Tribological properties of polyimide composites reinforced with fibers rubbing against Al2O3
Friction, 2020 Reinforcing fillers are of great importance in tribological performance and tribofilm formation of polymeric composites. In this study, the tribological properties of aramid particle (AP) and short carbon fiber (SCF) reinforced polyimide (PI) composites ...

Shear activation of ZDDP reaction films in the presence and absence of nanodiamonds
Applied Surface Science Advances, 2022 We explore the impact of shear stress and nanodiamond (ND) additives on the formation temperatures of thermal- and tribo- reaction films of steel samples immersed in basestock oils containing zinc dialkyl dithio-phosphate (ZDDP) additives.

Film Thickness and Friction of ZDDP Tribofilms [PDF]
Tribology Letters, 2019 Tribofilm formation by several zinc dialkyl- and diaryldithiophosphate (ZDDP) solutions in thin film rolling-sliding conditions has been investigated. A primary, a secondary alkyl and a mixed alkyl ZDDP show similar rates of film formation and generate films typically 150 nm thick.

The Run-in Process for Stable Friction Fade-Out and Tribofilm Analyses by SEM and Nano-Indenter
Tribology Online, 2017 It was shown in previous reports by authors that friction coefficients of the level of 0.0001 were achieved when ZrO2 (Y-PSZ: yttria partially stabilized zirconia) pins were slid against diamond-like carbon (DLC) films in H2-gas environment under heavy ...
