best coating performance with a ratio of epoxy resin to molybdenum disulphide to graphite to alumina of 20:8:3:2.
