How Polytetrafluoroethylene Lubricates Iron: An Atomistic View by Reactive Molecular Dynamics

Qiang Xu et al.

Summary: The tribochemistry and transfer film formation at the metal/polymer interface have important implications for surface protection, wear reduction, and lubrication. Through molecular dynamics simulations, this study reveals the mechanisms of tribochemical reactions between iron and polytetrafluoroethylene (PTFE), as well as the formation of transfer films. The results show that mechanical shearing leads to the degradation of PTFE molecules and radicals, followed by oxidation and hydroxylation reactions. Additionally, the study highlights the role of a friction-induced oriented molecular layer in reducing friction and achieving excellent lubrication.

Quantitative measurement of transfer film thickness of PTFE based composites by infrared spectroscopy

Yanqi Gu et al.

Summary: A method for quantitatively characterizing the thickness of PTFE/alpha-alumina composites transfer films was proposed based on chemical and morphological analysis, showing a linear correlation between the peak area of the CF2 antisymmetric stretching vibrational absorption peak and transfer film thickness. This provides a simple, rapid, and nondestructive approach for measuring polymeric transfer film thickness.
