Abstract

Lubricant composition plays a crucial role in reducing wear and friction between moving components, thereby ensuring the smooth operation and protecting critical components of industrial machinery. Friction modifiers, as key additives, play a significant role in lowering the coefficient of friction and improving the energy efficiency of lubricants. In this study, we investigated the influence of friction modifier chemistry and concentration on the physico-chemical and tribological properties of industrial lubricating oil. Results demonstrated that increasing the friction modifier concentration effectively reduces the friction coefficient in tribological tests and enhances the elastohydrodynamic film thickness. Furthermore, the study highlights the significant role of surface temperature in activating the friction modifier. These findings provide valuable insights for the design of energy-efficient lubricants with optimised performance characteristics.

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.
