Abstract

The ILs ([Li (synthetic esters)] NTF₂) were prepared by the in situ synthesis method. The tribological behaviour of the ILs to friction pairs of Ti-6Al-4V titanium alloy against silicon nitride was studied by SRV-V under different concentrations and friction frequencies; the wear scar was studied by SEM, XPS and TOF-SIMS. The results showed that the friction coefficient and wear loss decreased gradually with the increase of the LiNTF₂ content; when the LiNTF₂ content reached a certain value (10%), the friction coefficient and wear loss did not change much. Tribofilm composed of titanium oxide, Al₂O₃, TiFO₂, AlOF₂, Ti₂O₄F and Al₂O₃F plays a major role in lubrication and anti-friction effect.

ILs（[Li（合成酯）] NTF2）对 TC4 钛合金氮化硅的润滑机制

通过原位合成法制备了ILs（[Li（合成酯）] NTF2）。在不同浓度和摩擦频率下，通过 SRV-V 研究了 ILs 对 Ti-6Al-4V 钛合金与氮化硅摩擦副的摩擦学行为；通过 SEM、XPS 和 TOF-SIMS 研究了磨损痕。结果表明，随着 LiNTF2 含量的增加，摩擦系数和磨损损耗逐渐减小；当 LiNTF2 含量达到一定值（10%）时，摩擦系数和磨损损耗变化不大。由氧化钛、Al2O3、TiFO2、AlOF2、Ti2O4F 和 Al2O3F 组成的三膜在润滑和减摩方面发挥了重要作用。

期刊介绍： Lubrication Science is devoted to high-quality research which notably advances fundamental and applied aspects of the science and technology related to lubrication. It publishes research articles, short communications and reviews which demonstrate novelty and cutting edge science in the field, aiming to become a key specialised venue for communicating advances in lubrication research and development. Lubrication is a diverse discipline ranging from lubrication concepts in industrial and automotive engineering, solid-state and gas lubrication, micro & nanolubrication phenomena, to lubrication in biological systems. To investigate these areas the scope of the journal encourages fundamental and application-based studies on: Synthesis, chemistry and the broader development of high-performing and environmentally adapted lubricants and additives. State of the art analytical tools and characterisation of lubricants, lubricated surfaces and interfaces. Solid lubricants, self-lubricating coatings and composites, lubricating nanoparticles. Gas lubrication. Extreme-conditions lubrication. Green-lubrication technology and lubricants. Tribochemistry and tribocorrosion of environment- and lubricant-interface interactions. Modelling of lubrication mechanisms and interface phenomena on different scales: from atomic and molecular to mezzo and structural. Modelling hydrodynamic and thin film lubrication. All lubrication related aspects of nanotribology. Surface-lubricant interface interactions and phenomena: wetting, adhesion and adsorption. Bio-lubrication, bio-lubricants and lubricated biological systems. Other novel and cutting-edge aspects of lubrication in all lubrication regimes.
