“…The enhanced anti-wear performance by g-C 3 N 4 can be attributed to the high load-bearing capacity and mechanical properties [45]. It is generally believed that transfer films are closely related to the anti-wear performance of polymer/steel tribo-systems [46]. Generally, homogeneous transfer and smooth transfer films are good for high wear resistance owing to the prevention of direct contact between frictional surfaces [47,48].…”

Two-dimensional (2D) lamellar materials have unique molecular structures and mechanical properties, among which molybdenum disulfide (MoS 2) and graphitic carbon nitride (g-C 3 N 4) with different interaction forces served as reinforcing phase for polytetrafluoroethylene (PTFE) composites in the present study. Thermal stability, tribological and thermomechanical properties of composites were comprehensively investigated. It was demonstrated that g-C 3 N 4 improved elastic deformation resistance and thermal degradation characteristics. The addition of g-C 3 N 4 significantly enhanced anti-wear performance under different loads and speeds. The results indicated that PTFE composites reinforced by g-C 3 N 4 were provided with better properties because the bonding strength of g-C 3 N 4 derived from hydrogen bonds (H-bonds) was stronger than that of MoS 2 with van der Waals force. Consequently, g-C 3 N 4 exhibited better thermomechanical and tribological properties. The result of this work is expected to provide a new kind of functional filler for enhancing the tribological properties of polymer composites.

“…Filling modification is a simple and effective way to enhance the wear resistance of UHMWPE plate. The fillers used in wear resistance modification include particles and micro‐fibers that usually show higher hardness than UHMWPE (such as cubic BN, 5 Si 3 N 4 , B 4 C, SiC, 6 AlN 7,8 or carbon fiber 9,10 ) or excellent lubrication (such as graphite, MoS 2, 11 polytetrafluoroethylene, 12 or montmorillonite 13 ). The wear resistance strengthening mechanism of UHMWPE filling modification mainly lies in improving the hardness of UHMWPE or easy constructing a continuous transfer film and decreasing the coefficient of friction in the process of friction 14 …”

A simple and feasible method to enhance the wear resistance of ultra-high molecular weight polyethylene (UHMWPE) fibers was reported. The graphite oxide (GO) prepared using improved Hummer's method was surface modified with hexadecylamine to improve its compatibility with UHMWPE. Combined with well-dispersion of modified-GO (m-GO) in dichloromethane and the fact that the viscosity of UHMWPE suspension can be decreased by dichloromethane, the well dispersed m-GO/dichloromethane was added into UHMWPE suspension to improve m-GO dispersion in UHMWPE fibers. Finally, UHMWPE fibers with different m-GO concentration were prepared using gel spinning technology. The effect of m-GO concentration on the structure and properties of modified UHMWPE fibers were investigated. The results indicated that the melting temperature and crystallinity of m-GO modified UHMWPE fibers increased with increasing of m-GO concentration, while the fiber's crystal sizes and orientation increased, thus the tensile strength of m-GO modified UHMWPE fibers remained almost undamaged. The introduction of m-GO is beneficial to the formation of smooth transfer film on fiber's surface, which enhanced the self-lubrication of UHMWPE fibers. Compared with pure UHMWPE fiber, the UHMWPE fiber containing 1.5 wt% m-GO had enhanced wear resistance by 55.4% and still maintained high tensile strength of 29.98 cN dtex −1 .

“…Hence the pressure between components will increase that even lead to seizure. Specifically, fretting will both cause the occlusion or looseness of machine elements and accelerate the initiation and propagation of cracks, thus reducing the useful life of components and affecting the safety of the whole system (Pan et al , 2009; Wang et al , 2016).…”

Purpose The purpose of this study is to examine the fretting wear property of ultra-high molecular weight polyethylene (UHMWPE)-based composites reinforced by different content of attapulgite. Design/methodology/approach A series of composites were prepared by a hot-pressing method. Fretting tests were carried out using an SRV-IV oscillating reciprocating friction wear tester with a load of 10 N and a frequency of 100 Hz. The morphology of the fracture structure and the worn surface was observed by field-emission scanning electron microscopy, X-ray diffraction and a non-contact three dimensional surface profiler. Findings With the addition of attapulgite, the microstructure of the composites become more regular, and their heat resistance improved. Furthermore, the friction coefficient and the specific wear rate of the composites with lower filler content reduced compared with that of neat UHMWPE, and the optimum filler content is 1 per cent. Originality/value The study investigated the fretting resistance mechanism of the attapulgite in the UHMWPE matrix. The results could help to provide some experimental evidence for the broader application of silicates on the fretting wear resistance of polymers.
