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 ...

On an Elastoplastic Sliding Model for a Coated Single Asperity
Lubricants, 2018 In this study, a sliding friction model for coated single asperity contacts is proposed. A displacement-driven layered contact algorithm is firstly introduced and verified by the finite element method.

Dynamics of Tribofilm Formation in Boundary Lubrication Investigated Using In Situ Measurements of the Friction Force and Contact Voltage. [PDF]
Materials (Basel)The complex dynamics of tribofilm formation on boundary-lubricated steel surfaces were investigated in real time by combining in situ measurements of the temporal variation of the coefficient of friction and contact voltage.

Influence of slide-to-roll ratio on tribofilm generation
, 2008 International audienceRolling contact fatigue has become a surface initiated problem. This phenomenon is due to the initiation and propagation of cracks from the surface to the volume of mechanical pieces.

Modeling of Formation and Removal of ZDDP Tribofilm on Rough Surfaces
, 2021 Zinc dialkyldithiophosphate (ZDDP) is a widely used lubricant additive due to its high effectiveness in reducing wear by forming a tribofilm on sliding surfaces. However, the formation and removal of tribofilm are two competing processes depending on the

The Distribution of Zinc in Low-Friction ZDDP Tribofilm on Iron Oxide
Tribology Online, 2009 To develop a low-friction and low-wear tribo-system for engine components, the authors have been studying the ZDDP tribofilm formed on iron oxide. Tribotests on iron-oxide / steel sliding pairs were performed in PAO with 1 mass% ZDDP.

Mechanism of tribofilm formation on Ti6Al4V oxygen diffusion layer in a simulated body fluid [PDF]
, 2018 An Oxygen Diffusion Layer (ODL) was generated on the surface of Ti6Al4V alloy by thermal oxidation treatment. In vitro tests for cytotoxicity were performed in the presence of Ti6Al4V and the ODL samples with the culture of G292 Cells and using MTT assay.
