“…Wear and transfer of PTFE composite onto steel counterface were significantly reduced compared with non-lubricated conditions. 15 Since the same lubricant is usually used for the whole multi-component engineering system, the success of implementing polymeric parts to replace existing metal parts will partly depend on whether polymeric parts will be effective in lubricants designed for steel. While works like those in Table 1 have provided interesting insights on lubricated polymer-polymer or polymersteel contacts, information on roles of individual constituents in lubricants is lacking.…”

“…One of them was in sports car races over two seasons. [12][13][14] Among HPPs, polyetheretherketone (PEEK) [15][16] and polyamide-imide (PAI) [17][18] have been studied extensively for their tribological performance. Research so far has been focused on nonlubricated (dry) conditions, in which PEEK-steel and PAI-steel contacts at room temperature have friction coefficients in the range of 0.25-0.3 19 and 0.3-0.44 20 respectively.…”

“…High-performance polymers (HPPs) are polymers that exhibit desirable mechanical, and thermal properties even under harsh conditions. Polybenzimidazole (PBI) is a highly stable linear heterocyclic polymer characterised by its high strength, a low coefficient of thermal expansion, a thermal decomposition temperature greater than 500 °C, and broad chemical resistance [ 1 , 2 ]. However, there are issues with the processability of PBI products due to its high melt viscosity [ 3 ].…”

The blend of polyetheretherketone (PEEK) and polybenzimidazole (PBI) produces a high-performance blend (PPB) that is a potential replacement material in several industries due to its high temperature stability and desirable tribological properties. Understanding the nanoscale structure and interface of the two domains of the blend is critical for elucidating the origin of these desirable properties. Whilst achieving the physical characterisation of the domain structures is relatively uncomplicated, the elucidation of structures at the interface presents a significant experimental challenge. In this work, we combine atomic force microscopy (AFM) with an IR laser (AFM-IR) and thermal cantilever probes (nanoTA) to gain insights into the chemical heterogeneity and extent of mixing within the blend structure for the first time. The AFM-IR and nanoTA measurements show that domains in the blend are compositionally different from those of the pure PEEK and PBI polymers, with significant variations observed in a transition region several microns wide in proximity to domain boundary. This strongly points to physical mixing of the two components on a molecular scale at the interface. The versatility intrinsic to the combined methodology employed in this work provides nano- and microscale chemical information that can be used to understand the link between properties of different length scales across a wide range of materials.

“…High temperatures tend to facilitate the formation of transfer lms [34][35]. A robust transfer lm provides the low wear rate and steady coe cient of friction (COF) in a temperature range from 25°C to 300 °C [36]. This is because the increase in temperature is conducive to the occurrence of tribochemical reactions, as well as to the formation of transfer lms [37].…”

Polytetrafluoroethylene (PTFE), as one of the most widely used solid lubricating materials, is thought to be very efficient at forming transfer film because of terrific low intermolecular force. This work investigates the tribological properties of PTFE transfer film under dry friction, and further explores its formation process and evolution mechanism. The friction coefficient is the lowest when the transfer film thickness is in range of 8-12 μm. An evaluation method for transfer film is proposed. The results show that the quality of the transfer film is closely related to the test load and velocity. This method is expected to be a general evaluation method for polymer transfer film, which can further directly evaluate the wear state of polymers, and even directly predict the tribological properties of polymers and abrasion life.
