Abstract

Utility of aromatic extracts as fluid for preparation of calcium complex greases was investigated. The physicochemical properties of three grades of these extracts were initially studied. The rheological behavior (viscosity, shear stress and shear rate) of the individual aromatic extracts, and the obtained greases from those extracts at different temperatures were also illustrated. The rheological properties of both aromatic extracts and all lubricating greases were properly fit with the mathematical model of Herschel-Bulkley. Moreover, the flow behavior of the aromatic extracts as well as the corresponding lubricating greases was non-Newtonian. The study exhibited promising results concerning the thermal, mechanical and rheological properties for the prepared greases. Hence, in this work the by-product aromatic extracts act as a good alternative fluid for calcium complex lubricating greases.
