“…Materials with self-lubricating abilities can minimize friction and wear by forming a protective lubricating coating on the surface. This film acts as a barrier, preventing direct contact between the surfaces undergoing friction [51]. This film acts as a heatreducing barrier during friction, resulting in decreased wear [52].…”

Additive manufacturing has witnessed an upward trend in utilization across diverse industries in recent years. This study examines the tribological properties of polymer composites produced using additive manufacturing. The polymer composites were produced using the fusion deposition modeling process. Subsequently, they undergo thermal spray coating and spin coating processes that deposit hafnium carbide particles onto their surface. The wear test studies were conducted at three distinct temperature levels in accordance with the ASTM standard procedure. The findings demonstrated that the application of a ceramic particle coating led to a substantial decrease in the specific wear rates. Additionally, there were observed differences in the wear rates depending on the specific methods used for applying the coating. The application of thermal coating shown high efficacy in reducing wear rates and safeguarding the underlying materials against material loss. The uncoated PLA-CF material showed a slightly significant amount of material degradation as the test chamber temperature increased, in comparison to the coated specimens. The average specific wear rate of the thermally coated PLA-CF specimen at a temperature of 70˚C is 0.000156 kg/Nm.

“…It causes repeated melting of the PEEK and increases the COF. The addition of PPTA reduces the peak COF of PPTA/PEEK composites during run-in wear because PPTA maintains good mechanical strength at high temperatures 15 . When the proportion of PPTA increased from 2wt% to 6wt%, the contact area between the bers and the friction pair gradually increased, and its enhancement effect was gradually manifested.…”

“…When 1.5wt% aramid bers were added to the glass bers fabric, the surface deformation of the composites was reduced, and the wear resistance properties were improved by 65%. Yu et al 15 researched the friction and wear performance of self-lubricating fabrics with cyclic aramid bers and PTFE bers under high-temperature conditions. The results show that PTFE composites containing cyclic aramid have good resistance to plastic deformation under high temperatures, and the hightemperature wear resistance properties of self-lubricating fabric composites are related to their mechanical properties under high temperatures.…”

To improve the friction and wear performance of polyetheretherketone (PEEK). In this paper, a low-friction PEEK-based composite with PEEK as the matrix material, polytetrafluoroethylene (PTFE) as the solid lubricant, and poly-p-phenylene-terephthamide (PPTA) as the reinforcing material were prepared by compression molding technique, and then the optimal preparation condition for PEEK was gained by exploratory experiments. Finally, the tribological performance of PTFE/PPTA/PEEK composites was researched under dry friction and oil lubrication conditions. The microstructure of the wear mark was observed by scanning electron microscope and white light interference microscope, and the wear mechanism of PEEK and its composites under different lubrication conditions were analyzed. The results show that the main wear mechanisms of the friction pair consisting of PTFE/PPTA/PEEK composites and bearing steel are ploughing and adhesive wear. When the friction pair slides, PPTA reduces the wear of the composite caused by its high fiber strength and good thermal stability, and the coefficient of friction (COF) is reduced because the PTFE on the surface is pressed into a smooth, solid lubricating film. Whether under dry friction or oil lubrication conditions, the PEEK composites containing 25wt% PTFE and 6wt% PPTA both have the lowest wear and lower COF.

“…The incorporation of 1.5 wt% aramid fibers into the glass fiber fabric significantly reduced surface deformation of the composites, leading to a 65% improvement in wear resistance properties. Yu et al [15] previously investigated the friction and wear properties of self-lubricating fabrics consisting of cyclic aramid and PTFE fibers under elevated temperatures, revealing that PTFE composites reinforced with cyclic aramid fibers displayed remarkable resistance to plastic deformation at high temperatures. The durability of these self-lubricating fabric composites against wear at high temperatures is related to their mechanical properties under such conditions.…”

This study introduces a low-friction composite based on PEEK to improve its friction and wear properties. The composite incorporates PTFE as a solid lubricant and utilizes PPTA as a reinforcing material within the PEEK matrix. These components were prepared utilizing a compression molding method, followed by a series of exploratory experiments to identify the optimal preparation conditions for PEEK. This research assesses how the PTFE/PPTA/PEEK composites perform in terms of friction and wear under dry and oil-lubricated conditions. By examining wear tracks using scanning electron microscopy and white light interference microscopy, this study aims to uncover the wear mechanisms of PEEK and its composites under different lubrication scenarios. Results show that the main wear mechanisms for the PTFE/PPTA/PEEK composites and bearing steel are ploughing and adhesive wear. The presence of PPTA helps reduce wear by leveraging its strong fibers and thermal stability, while the coefficient of friction decreases as PTFE creates a smooth, solid lubricating film on the surface. Notably, PEEK composites containing 25 wt% PTFE and 6 wt% PPTA demonstrate the lowest wear rates and reduced coefficient of friction in both dry and oil-lubricated conditions.
