“…The tribosurface analysis of PEEK-10%Ti 3 AlC 2 (Figure 13), PEEK-10%Cr 2 AlC (Figure 14), and PEEK-10%MoAlB ( Figure 15) and stainless steel showed similar behavior where triboxide based transfer film was observed on MAX or MoAlB surface. Different types of additives like Graphene, h-BN, glass fiber, ZrO 2 , SiC, SiO 2 , mica, WS 2 , CNT nanoparticles, Al 2 O 3 , and AlN [22][23][24][25][26][27][28][29][30][31][32][33][34] are added to the PEEK matrix to enhance the triboactive behavior of composites. From comparison perspective, it is important to note that tribological testing are done under different conditions for targeted application(s).…”

We report the synthesis and characterization of PEEK-MAX (Ti 3 SiC 2 , Ti 3 AlC 2 , and Cr 2 AlC), and PEEK-MoAlB composites by hot-pressing. Detailed microstructure analysis by scanning electron microscopy showed that Ti 3 SiC 2 particles are well dispersed in the PEEK matrix after the addition of 5 vol% Ti 3 SiC 2 but at higher concentration (≥10 vol%), the Ti 3 SiC 2 particles segregated at the phase boundaries and formed interpenetrating micro-networks. PEEK-Ti 3 AlC 2 and PEEK-MoAlB composites also showed similar structuring at the microstructural level. PEEK-Cr 2 AlC composites showed a different behavior where Cr 2 AlC particles were well dispersed in the PEEK matrix. All the three PEEK-MAX composites have lower hardness than PEEK-MoAlB composites as MoAlB particulates are appreciably harder than MAX phases but were harder than PEEK. Due to heterogenous nucleation, the addition of MAX phases or MoAlB reduced the crystallization temperature (T c) by a few o C. The formation of imperfect crystals also resulted in the lowering of melting point (T m) of these composites. PEEK reinforced with 10 vol% Ti 3 SiC 2 , Ti 3 AlC 2 and MoAlB showed plastic failure, and had higher strength than PEEK. Comparatively, PEEK reinforced with 10 vol% Cr 2 AlC did not show any enhancement. All the PEEK-MAX and PEEK-MoAlB composites showed triboactive behavior and enhanced wear resistance.

“…In recent years, it has been widely used in a variety of structural and insulation applications in different environments, including moisture, due to its high chemical stability, excellent mechanical resistance, self-lubricating properties and wear resistance to elevated temperatures up to 260°C (Ref [2][3][4]. PEEK is also often used as a composite coating matrix material for tribological applications (Ref [5][6][7][8][9][10][11][12][13][14][15]. Some of the possible applications of PEEK-based composites are slide bearings, gears and piston rings under various loading conditions (Ref 4,16).…”

“…Thus, in addition to the polymer structure, further enhancement of mechanical and tribological performance of PEEK coatings is possible via incorporation with inorganic fillers. According to the available literature, the PEEK matrix has been filled with different particles, such as BG, HA for medical applications (Ref [22][23][24] and Al 2 O 3 , SiO 2 , SiC, Si 3 N 4 , h-BN, ZrO 2 for mechanical engineering applications ( Ref 3,[5][6][7][8][14][15][16]. One of the most important inorganic fillers used to increase the wear resistance and load-bearing capacity of PEEK is Al 2 O 3 (Ref 3,14,16).…”

This paper describes ways of improving the tribological properties of the Ti-6Al-4V titanium alloy at room and elevated temperatures by electrophoretic deposition of Al 2 O 3 /PEEK708 composite coatings and postheat treatment. The microstructure of the coating components and the coatings was examined by scanning and transmission electron microscopy as well as x-ray diffractometry. The influence of cooling rate after heating of the coated alloy on the PEEK structure and coating surface topography was investigated. It was found that slow cooling with a furnace produced a semi-crystalline structure, whereas fast cooling in water generated an amorphous polymer structure. The semi-crystalline coatings exhibited a more developed surface topography than the amorphous ones. The coatings with a semi-crystalline structure revealed higher scratch resistance than the amorphous ones. The corrosion resistance of the uncoated and coated specimens was examined using electrochemical techniques in a 3.5 wt.% NaCl aqueous solution. Both coatings increased the corrosion resistance of the alloy. The friction and wear properties of the coated specimens against an alumina ball in dry sliding contact at room temperature and elevated temperatures of 150 and 260°C at ball-on-disk were examined. Both amorphous and semi-crystalline coatings increased the wear resistance and decreased the friction coefficient of the titanium alloy at room temperature. In addition, the semi-crystalline coating was also very effective in improving the titanium alloyÕs tribological properties at elevated temperatures. The obtained results clearly show that the composite alumina/PEEK coatings are promising for tribological applications in mechanical engineering.

“…Besides, comprehensive studies on the tribological properties of several typical ZnO particles (disk‐like, rod‐like, and nanoparticles) are rarely reported. In fact, sizes and morphologies of fillers are two dominant factors to determine the ultimate tribological properties of polymer‐based materials . Tiny morphology differences in a micro scale may bring a great number of discrepancies to material performances in a macro level.…”

In this paper, different morphologies ZnO (disk‐like, rod‐like, and nanoparticles) were introduced into phenolic composite coatings to comparatively investigate the tribological properties. The structural and morphological characterization was conducted with Raman spectroscopy, X‐ray diffraction, and scanning electron microscopy. The tribological performances of composite coatings were evaluated using ring‐on‐block tester under dry condition at room temperature. Experimental results indicated that composite coatings filled with 1 wt% ZnO micro‐disks possessed the optimal tribological performances. It was attributed to the strong interfacial interaction between ZnO micro‐disks and phenolic matrix induced by their specific polar structure. Moreover, different loads and sliding speeds were employed to further evaluate the tribological performances of ZnO micro‐disks/phenolic composite coatings. The outcome revealed that ZnO micro‐disks were potential anti‐wear fillers under harsh condition.
