, 2022 Abstract This paper focuses on the effect of mechanical shearing on the structure and properties of complex lithium greases with or without zinc dialkyl dithiophosphate (ZDDP). The base grease and grease with additives were first mechanically sheared by a roller shear tester, and then the tribological properties, rheological properties, micro ...

Tribological Performance of Non-halogenated Phosphonium Ionic Liquids as Additives to Polypropylene and Lithium-Complex Greases [PDF]
Tribology Letters, 2019 AbstractFour non-halogenated ionic liquids (ILs) with trihexyl(tetradecyl)phosphonium cation are tested as lubricant additives to polypropylene (PP) and lithium-complex (LiX) greases. In pin-on-disk tests at elevated temperatures, the addition of an IL with bis(oxalato)borate ([BOB]) anion reduces wear by up to 50% when compared to the neat LiX base ...

Tribochemistry and EP Activity Assessment of Mo‐S Complexes in Lithium‐Base Greases [PDF]
Advances in Tribology, 2008 The blends of bis(1,5‐diaryl‐2,4‐dithiomalonamido)dioxomolybdenum(VI) complexes in lithium‐base grease are evaluated for their extreme pressure activity in a “four‐ball test” using 12.7 mm diameter alloy steel ball specimen. The additive, bis(1,5‐di‐p‐methoxyphenyl‐2,4‐dithiomalonamido)dioxomolybdenum(VI) and bis(1,5‐di‐p‐chloro‐phenyl‐2,4 ...

Advanced Science, EarlyView.A biomimetic multi‐layer hygroscopic membrane redistributes salt toward an air‐accessible nanofiber interface, enabling rapid interfacial deliquescence while a brush‐like hydrogel promotes efficient liquid transport and storage. By decoupling vapor capture from bulk water storage, the membrane achieves fast sorption kinetics and enables rapid‐cycling ...
