“…The mean TF thicknesses were from 2.5 to 11.0 µm but did not show a direct correlation to WR levels because the lowest values were observed for the mean TF thicknesses less than 4 μm (PEEK; P-o-D, Ra(PEEK) = 0.2 μm; counterpart is a steel pin of 56.6 HRC with a diameter of 20 mm; R a (steel) = 0.5 μm; RT; V = 0.1 m/s; P = 60 and 125 N; CP = 1.8 and 3.9 MPa; DSF). Yan, et al investigated a series of PEEK-based composites loaded with different PI contents (10–50%) [ 110 ]. Thermal endurance, friction-reducing capacity, and wear resistance were improved by filling with PI.…”

The purpose of this review is to summarize data on the structure, mechanical and tribological properties, and wear patterns of composites based on high-performance polymers (HPPs) intended for use in friction units. The review includes three key sections, divided according to the tribological contact schemes regardless of the polymer matrix. In the second part, the analysis of composites is carried out in point contacts. The third section is devoted to the results of studies of HPP-based composites in linear ones. The fourth section summarizes information on flat contacts. Particular attention is paid to the formation of transfer films (TFs) in the contacts and their influence on the tribological patterns of the studied rubbing materials. As a conclusion, it is noted that the challenge of experimental methods for analyzing TFs, stated by K. Friedrich, is effectively solved in recent studies by the XPS method, which enables us to accurately determine their composition. Although this determination is completed after the tribological tests, it allows not only a more accurate interpretation of their results considering specific conditions and loading schemes, but also the ability to design HPP-based composites that form required TFs performing their preset functions.

“…Meanwhile, when the composite material produces microcracks due to friction, CNT can effectively inhibit the growth of microcracks, reduce grinding chips, and improve the wear resistance of the material (Bahramnia et al, 2021). The CNT incorporation also improves the thermal conductivity and thermal stability of the composite material, preventing it from softening under the high temperature conditions of frictional heating and failure, which affects wear resistance and service life (Shimizu et al, 2020;Yan et al, 2020).…”

With the development of modern industry, the requirements for mechanical equipment are increasingly stringent, and increasing attention has been paid to reducing wear or lubrication in the movement of mechanical structural parts. Polymers are widely used in the field of mechanical structural parts due to their high processing performance and comprehensive performance. However, the relatively weak mechanical and tribological properties of polymers limit their further application in mechanical equipment lubrication. Incorporation of fillers is a common method to improve the friction properties of polymers. Among various fillers, carbon nanotubes (CNTs) are considered the ideal fillers to significantly improve the tribological properties of polymers. Therefore, this paper reviews the tribological properties of carbon nanotube modified polymer materials. The tribological wear mechanism of polymers and the influence of friction-reducing fillers on the tribological properties of polymers and the related lubrication mechanism explanation are outlined, and the factors influencing the tribological properties of composites by carbon nanotubes and the related lubrication mechanism explanation are analyzed. The presented review will be beneficial for the production of high-performance polymer nanocomposites.

PEEK is being used increasingly often in seals, bushings, bearings, and other moving parts due to its excellent mechanical and tribological properties. Herein, PEEK-based composites were prepared using PI as the organic filler and h-BN and nano-SiO2 particles as the inorganic fillers. There was significant improvement in the tribological properties of PEEK at conditions above the glass transition temperature; the coefficient of friction of +20P/4B/4Si was stabilized at 0.06 at 200 °C and the wear rate was reduced by 60% compared to PEEK. The role played by the thermal conductivity of h-BN and the promotion of friction transfer film by nano-SiO2 in improving the tribological properties of PEEK is illustrated. The modified composites exhibited stable mechanical and tribological properties over a wide temperature range, which is instructive for instrumentation and testing applications in harsh environments.
