Tribological properties of glass fiber filled polytetrafluoroethylene sliding against stainless steel under dry and aqueous environments: enhanced tribological performance in sea water

Tribological performance evaluation of polytetrafluoroethylene composites under dry sliding and aqueous environments using taguchi approach and grey relational analysis: Effect of material, test environment and load

“…Therefore, for all the three PTFE composites it is the film formation in sea water that results in improved tribological performance than dry sliding and sliding in distilled water. Iron and chromium oxides are the major constituents of these films . These oxides have lubricating effect and thus these films formed in sea water are lubricious .…”

“…Several research investigations have been conducted to understand the tribological behavior of PTFE composites under dry and aqueous environments . Tanaka and Kawakami studied the tribological behavior of PTFE composites filled with different fiber and particle fillers against steel under dry sliding conditions and concluded that friction is independent of the type of filler and that the load supporting action and the preclusion of large‐scale damage of the banded structure of PTFE add to wear reducing action of fillers.…”

Effect of homologous molecular crosslinking on the tribological properties of PTFE composites

“…2,3 However, the limitations of PTFE, such as poor wear resistance, severe creep deformation, and easy wear, severely restrict its application as engineering plastic in actual production. To enhance the mechanical and tribological characteristics of PTFE, researchers have proposed techniques like the use of surface modification, [4][5][6][7] filling modification, [8][9][10] and blending modification. 8,[11][12][13] PTFE matrix composites were also obtained from the original binary composites, 3,14 the later multicomponent composites, 8,[15][16][17] and combinations of both methods.…”

Influence of high temperature on the tribological properties of hybrid PTFE/Kevlar fabric composite

“…The state of the transfer film during the friction process, however, is affected by many factors, such as contact parameters (contact stress [6][19] [20][21], sliding speed [6] [20] and frequency [20] etc.) and contact environment (water lubrication [22], vacuum [23] [24], ambient temperature, etc.). Notably, the properties of the self-lubricating fabric and the state of the transfer film are extremly susceptible to temperature [6].…”
