Effect of a quasicrystalline filler on the tribological properties of a composite based on ultrahigh-molecular-weight polyethylene

Microstructural, Mechanical and Tribological Behaviors of Cu/LLDPE-Based Composite Coatings for Lightweight Applications

“…into a high-strength polymer matrix (PEEK, PPS, PI, etc. ), ensuring the formation of a high-wear-resistance transfer film on the counterpart, which preserves the strain-hardened properties of the neat polymer [6][7][8][9][10][11][12][13][14][15][16]. Among the various non-metallic and metallic solid lubricant fillers applied in thermoplastic composites, previous works have discussed the positive effects of incorporating a mass content of carbon-based materials not exceeding 10 wt.% to Polyamide 66 (PA66) or ultrahigh-molecular-weight polyethylene (UHMWPE) matrixes on the tribological properties of the composites [6,8].…”

Tribological, Mechanical and Thermal Properties of Fluorinated Ethylene Propylene Filled with Al-Cu-Cr Quasicrystals, Polytetrafluoroethylene, Synthetic Graphite and Carbon Black

“…A positive effect of high density polyethylene reinforcement with QC was observed in [ 18 ], where an increase in polymer wear resistance as a result of filling was accompanied with no abrasion of an aluminum counterface. Several investigations on QC-filled ultra-high molecular weight polyethylene were carried out [ 19 , 20 , 21 , 22 , 23 ]. Most of them confirm the positive effect of the QC reinforcement on the polymer frictional behavior; however, in [ 23 ] the chipping of QC particles from the polymer matrix was reported.…”

“…Several investigations on QC-filled ultra-high molecular weight polyethylene were carried out [ 19 , 20 , 21 , 22 , 23 ]. Most of them confirm the positive effect of the QC reinforcement on the polymer frictional behavior; however, in [ 23 ] the chipping of QC particles from the polymer matrix was reported. Such chipped particles cause abrasive wear of the studied composite and counterface, and a significant increase in the friction coefficient volume.…”

“…Polytetrafluoroethylene- [ 31 , 32 ] and ethylene-tetrafluoroethylene [ 33 ]-based composites reinforced with QC were investigated. It was noted [ 32 ] that in contrast to the ultra-high molecular weight polyethylene-based composites, tested under the same conditions [ 23 ], a positive effect of QC on the wear resistance of polytetrafluoroethylene and ethylene-tetrafluoroethylene-based composites was observed, which was associated with better QC adhesion to fluoropolymers than to polyethylenes. This indicates that fluoropolymers should be considered as suitable matrices for QC-filled composites.…”

“…It should be noted that in most of composites discussed above icosahedral QC alloys of a Al-Cu-Fe [ 13 , 15 , 17 , 19 , 20 , 21 , 23 , 24 , 29 , 30 , 31 , 32 , 33 , 34 ] system or of Al-Cu-Fe systems alloyed with boron [ 14 , 16 , 26 ] were used as reinforcing particles. Indeed, Al-Cu-Fe is the most investigated QC-forming system, as the icosahedral QC phase in this system is thermodynamically stable, easy to synthesize, and possesses a number of advanced properties [ 35 ].…”
