Temperature Resistance of Greases Thickened with Calcium Sulfonates

In this paper, we present the results of temperature tests of plastic lubricants prepared based on calcium sulfonates. For the preparation of greases, thickeners with various alkaline numbers and base oils differing in their structural and group composition were used. The tested greases showed simil...

Summary:In this paper, we present the results of temperature tests of plastic lubricants prepared based on calcium sulfonates. For the preparation of greases, thickeners with various alkaline numbers and base oils differing in their structural and group composition were used. The tested greases showed similar dynamics of temperature changes in the friction coefficient, which is associated with an identical mechanism of action of the sulfonate thickener during the formation of a modified surface layer. Samples with S-300 “A” thickener and the dispersion media VHVI-4 and S-9 oils have an optimal combination of physicochemical and tribological properties.
