“…Their enhancement order from high to low for such effect is PTFE, graphite and MoS 2 . The research works from Suzuki and Prat [8] showed that there was a transfer of PTFE on steel surface when PTFE sliding against steel counterpart, nevertheless, if a MoS 2 sputtered film existing on steel surface,…”

“…This indicates that the thin transfer PTFE film depletes in this region, presumably due to abrasive/adhesion wear to a point where metal-metal contact starts to occur. The appearance of a very small peak at 684.8 eV binding energy might be due to the formation of metal fluoride which has been reported as a decomposition product of PTFE in other wear studies [15,20]. At the final stage of the Amsler test when μ reaches 0.60 (sample G), the PTFE signals are very small and the metal-metal contact is no longer lubricated by PTFE.…”

“…A number of tribological studies on PTFE have been published, however their focus was mainly on friction and wear performance under pure sliding conditions [11,13]. Due to an increased interest in space applications such as hybrid bearing, the transfer film lubrication of PTFE or its composite under a combination of rolling and sliding have been studied under extreme environment conditions (at cryogenic temperatures [14], or in vacuum [15]). Information is still limited regarding its tribological behavior at wheel/rail interface under hybrid rolling and high contact pressure.…”

“…In the process, MoS 2 and its derivatives (MoO 2 , MoO 3 ) caused the upsurge in the friction coefficient . Some metal fluorides have been reported to increase the friction coefficient of PTFE composites …”
