“…In comparison to the traditional multiphase fillers constituted by lubricating and enhancing agents, the self‐assembled hybrid had better dispersion and interfacial adhesion in the matrix. In our previous work 13 Nano‐MoS 2 capped PBO fiber was synthesized via an one‐pot hydrothermal method, and the experimental results showed that it had better comprehensive performance than the traditional two‐component packing (Figure 1), but influence of the grafting amount on the fiber surface was still not clear. Based on the above‐mentioned reasons, in this study, a series of hybrids containing the same amount of PBO fibers and different concentration of MoS 2 were synthesized and further be used to improve tribology property of the thermoplastic polyimide (TPI) matrix at high temperature.…”

“…Thus, in order to increase the extent of bonding of fibers and polymers, it is significant to modify the surface state of the fiber. These modification processes can be classified into “physics” and “chemistry” methods, “physics” methods include plasma treatment, 1‐3 corona discharge, 4 irradiation treatment 5,6 ; “chemistry” methods include acid etching, 7 coupling agent treatment 8‐10 and chemical grafting 11‐13 . In comparison to the traditional multiphase fillers constituted by lubricating and enhancing agents, the self‐assembled hybrid had better dispersion and interfacial adhesion in the matrix.…”

The self‐assembled hybrids were synthesized as a kind of filler with the function of reinforcing and lubricating, by which can improve its dispersion in the matrix, and enhance the interfacial adhesion with the matrix. However, the effect of the amount of grafting on the hybrid properties is still unclear. In this study, a series of antiwear hybrids with different grafting amount were synthesized and further be used to reinforce thermoplastic polyimide matrix. The method of comparative analysis had been applied to analyze the microstructural morphology, thermal property, mechanical property, and high temperature tribological behavior of these composites. The results indicated that with the increasing grafting amount of MoS2 on the PBO fiber surface in a certain range, the integrated performance of the composite increases.

“…However, using solid lubricant enhances the wear resistance without making the composite very brittle. Molybdenum disulfide is an excellent choice as reinforcement in composites due to its high thermal stability and lubricating property [36][37][38][39][40][41][42]. The presence of molybdenum disulfide resulted in reduction of wear debris and micro-cracks in the worn surface of aluminum 2219-molybdenum disulfide composite [40].…”

Aluminum matrix composites are widely used for making structural components in the aerospace and automobile industries. In order to sustain the operational demand, excellent anti-wear and corrosion resistance properties are required in the composites. To achieve this, molybdenum disulfide and cerium dioxide reinforced hybrid aluminum-based composites are fabricated by friction stir processing at different rotational speed and number of passes. Due to grain refinement and better particle distribution at high rotational speed and 2 pass, tensile strength and microhardness improves by sacrificing ductility. However, deterioration of mechanical properties than the as-received alloy is evident in all the composites due to dissolvement of strengthening precipitates. With increasing tool rotational speed, severe adhesion type of wear shifts to abrasion wear and the wear resistance also improves. All the composites show similar corrosion behavior as the unprocessed alloy. However, the corrosion parameters such as corrosion potential and corrosion current density were influenced by processing conditions. The composite produced with 1500 min À 1 and 2 pass exhibits highest wear and corrosion resistance.

“…[23][24][25][26] However, despite numerous beneficial properties, the application of PEEK for surface materials in friction and wear conditions is strongly limited because the decreased crystallinity and high COF during the friction process. 27 Accordingly, in recent years the researchers have focused on introducing some solid lubricants to reduce the COF of PEEK coatings, such as polytetrafluoroethylene (PTFE), 28 molybdenum disulfide (MoS 2 ), 29 and graphite 30 ). The PEEK-based composite materials exhibit good tribological properties during the friction process.…”

The lubricating failure problems caused by friction and wear severely inhibit the regular operation and lifetime of artificial implanted joints. In order to improve their wear resistance effectively, the functional nano/micro-composite coatings consisted of poly(ether-ether-ketone) (PEEK)/graphite/polytetrafluoroethylene (PTFE) were successfully prepared through electrophoretic deposition and heat treatment. Additionally, the friction and wear behaviors under different loads and lubricating mediums of the composite coatings were investigated systematically. The results show that the composite coating significantly increased the microhardness and wear resistance of PEEK coating. The introduction of graphite and PTFE fillers reduces the wear rates and coefficient of friction (COF) of the composite coating significantly. Especially under 10 N load conditions, the friction and wear tests show that the composite coatings drop by 80% of friction coefficient and an order of magnitude in wear rates compared to that of PEEK coating. The improved wear resistance can be attributed to the synergistic effect of PTFE and graphite fillers. As a result, the graphite provides good load-bearing capacity and the PTFE lubricant endow a low friction coefficient for the composite coatings. Thus, this study provides a better approach to improve the wear resistance of PEEK-based coatings.
