On the Crystallinity and Durability of ZDDP Tribofilm [PDF]
Tribology Letters, 2019 Abstract The current trend for using lower-viscosity lubricants with the aim of improving fuel economy of mechanical systems means that machine components are required to operate for longer periods in thin oil film, mixed lubrication conditions, where the risk of surface damage is increased. Consequently, the performance and durability of

Synthesis of ultrathin two-dimensional metal-organic framework nanosheets for lubricant additives
Materials & Design, 2022 Two-dimension (2D) nano materials are diffusely employed as lubricant additives. In this paper, three kinds of ultrathin 2D metal-organic framework (MOF) nanosheets with different metal ions (Ni2+, Zn2+, and Cu2+) were successfully synthesized by ...

Scuffing failure analysis based on a multiphysics coupling model and experimental verification
Friction, 2023 General reductions in lubricant viscosities and increasing loads in machine components highlight the role of tribofilms in providing surface protection against scuffing. However, the relationship between the scuffing process and the growth and removal of

Tribofilms Forming in Oil-Lubricated Contacts [PDF]
Lubricants, 2016 The subject of the present paper is the characterization of third bodies of run-in systems. By means of continuous friction and wear measurement, lubricated steel-steel and steel-aluminum contacts were evaluated. Microstructure, chemical composition and response of the materials to shear were analyzed by XPS/AES and focused ion beam technique.

Self-healing WS2 tribofilms: An in-situ appraisal of mechanisms [PDF]
Scripta Materialia, 2021 Self-healing tribocoatings are being developed for aerospace applications to improve the lifetime and reduce the surface maintenance of components in motion. Here the tribo-induced self-healing behaviour of a WS2/a-C tribocoating has been evaluated for the first time by in-situ scanning electron microscopy (SEM) to evaluate the mechanisms of damage and
