Molybdenum disulfide (MoS2) has a typical layered structure and is widely used in the lubrication field. However, its nanosheets are difficult to disperse prone agglomeration lubricating oil, which makes it challenging achieve ultralow friction atmospheric environment restricts practical applications. Therefore, of great significance solve problems MoS2 realize friction. In this paper, synthesized by hydrothermal method were taken as target material, tremella-like nanospheres successfully prepared laser irradiation liquid. This technique realizes reshaping morphology under normal temperature pressure simple, clean, efficient. Importantly, these unique nanospheres, additives for glycerol, can not only effectively inhibit aggregation nanomaterials, possessing excellent dispersion stability good wetting properties, but also significantly reduce wear rate, enabling system long-term environment. The analysis worn surfaces indicates that effective formation tribofilm self-storage characteristics key factors achieving research promotes application materials engineering field provides theoretical basis development new lubricants.

Two-dimensional (2D) materials are known to induce excellent solid lubrication performance. However, their performance largely depends on the ambient conditions (working atmosphere), since moisture and oxygen deteriorate frictional properties of MoS2 MXenes. Currently, little knowledge is available regarding humidity-dependent tribological MXene coatings. Therefore, our contribution aims at experimentally evaluating multilayer Ti3C2Tx/MoS2 hybrid coatings used as lubricants dependent relative humidity (10, 35, 70%). For this purpose, mixed (50% Ti3C2Tx 50% MoS2) bilayer (bottom top layer were deposited via spray-coating chromium steel discs be tested under dry reciprocating using ball-on-disk tribometry. Our results show that both performed best low humidities, thus notably improving resulting friction wear The favorable mechanism was mainly attributed low-shear stress between sulfides derived from MoS2. At higher formation oxides detrimentally affected lubrication, causing increase leading more pronounced wear. This study sheds light underlying mechanisms governing for MXene/MoS2 different levels.

Metal-organic framework (MOF) nanoparticles have attracted widespread attention as lubrication additives due to their tunable structures and surface effects. However, solid properties been rarely explored. This work introduces the positive role of moisture in case a newly described Ti-based MOF (COK-47) powder. COK-47 achieves an 8.5-fold friction reduction compared AISI 304 steel-on-steel sliding under room air. In addition, maintains similarly low coefficient (0.1-0.2) on various counterbodies, including Al2O3, ZrO2, SiC, Si3N4. Notably, other widely studied MOFs (ZIF-8, ZIF-67) 2D materials powder (MXene, TMD, rGO), exhibits lowest (≈0.1) same experimental settings. Raman spectroscopy, X-ray diffraction, photoelectron energy dispersive scanning electron microscope, transmission microscopy indicate that tribofilm is amorphous film obtained by hydrolysis air with moisture. Density functional theory further confirms water catalyzes decomposition COK-47, crucial step forming tribofilm. study demonstrates idea utilizing water-assisted mechanisms. It provides new insights into applications tribology highlights interdisciplinary contributions mechanical engineering chemistry.
