Here, a strategy for designing self-lubricating medium entropy alloy (MEA) composites with high strength and excellent anti-wear performance was proposed through quasi-continuously networked in-situ carbides and graphene nanosheets. The discontinuous coating of graphene on the MEA powder surface inhibits continuous metallurgy bonding of the MEA powders during sintering, generating the typical quasi-continuously networked architecture. A good combination of mechanical properties with high fracture strength over 2 GPa and large compressive plasticity over 30% benefits from metallurgy bonding that prevents crack initiation and extension. The wear rate of an order of 10−6 m3·N−1·m−1 ascribing to an amorphous-crystalline nanocomposite surface, tribo-film induced by graphene, as well as the gradient worn subsurface during friction was achieved by the MEA composite, which is an order of magnitude lower than the unreinforced MEA matrix.

The coal mine environment is harsh. During the operation of a friction hoist, different media are often mixed between the friction lining and the steel wire rope. In order to explore the appropriate forms of lifting acceleration under different contact interface media and to investigate the influence of different contact interface media on the strain and friction performance of friction linings under different acceleration forms, this paper simulates the mine environment and conducts four different forms of lifting acceleration friction experiments via a dynamic micro sliding friction experimental platform with a friction lining and steel wire rope. The strain and friction performance changes of friction linings are analyzed through digital image correlation (DIC) technology. The results show that under different contact interface media, the strain change amplitude of the friction lining is the smallest under the trapezoid acceleration form, and the stability of the friction transmission is the best. Under trapezoid acceleration conditions, the friction force, friction coefficient, and strain amplitude of the friction-enhancing grease medium are the smallest, the maximum strain value decreases by 45.6%, and the friction force decreases by 64.3%, which has the greatest impact on the friction transmission performance of the friction lining. This paper provides guidance for the safe operation of friction type hoists.

The sliding wear results showed that the B4C/CS/SiO2 coating improves the surface quality under the synergistic effects of boron carbide, chitosan, and silica, and significantly reduces friction coefficients and wear rates. The friction shear force of the B4C/CS/SiO2 coating increases due to its high hardness and elastic modulus, resulting in a high friction coefficient. However, its high hardness and dense internal structure contribute to wear reduction. Friction experiments under simulated body fluid demonstrate that friction coefficient is reduced by calcium and phosphorus. Electrochemical experiments reveal that all three composite coatings significantly reduce the corrosion rate, and the B4C/CS/SiO2 coating exhibits the best anti-corrosion performance. The in vitro mineralization and cell culture experiments demonstrate that the B4C/CS/SiO2 coating has excellent cell proliferation and osteogenic properties, which are attributed to its improved hydrophilicity, increased roughness, and stimulation from Si4+. The antibacterial experiments show that the B4C/CS/SiO2 coating has excellent antibacterial performance, and the antibacterial rate reached 99.58%.

We studied the frictional properties at the homogenous interfaces of PG/PG and B2N4/B2N4, and the heterogenous interface of B2N4/PG. Our calculations show that the friction coefficients at the homogenous interface of B2N4/B2N4 are smaller than those at the heterogenous interface of B2N4/PG. The different compositional elements at the commensurate contacting surfaces hardly reduce the interlayer friction. It indicates the ineffectiveness of heterogenous interface on reducing friction when it is commensurate contacting. Additionally, the incommensurate contact formed via biaxial stretching one layer can significantly reduce the interlayer friction, which is the superposition of uniaxial stretching. In addition, the interlayer friction was elucidated from the point views of potential energy, charge density difference, and registry index (RI). This study highlights the importance and effectiveness of twisting in reducing the interlayer friction compared to stretching.

Researchers have investigated porous polymer materials as potential solutions; however, achieving exceptionally low friction and wear has proven elusive. To address this issue, we developed a novel porous fluorinated polyimide (PPIF-250) characterized by superior mechanical performance, heat resistance, and higher oil content and retention than other porous polyimide (PPI) with comparable pore sizes and porosities. Extensive lubrication testing under varying conditions has demonstrated that PPIF-250 achieves remarkably low friction and wear characteristics, even under high FV (force × velocity) values, representing a significant advancement in this field. Furthermore, our findings indicate that the polarity of base oils plays a crucial role in determining the oil content and retention of PPIF-250. Specifically, the integration of polyethylene glycol 200 (PEG200) with a tailored PEG-200 structure results in significantly improved oil content, retention, and long-term lubrication relative to those of other base oils. This improvement is attributed to the formation of high-load capacity boundary films within the PPIF-250 matrix, comprising oxidation processes involving carboxyl functional groups that chelate with iron or its oxides, alongside multilayer adsorption films stabilized by intermolecular hydrogen bonding and van der Waals forces. These insights will be instrumental in the development of more efficient and effective lubrication materials to meet the demands of modern technology.

Herein, oxidized graphene-functionalized composite lithium soap fibers (CLF/PG), exhibiting high oil affinity, were utilized to form a hydrogen bond network with epoxy resin (EP), constructing an effective oil retention network. By integrating dynamic micellar loading-desorption technology with a dual-spray gun system, we achieved uniform dispersion of oil microdroplets (G2825) within the oil retention network, ultimately fabricating a composite coating (C-G/EP). Notably, the 1.0 wt.% C-G/EP exhibited a wear rate of merely 0.212×10⁻⁵ mm³/N·m after 80,000 friction cycles - a remarkable 98.14% reduction compared with EP. Concurrently, the system maintained a stable average friction coefficient of ~0.031. Molecular dynamics simulations revealed that oil microdroplets integration within the hydrogen-bonded network simultaneously enhanced bulk and shear moduli while reducing Young’s modulus. The modulus reconfiguration facilitates a transition from rigid contact to micro-elastic deformation behavior at friction interfaces. This deformation behavior, synergizing with the load-bearing abilities of CLF and PG, enhances the lubrication film’s strength, thereby shifting C-G/EP’s lubrication state from boundary lubrication to elastohydrodynamic lubrication.
