Nano-montmorillonite-doped lubricating grease exhibiting excellent insulating and tribological properties

Friction, 2017
Three types of nano-montmorillonite were doped as additives to afford lubricating greases. The physicochemical, insulating, and tribological performances of the obtained lubricating greases were investigated in detail.

An approach of the internal friction-dependent temperature changes for conventional and pure biogenic lubricating greases

Friction, 2023
This work investigated the temperature changes inside the bulk of lubricating greases under controlled high-shear stress conditions (250–500 s−1). For this purpose, a newly developed temperature-measuring cell called Calidus was successfully tested.
