“…Multifunctional additives, a kind of lubricant additives which are able to simultaneously enhance the oxidation stability of lubricants, reduce wear and friction of mechanical systems, have been extensively used and studied for the past few years (Wang et al , 2020; Palola et al , 2020; Karpov et al , 2019). Zinc dialkyldithiophosphate (ZDDP) is the most widely used multifunctional lubricant additive for its high efficiency and low-cost (Dörr et al , 2019; Massoud et al , 2020).…”

Purpose This paper aims to contrastively investigate the antioxidant behavior and tribological performance of a novel multifunctional additive (PBT) and dialkyldithiophosphate (ZDDP) in complex lithium grease (CLG). Design/methodology/approach PBT was successfully synthesized through esterification reaction. The antioxidant behavior of PBT and ZDDP was investigated by thermal analysis, and meanwhile, their tribological performance was evaluated by Optimol SRV-IV oscillating reciprocating friction and wear tester (SRV-IV test) and MRS-1J four-ball tester (Four-ball test). Furthermore, their anticorrosion ability was determined by copper strip corrosion test. Findings Four-ball tests showed that the extreme pressure property of PBT was a little inferior to that of ZDDP. Besides, all the other results demonstrated that PBT showed more superior antioxidation stability, friction-reduction and antiwear ability, as well as anticorrosion performance than ZDDP. Originality/value This work provides a study of hindered phenol derivative as a multifunctional additive in lubricant grease, which can contribute to the development of substitution of ZDDP.
