“…During the past decades, different additives, except the modification of surface properties [21][22][23][24][25][26][27][28][29][30], were added into PEEK or PI to improve tribological properties. Many researchers conducted various experiments to investigate the friction coefficient and wear rate of various conditions, providing comprehensive mechanisms of friction and wear at different conditions.…”

Polyether-ether-ketone (PEEK) and polyimide (PI) are two kinds of engineering polymer materials widely used as roller bearing cages and rings under extreme environment because of their noise reduction and corrosion resistance properties. The Si 3 N 4 ceramic is the most common ball bearing material. Many current engineering applications of ball bearings require aqueous lubrication. Therefore, this study presents the aqueous lubrication of tribopairs formed by PEEK and PI material sliding against Si 3 N 4 ceramic. Experimental results show that two tribopairs exhibited the similar tribological properties under the dry condition. Water as a lubricant for the PI-Si 3 N 4 tribopair pairs effectively reduces both friction coefficients by 35.5% and wear rates by 32%. The water absorption of PI induces better tribological properties by changing the tribopair surface properties. In addition, the dimples appearing on the PI tribopair surface under water generate additional hydrodynamic lubrication and further improve the friction properties of surface. The PEEK-Si 3 N 4 tribopair shows similar friction coefficients under two kinds of environments. The wear rates under water are approximately more than two times of that under dry sliding. However, water inhibits the appearance of the crush phenomenon and enhances the carrying capacity of the tribopair. Energy dispersive spectroscopy and X-ray diffraction spectra demonstrate no chemical corrosion. The 3D profiler and SEM morphologies illustrate that the transfer film would be formed from the surface of PEEK under water but hindered under dry friction. Overall, the PI-Si 3 N 4 tribopair exhibits better properties than PEEK under water and is promising for future applications in the bearing industry.

“…Additionally, PEEK is very often regarded as the base for composites creation, while implemented to it elements (such as carbon powder, carbon fibers, glass fibers, and nano‐tubes) improve its both mechanical properties and wear resistance. Properties of the PEEK top layer can be changed through chemical modifications, plasma‐chemical as well as ions implantations . Chemical modifications of the PEEK surface are usually based on the sulfonation of sulfuric acid .…”

Diamond like carbon coatings were manufactured by dual frequency plasma enhanced chemical vapour deposition method on a poly(ether‐ether‐ketone) substrates. In the presented work, modified surfaces were characterized in terms of the tribological parameters, surface topography, mechanical properties and the chemical composition. Obtained results of the research indicate that the highest resistance against wear, which means the most probable application abilities, presented the carbon coatings created in RF plasma with the use of nitrogen for the preliminary stage of preparation. Due to that modification, it was possible to limit the coefficient of friction from the value of c.a. 0.4–0.26 and 35 times decrease the specific wear rate. The DLC coatings deposited in RF plasma exhibited hardness of about 2 GPa with a relatively low contribution of sp3 phase and surface roughness.
