Improvement of the Tribological Properties of a Lithium-Based Grease by Addition of Graphene

Journal of Nanoscience and Nanotechnology, 2018
Graphene with layer number less than seven, prepared by a mechanical exfoliation method, was used as a friction-reducing additive to a lithium-based grease. The graphene was characterized via AFM, TEM, and Raman spectroscopy. The as-prepared graphene had few defects according to the characterization analysis and appeared to be composed primarily of ...

Rheological properties of lithium, lithium complex, and sodium greases

Journal of Synthetic Lubrication, 1993
AbstractThe rheological properties of two lithium, two lithium complex, and two sodium greases, all with the most common NLGI grade two, have been investigated. The greases are based on a mineral and a synthetic oil. The apparatus used was a cone‐and‐plate rheometer and an impacting‐ball apparatus.The impacting‐ball apparatus used a steel ball, which ...

A rheological model for lithium lubricating grease

Tribology International, 1998
The rheological properties of a lithium lubricating grease were examined under various settings of shear rate, time and temperature with an emphasis on the thixotropy of grease. A HAAKE RV 20 rheometer was employed in the experiments, utilizing a cone and plate configuration.

Thermorheological behaviour of a lithium lubricating grease

Tribology Letters, 2006
Thermal-induced changes in the viscous and viscoelastic responses of lubricating greases have been investigated through different rheological techniques in a temperature range of 0–175 °C. Small-amplitude oscillatory shear and viscous flow measurements were carried out on a model conventional lithium lubricating grease prepared by inducing the in situ ...

Continuous manufacture of lithium lubricating greases

Chemistry and Technology of Fuels and Oils, 1968
1. It is shown that a continuous plant can be used to manufacture TsIATIM-201 grease from a soap-oil dispersion with stiffener content 12%. 2. It has been established that the properties of the grease are greatly affected by the alkali content, the discharge temperature of the fused system from the heater, and the homogenization ...
