This paper presents the tribological properties of MXene (Ti3C2Tx) coatings on the surface of impregnated zinc phosphate graphite. MXene coatings were deposited on the surface of the impregnated zinc phosphate graphite by the electrophoretic deposition method at different voltages of 5 V, 10 V, and 15 V. The tribological properties of the MXene coatings were investigated from room temperature to 400 °C in ambient air. The results show that MXene coatings are helpful to improve the tribological properties of the impregnated zinc phosphate graphite at elevated temperatures. The coatings deposited at 5 V have the best anti-friction behaviors among the coatings at the different deposition voltages, which indicates that the MXene coatings deposited at 5 V are suitable for applications in a wide range of temperatures, especially high-temperature environments. The average CoF of the coatings deposited at 5 V is about 0.18 at 200 °C, 0.25 at 300 °C, and 0.21 at 400 °C, respectively. The CoF of the coatings deposited at 15 V is relatively stable with the increase in temperature. Moreover, the high-temperature low-friction mechanism was discussed. The high-temperature low-friction mechanism is attributed to the good self-lubricating behaviors of the impregnated zinc phosphate graphite and the transfer film of the MXene coatings.

With the rapid development of the aerospace, automobile, and ocean industries, there is an urgent need for the fabrication of high-performance polymer matrix composites with low friction and wear in wide temperature ranges. In this paper, polytetrafluoroethylenes (PTFEs) doped with polyether-ether-ketone (PEEK), carbon fiber (CF), and TiC were prepared, and the effects of testing temperatures from room temperature to 250 °C in air conditions were investigated. The results showed that the friction coefficient of the PTFE matrix composites had no obviously changing trend, while the wear resistance properties were significantly improved. Due to the synergistic lubrication and enhancement of CF, PEEK, and TiC, the wear rate for composites with these particles decreased from (2.04–2.72) × 10−3 mm3/Nm for pure PTFE to (0.67–1.96) × 10−4 mm3/Nm. Moreover, the SEM analysis results showed that the main wear mechanisms are fatigue and abrasive wear for the PTFE matrix composites. The results obtained in this study will provide data and technical support for the development of high-performance polymer matrix composites with low friction and wear that can be used over a wide temperature range.
