Abstract
Six lithium complex greases (LCGs) were prepared by 12-hydroxystearic acid, LiOH and different complexing agent (azelaic acid, sebacic acid, dodecanedioic acid, as well as the mixture of boric acid and each binary acid in a molar ratio of 1:1 (B/A=1:1, B/S=1:1, and B/D=1:1)), thickening polyalphaolefin (PAO 40). The effect of complexing agent on physicochemical, rheological and tribological properties was investigated. Results indicate that adding boric acid introduces the coordination bond that enhances the thixotropic, yield stress, physicochemical and tribological properties of LCG with onefold complexing agent. The LCG prepared by B/D= 1:1 presents the optimum physicochemical and tribological properties. The LCG was degraded during the friction and a tribo-chemical film formed (iron oxide, Li2O, and LiBO2/ B2O3).
