Abstract
Purpose
The purpose of this paper is to investigate the effect of SiO2 on the tribological properties of polytetrafluoroethylene (PTFE) composites from an atomic level.
Design/methodology/approach
Effect of SiO2 on the tribological properties of PTFE sliding against Cu was studied by molecular dynamics (MD) simulations to explore the inherent mechanisms from an atomic level.
Findings
SiO2 had a higher interaction energy with PTFE than copper, which contributed to an increase of interfacial temperature and velocity with severe adhesive wear on the PTFE molecules.
Originality/value
This study reveals the mechanism of SiO2 on the friction and wear behavior of PTFE by MD simulation.
