“…In polymer tribology, polymer blending is also an effective way to improve the tribological properties of polymers. A different kind of polymer blends has been studied by some researchers,1–7 and it is found that the friction and wear behaviors of polymer blends vary continuously with compositions, the friction coefficient and wear resistance of blends are superior to those of component polymers and reach optimum at certain compositions, although some reports are conflicting. Unfortunately, some related studies are very limited.…”

The mechanical and tribological properties of carbon fiber (CF) reinforced polyamide 66 (PA66)/polyphenylene sulfide (PPS) blend composite were studied in this article. It was found that CF reinforcement greatly increases the mechanical properties of PA66/PPS blend. The friction coefficient of the sample decreases with the increase of CF content. When CF content is lower (below 30%), the wear resistance is deteriorated by the addition of CF. However, the loading of higher than 30% CF significantly improves the tribological properties of the blend. The lowest friction coefficient (0.31) and the wear volume (1.05 mm 3 ) were obtained with the PA66/PPS blend containing 30% CF. The transfer film and the worn surface formed by sample during sliding were examined by scanning electron microscopy. The observations revealed that the friction coefficient of PA66/PPS/CF composite depends on the formation and development of a transfer film on the counterface. The abrasive wear caused by ruptured CFs (for lower CF content) and the load bearing ability of CFs (for higher CF content) are the major factors affecting the wear volume. In addition, the improvements of mechanical properties, thermal conductivity, and selflubrication of bulk CFs are also contributed to the wear behavior of PA66/PPS/CF composite.

“…It was reported that the friction coefficients of HDPE/PA6 polyblends were between that of HDPE and PA6, while the wear rates were higher than that of HDPE, sometimes even higher than that of PA6 [15]. The poor compatibility between HDPE and PA6 may be responsible for these results.…”

The effect of compatibilizer HDPE-g-MAH of different contents on the transfer and tribological behaviors of PA46/HDPE polyblends was investigated, using a ring-on-block wear tester. All the polyblends showed friction as low as HDPE of 0.20. The wear of the polyblends was reduced when the compatibilizer ranged from 1 to 5 wt.%, showing a minimum value as 1/7 of that of PA46 when the concentration of the compatibilizer was 5 wt.%. Scanning electronic microscopy (SEM) and Energy Dispersive Spectroscopy (EDS) analyses were used to examine the worn surface and the physical state of the acid-eroded transfer films on the counterface. It was found that the physical bonding between PA46 and HDPE phases became stronger due to the better compatibility of the polyblends. The strengthened physical bonding might decrease the peel-back process of the dispersed HDPE particles from the polyblend, enhance the adhesion between the transfer film and the counterface, and ultimately decreased the wear. The formation of a transfer film on the counterface was hardly detectable, which was the primary reason for the relatively high wear of the polyblend with excess compatibilizer.

“…Polymer blends are considered an alternative method to improve friction and wear behavior and also extend the range of polymer applications. The mechanical properties of high density polyethylene (HDPE) was increased by adding polyamide (PA6) to it while keeping its good frictional and wear resistance characteristics [11]. The addition of recycled polymers to pure ones can improve wear resistance and reduce friction.…”

Friction and wear of polymeric composites formed by blending polyethylene (PE) and polymethylmethacrylate (PMMA) filled with different metallic powders is discussed in the present work. The scratch test was carried out to investigate wear resistance and friction coefficient of the tested composites prepared by molding of polymeric blends. Wear was measured by the net area of the cross section of the groove caused by the scratch and friction coefficient was measured as the ratio between the tangential and normal force exerted during scratch process. The test results showed that the best blend was 25 % polyethylene and 75 % polymethylmethacrylate with addition of bronze caused significant decrease in friction and wear. Increasing cooling rate of polymeric composites increased plasticization and consequently wear decreased. The strong adhesion of silicon carbide and bronze in the polymeric matrix caused significant wear decrease.
