Experimental investigation to assess the effect of graphene blended lithium grease on friction, wear, and surface morphology of 52100 chrome alloy steel contacts
The results of a research on the tribological behaviour of lithium grease with the addition of graphene nanoparticles are presented in current work. Using a four-ball tribometer, the wear and friction coefficient of lithium grease and blended grease samples with graphene additions were assessed. The significance of graphene in enhancing the tribological properties of grease materials is evident from experimental results. In the experimental investigation, a considerable decrease in wear and friction co-efficient values was also noted. One weight percent addition of graphene to base grease decreases friction by 23.73% and wear scar width by 19.51%.
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.
