Tribology of PTFE films
Nano-Tibology of A Polytetrafluoroethylene Transfer Films using atomistic Molecular Dynamics Simulation (MD) has been conducted. The specifics of the approach taken are given here: Nanotribology of PTFE. Macroscopic experimental tribology are often conducted at sliding velocities on the order of 0.5 m/s. Such velocities, from an MD standpoint, are extremely slow and may require years to obtain meaningful results. Consequently, the sliding velocities used in MD tribology simulations are usually at least an order of magnitude larger than those frequently used in experimental studies. The current study probes the effects of sliding velocity on the tribological properties of PTFE films. The goal is to obtain a range of simulation sliding velocities over which the tribological properties of PTFE are relatively unaffected by sliding velocity. The study is conducted within the contraints of the NVT emsemble.
