“…The increased crystallinity of UHMWPE can benefit the nanocomposites less prone to the movement of molecular chains during the friction process. 39,40 The storage modulus and loss factor (tan δ) of UHMWPE/HNTs@TiO 2 nanocomposites obtained from the dynamical mechanical analysis are presented in Figure 5. In Figure 5A, the storage modulus of all the samples shows a decreasing trend as the temperature increases.…”

A hybrid of halloysite nanotubes decorated with titanium dioxide nanoparticles (HNTs@TiO2) was synthesized by the sol–gel method and then mixed with ultra‐high molecular polyethylene (UHMWPE) by melt compounding to enhance its wear resistance properties. The incorporation of HNTs@TiO2 increased the crystallinity as well as the hardness of UHMWPE nanocomposites, which benefited less prone to plastic deformation during the friction process. In addition, the UHMWPE/HNTs@TiO2 maintained a high ductility character with a slight decrease in tensile strength compared to pure UHMWPE. With the addition of 3 wt% HNTs@TiO2, the UHMWPE nanocomposite achieved a remarkably low friction coefficient of 0.073 and a reduced wear rate of 6.67 × 10−6 mm3/N·m. These values represented a 32.4% decrease in friction coefficient and a 43.9% decrease in wear rate compared to pure UHMWPE. The improvement in wear resistance was due to the dislodged TiO2 and HNTs had good synergistic rolling effects at the counterface. Furthermore, the wear scan morphology observation revealed that the transferred HNTs@TiO2‐based materials could help to improve the quality of the tribofilms, which alleviated the abrasive wear from the metallic counterpart. This work offers a feasible way to enhance the wear resistance of UHMWPE nanocomposite without sacrificing the high ductility for expanding its engineering applications.Highlights TiO2‐decorated halloysite nanotubes were synthesized by the sol–gel method. The addition of HNTs@TiO2 maintained the high ductility character of UHMWPE. The UHMWPE composite with 3 wt% HNTs@TiO2 had the best wear resistance.

In search to meet technological demands, material studies as well as techniques to process them have been increasing worldwide, thus seeking to unite lower processing costs, the best properties of the materials involved, reuse of resources and more sustainable means. Thus, the development of new materials, coatings and composites have stood out in the market. For this work, we fetch the development and characterization of polyamide 6 composite coatings with quasicrystalline AlCuFe fillers, recycled through the spin coating technique, since that little is known about the interaction between these two materials, which have excellent isolating properties, and little is observed about the use of this technique to produce coatings with metallic loads. The recycled AlCuFe quasicrystalline alloy was manufactured by conventional induction casting. Polyamide 6 coatings with quasicrystalline particles were developed with additions of 0, 1, 3 and 5 (% vol.) quasicrystal, via SpinCoating technique. Thermogravimetric analyses (TG), differential scanning calorimetry (CSD), average roughness (RA), contact angle, surface energy and scanning electron microscopy (SEM) were performed to characterize this material. Being observed an increase in the thermal stability of the composite, reduction in average roughness (Ra) and surface energy values, with increase in quasicrystal fraction in the polymer matrix. In addition to hydrophobicity and oleophilic character of the samples with the addition of quasicrystalline loads. It can be concluded, in general, that the Spin Coating technique is effective in the production of polyamide composite coatings 6 with recycled quasicrystals, presenting interesting surface properties with potential for further studies in innovative applications, such as semiconductors and surface coatings.

“…Fluoropolymers reinforced with QC was also reported in several papers. 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.…”

“…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 ].…”

Antifriction hybrid fluorinated ethylene propylene-based composites filled with quasicrystalline Al73Cu11Cr16 powder, polytetrafluoroethylene, synthetic graphite and carbon black were elaborated and investigated. Composite samples were formed by high-energy ball milling of initial powders mixture with subsequent consolidation by injection molding. Thermal, mechanical, and tribological properties of the obtained composites were studied. It was found that composite containing 5 wt.% of Al73Cu11Cr16 quasicrystals and 2 wt.% of nanosized polytetrafluoroethylene has 50 times better wear resistance and a 1.5 times lower coefficient of dry friction comparing with unfilled fluorinated ethylene propylene. Addition of 15 wt.% of synthetic graphite to the above mentioned composition allows to achieve an increase in thermal conductivity in 2.5 times comparing with unfilled fluorinated ethylene propylene, at that this composite kept excellent tribological properties.
