Rheological and Tribological Properties of Lithium Grease and Polyurea Grease with Different Consistencies

Coatings, 2022
The rheological properties of lithium grease and polyurea grease at different temperatures and consistencies were determined with a rotary rheometer. The plateau moduli of the greases were calculated, and the mechanism of influence of consistency and temperature on the rheological properties of the greases was explained.
