Influence of external load on friction coefficient of Fe-polytetrafluoroethylene

doi:10.1088/1674-1056/ab7da0

Abstract A coarse-grained molecular dynamics simulation model was developed in this study to investigate the friction process occurring between Fe and polytetrafluoroethylene (PTFE). We investigated the effect of an external load on the friction coefficient of Fe-PTFE using the molecular dynamics simulations and experimental methods. The simulation results show that the friction coefficient decreases with the external load increasing, which is in a good agreement with the experimental results. The high external load could result in a larger contact area between the Fe and PTFE layers, severer springback as a consequence of the deformed PTFE molecules, and faster motion of the PTFE molecules, thereby affecting the friction force and normal force during friction and consequently varying the friction coefficient.
