The tribofilm formation of ZDDP under reciprocating pure sliding conditions [PDF]
, 2016 The anti-wear and anti-seizure performance and action mechanisms of zinc dithiophosphate (ZDDP) have been investigated under reciprocating pure sliding conditions to simulate piston ring and cylinder liner assembly, using new techniques.

Tribochemistry of bearing steels : A new AFM method to study the material-tribofilm correlation
, 2016 A new AFM method for relating microstructure to tribofilm formation is presented. Three aspects of this method distinguish it. Firstly, the new method maps the same region employing atomic force microscopy (AFM) in three sequential steps: preEDTA and ...

Understanding the Fundamentals of the Texture and Tribofilm Evolution
Procedia Manufacturing, 2020 Abstract Several manufacturing processes experience the interaction between and among mating surfaces under the boundary lubrication (BL) regime. Textures evolve as a result of these multi-parametric interactions where physical and chemical parameters play a significant role.

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 ...

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.
