“…Tang et al [9] reported that the sliding velocity played a significant role on the tribological characteristics of carbon fiber-reinforced PEEK. Xie et al [10] demonstrated that the incorporation of PTW into PEEK would achieve high-wear resistance and low-friction coefficient under low load.…”

The tribological behavior of poly(ether ether ketone) (PEEK) composites was investigated using a universal micro-tribotester under dry friction conditions. We studied the effect of addition concentration, applied load, and sliding speed on the friction and wear behavior of composites filled with multi-walled carbon nanotubes (MWNTs), graphene oxide (GO) nanosheets, and c-aminopropyl trimethoxysilane-modified graphene oxide (GO-Si) nanosheets. The results showed that the friction reduction and anti-wear performance of PEEK composites filled with GO-Si is the most effective, that of the composites filled with GO is the next, while that of the composites filled with MWNTs is the worst. GO-Si-filled PEEK nanocomposites have the best friction reduction and anti-wear properties when the applied load and the sliding speed are 2.94 N and 0.0628 ms -1 , respectively. Furthermore, scanning electron microscope (SEM) investigation showed that GO-Si-filled PEEK composites had smooth worn surface under given applied load and sliding speed, and well-dispersed GO-Si in PEEK matrix provided a large surface area available for interaction between polymer molecules and GO-Si, which helped to reduce the wear of PEEK composites.

“…Chen et al [8] investigated the friction and wear behaviors of PEEK/PEI/PES alloys under dry sliding contact condition and reported that wear resistance of the alloys were considerably higher than those of pure polyetherimide (PEI) and polyarylethersulfone (PES). Tang et al [9] researched on the tribological characteristics of carbon fiber-reinforced polyetheretherketone (CFRPEEK) sliding on Si 3 N 4 lubricated with water and determined that the sliding velocity has a higher effect on friction than pressure does. Rasheva et al [10] reported that fiber orientation influences the mechanical performance and tribological properties of short-carbon fiber-reinforced PEEK materials.…”

Abstract:The combined effect of the use of carbon fiber and seawater and the molecular structure on the tribological behavior of various polymer materials under natural seawater lubrication was investigated. After the investigation, the wear morphology of the contact surface was observed by a laser scanning confocal microscope, and the texture of the wear scars and tracks were presented in 3D profiles. Moreover, the mechanism of mixed lubrication and wear resistance was analyzed. The results demonstrated that the friction coefficient of carbon fiber-reinforced polyetheretherketone (CFRPEEK) is the lowest and fluctuates at approximately 0.11. Moreover, the seven polymer materials in ascending order of friction coefficients are CFRPEEK, carbon fiber-reinforced polyamide-imide, polytetrafluoroethylene, polyoxymethylene, polyetheretherketone (PEEK), acrylonitrile butadiene styrene resin, and glass fiber-epoxy resin. More critically, the simultaneous incorporation of deposition, polymeric scrap, hydrophilic groups, and seawater resulted in a decrease in the friction and wear of polymer materials under seawater lubrication. This observation implies that a synergistic friction-reducing and wear-resistant effect exists between carbon fiber, seawater, and the molecular structure of PEEK. As a result, a highly effective polymer material was discovered, CFRPEEK, which has the lowest friction coefficient of 0.11 and lowest wear rate of 2 × 10 -5 mm 3 ·(N·m) −1 among the polymer materials; this validates the selection of dual friction pairs for seawater hydraulic components.

“…Laboratory studies have shown that its friction and wear are critically dependent on applied load, sliding speed, environment, and counterface material [9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26]. In articulation against polyethylene (PE), low friction is typically observed for all ceramics, including various Si 3 N 4 compositions (i.e., <0.12) [27][28][29][30][31]; and even lower friction (i.e., <0.01) has been reported for Si 3 N 4 sliding against carbon-fiber reinforced polyetheretherketone (CRF-PEEK) [23]. For self-mated Si 3 N 4 , extremely low friction (≤0.002) and wear have been seen under well controlled, low-load, high-speed, and continuous motion devices; whereas high friction (>0.7) and accelerated wear are apparent for slow-speed, high-loads, and interrupted (stop-start) conditions [10].…”

Abstract:The articulation performance of silicon nitride against conventional and highly cross-linked polyethylene, as well as for self-mated silicon nitride bearings, was examined in a series of standard hip simulation studies. Wear rates for polyethylene liners against silicon nitride femoral heads were consistent with reported literature, although higher than cobalt chromium controls. Excessive protein precipitation was a confounding factor in interpretation of the wear data. Post wear-test Raman spectroscopy of the cross-linked polyethylene liners showed no oxidative degradation. Wear of self-mated silicon nitride was found to be essentially zero and indistinguishable from alumina controls using continuously orbital hip simulation for up to three million cycles. However, introduction of an alternative loading profile from three to five million cycles, including a stop-dwell-start sequence, significantly increased wear for two of six silicon nitride couples. This behavior is associated with formation and disruption of a gelatinous silicic acid tribochemical film, and is consistent with a recurrent transition from fluid-film to boundary lubrication. Overall, these results suggest that silicon nitride articulation against dissimilar counterface surfaces (e.g., highly cross-linked polyethylene) is preferred.
