“…At the center of the untreated specimen, two kinds of wear morphologies can be observed ( Figure 6 a). One is the parallel waves that are perpendicular to the sliding direction, which is known as the Schallamach-type wave (STW) [ 22 , 23 , 24 ]. Another wear morphology is the micro-scar with an ellipse-shaped contour (marked with the dotted lines).…”

Both the high temperature and particle environment at the downhole greatly aggravate the abrasive wear and shorten the service life of the fluororubber (FKM) seal seriously in drilling engineering. At present, there is less awareness of the tribological behavior of seals in such complex working conditions. In this work, the abrasive wear performance of the thermally degraded FKM seal was tested in the form of simulating the intrusion of abrasive particles into the interface. Results show that the wear of both rubber seals and metal counterparts is exacerbated. Through the analysis of the wear scar morphology and friction coefficient, it is revealed that more abrasive caves scatter on the surface due to the mechanical degradation of the FKM. These abrasion caves reduce the tendency of particles to escape from the caves and prolong the abrasive action. Furthermore, the abrasion cave alters the particle motion from sliding to rolling, which leads to more caves generated on the surface of the hard tribo-pair. These results enhance the understanding of the abrasive wear for FKM seals and hopefully contribute to the promotion of seals used in hot abrasive particle environments.

“…The effect of hysteresis is greater than the effect of adhesion on the friction coefficient. Zhang 15 reported that when rubber wear occurs, under either dry or wet wear conditions, the wear rate is proportional to the n th power of the applied frictional force. Hale et al 16 .…”

The stick–slip behavior and wear mechanism of ethylene–propylene diene monomer (EPDM) under various wear velocity conditions are investigated using a friction and wear testing machine. A change of wear velocity does not lead to the decomposition of the compounds and the formation of new compounds in EPDM. However, the friction coefficient tends to decrease with increasing wear velocity, but the noise intensity generated during the wear process tends to become stronger. In addition, the lag time tends to decrease as the wear velocity increases, but the rate of decrease in the lag time gradually slows down. Both adhesive wear and abrasive wear occur in the wear process of EPDM under different wear velocity conditions. Moreover, increasing the wear velocity leads to Schallamach waves on the EPDM wear morphology becoming larger. The results reveal the stick–slip behavior and tribological properties of EPDM under various wear velocity conditions. © 2022 Society of Industrial Chemistry.

In this work, the tribological properties of a new material obtained by revulcanization with styrene butadiene rubber (SBR) and devulcanized ground tire rubber (GTR) were investigated. GTR was devulcanized using the microwave method at a constant power while varying the microwave exposure time. Devulcanized rubber (DV-R) and untreated GTR were revulcanized by mixing with SBR at different rates (10, 30, 50 phr). To determine friction and wear characteristics of the samples, pin (ball) on disc and abrasion tests were conducted. Scanning electron microscopy (SEM) was employed to observe the worn surfaces of the composites to correlate the experimental test results to the wear mechanisms. All of these tests and experiments were performed on original vulcanized rubber samples for comparison. The composites exhibited different friction and wear behavior due to morphology, dispersion behavior and devulcanization functionalization of ground tire rubber. In general, DV-R/SBR composites exhibited improvement in both mechanical and tribological properties. However, the enhanced compatibility of DV-R resulting from the specific chemical coupling of DV-R with SBR was crucial for the mechanical, friction and wear properties.
