The article studies the influence of graphene fluoride on the structure and properties of greases by optical microscopy, rotational viscometry and tribometry. The tribological properties of the basic and modified lubricating compositions were evaluated using a four-ball friction tester according to the main indicators: the average diameter of the wear spot, the load-wear index, the critical load and the welding load. Rheological studies showed that the introduction of graphene fluoride into the studied basic lubricating compositions increased their viscosity properties and had a positive effect on the strength of the frame structure of the thickener. The study of the microstructure of the samples showed that graphene fluoride is an active component of the system and participates in the process of structure formation of greases. Tests showed an improvement in the tribological properties of modified lubricating compositions. The prospects of using graphene fluoride as a friction modifier for greases was confirmed.
