“…Similar to sliding velocity, by increasing the load conditions from 10 N to 20 N, the friction coefficient was highly impacted. [ 35,43 ] By the effect of sliding velocity, the friction coefficient reduces initially and it tends to increase. [ 35 ] Besides, the PTFE composite gets weakens at maximum sliding conditions.…”

In Industries, polytetrafluoroethylene (PTFE) is used as a solid lubricant due to its excellent toughness, lack of reactivity, high-thermal stability, and so forth. However, the abrasive resistive behavior is minimal for the virgin PTFE polymer. In this study, the wear and coefficient of friction (COF) of PTFE composite prepared by the combination of 10% halloysite, 10% graphite, and 10% bronze are investigated. The investigations are performed on a pin-on-disc test rig and analysis is done by response surface methodology (RSM), especially in Box-Behnken Design (BBD). The experimentation is performed by varying the sliding distance (Ds), sliding velocity (Vs), and applied load (L). In the analysis of COF, the load is considered as a significant parameter, and sliding distance is an influencing parameter for wear rate. From the experimentation, the proposed PTFE composite promotes COF of 0.0052 and a wear rate of 0.62 Â 10 À5 mm 3 /Nm. Such observed wear rate and COF are 2.8 times and 1.5 times better than the pure PTFE. The experimented outcomes are validated using hybrid DBN-based bald eagle search optimization (DBN-BESO), and RSM. From the validated results, the proposed hybrid DBN-BESO prediction process using the Matlab platform promotes closer values to the experimented outcomes. Besides, the parametric optimization is conducted using RSM and BESO approaches with the objective of minimum wear rate and COF. The optimized BESO results are superior to the RSM. BESO-based optimized wear rate is 0.0317 Â 10 À5 mm 3 /Nm and COF is 0.0352.

“…In other words, the 5% nano clay contributed PTFE promotes more than100 times more wear‐resistant than the plain PTFE. Zuo et al [ 35 ] examined the tribological behaviors of polyethersulfone (PES) blended with PTFE. The wear resistance and anti‐friction behaviors are superior to the virgin PTFE when using 40% of PES with PTFE.…”

Electrophoretic deposition (EPD) coating has become a hot topic due to its simple experiment, wide application, and wide material range. In this study, the PTFE coating was successfully prepared by electrophoretic deposition through the systematic study of electrophoretic deposition kinetics. In particular, in the dispersion system with ethanol as solvent, Nafion and NaOH were simultaneously added as additives to obtain a beneficial synergistic effect on PTFE electrophoretic deposition. And the best additive scheme is: when the concentration of PTFE was 6 g·L− 1 and the deposition time was increased to 20 min, adding 0.10 g·L− 1 Nafion and 0.10 mM NaOH simultaneously. Compared with the scheme with Nafion being only additive, the addition of NaOH can improve the deposition rate from 0.16 mg·cm− 2 to 0.98 mg·cm− 2, and the deposition rate increases by about 6 times. According to electrophoretic deposition kinetics, there is an obvious critical transition time between linear and parabolic regions in the preparation of the coating. Prolonging the arrival of critical transition time is beneficial to effectively achieve stable growth of the coating in a longer time. It is found that a more ideal additive can not only increase the deposition rate of coating, but also significantly accelerate the arrival of critical transition time. Meanwhile, the deposition voltage also has an important influence on the critical transition time. Increasing the voltage can improve the deposition speed but shorten the critical transition time. Therefore, the application of deposition voltage needs to strike a balance between deposition rate and critical time point. The optimal deposition conditions proposed in this work are: deposition voltage 60 V, deposition time 20 min, additive 0.10 g·L− 1 Nafion and 0.10 mM NaOH.

“…Without sacrificing the characteristic low friction of PTFE, its wear resistance can be improved by adding fillers to the PTFE matrix. Zuo et al [196] effectively improved the abrasion resistance of polyethersulfone (PES)/PTFE-based polymers by using lamellar sodiummontmorillonite (NaMMT) as reinforcing filler, due to the load bearing of NaMMT on the worn surface. Levin et al [197] successfully enhanced the friction and wear reduction properties of WS 2 -inorganic nanotubes (INTs) with the addition of PTFE nanospheres using bath sonication.…”
