Eco-friendly two-dimensional (2D) nanolubricants have emerged as promising candidates for advanced functional materials. However, challenges such poor dispersion stability and weak interfacial adhesion limit their widespread application. Herein, we developed a method to tailor WS2 nanosheets functionalized with γ-aminopropyltriethoxysilane (γ-APS), enhancing interaction phosphate ester groups from di(2-ethylhexyl) (DEPS), which leads the creation of gel-like WS2-NH-DEPS additives excellent dispersive tribological properties in polyalphaolefin (PAO6). Specifically, 0.5 wt % WS2-NH-DEPS/PAO6 achieves reduction ∼40% coefficient friction (COF) decrease ∼70% wear scar diameter (WSD) compared pure PAO6. Surface analysis reveals that unique structure exfoliated synergistic interactions phosphonate facilitate formation hybrid protective film composed embedded nanosheets, phosphoric acid compounds, other oxides FeOX, FeNOX, FeSOX enhance performance, providing essential insights developing nanomaterial-based lubricants mechanical systems.

This study investigates the performance of biobased and nano-additive lubricants for sustainable machining Al6082 alloy. The experiments were conducted in five different cutting environments: dry cutting, olive oil-based minimum quantity lubrication (MQL), sunflower MQL, MQL with nano-SiO2 additives, additives. was evaluated terms key parameters such as surface roughness, forces, tool wear, temperature, chip morphology. results show that reduce friction, thus providing lower roughness. nano-SiO2-additive method showed optimum by lowest force temperature values. It also determined contributed to more regular formation. reveals use nano-lubricants processes offers environmental economic advantages. In future, it is recommended examine types concentrations nanoparticles, conduct long-term wear analyses, evaluate effects on other methods.
