Impact of Lubricant Additives-Soot Interactions on the Tribological Properties of Lithium Grease
Among atmospheric contaminants, soot is known to cause severe wear of mechanical components and degrade lubricating oils; however, its impact on lubricity grease remains largely unexplored. This study investigates the interactions between carbon black (as a soot surrogate) and other lubricant additives, including molybdenum disulfide (MoS2) and anti-wear additive zinc dialkyldithiophosphate (ZDDP). Additionally, the effects of individual and combined additions of MoS2 and ZDDP on the tribological properties of soot-contaminated lithium grease (LG) were compared. The lubricity of LG decreased progressively with increasing soot concentration. Conversely, incorporating MoS2 improved the lubricity of LG, with optimal performance observed at 0.5 wt%. The individual addition of MoS2 to LG minimally mitigated the abrasive wear caused by soot; however, the inclusion of ZDDP T202 enhances the effectiveness of MoS2 in reducing the friction and wear. MoS2 and ZDDP participate in tribochemical reactions to form protective films during sliding. MoS2 contributes by reducing friction, while ZDDP reacts to form protective films that enhance wear resistance. However, the combined addition of ZDDP and MoS2 demonstrates limited effectiveness in fully mitigating the adverse effects of soot on grease lubrication. Consequently, exploring more efficient methods to prevent lubrication failure caused by soot.
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.
