The Investigation on Rheology and Microstructure for Lithium Complex Grease
Energy and Earth Science, 2019 The rheological characteristic parameters of five lithium complex lubricating greases were determined. The comparison of rheological characteristic parameters and microstructure of the five greases was made. The results showed that the knowledge of the rheological properties of lubricating greases may contribute to reflect the change of the thickener ...
