A comparative study on wear behavior and mechanism of styrene butadiene rubber under dry and wet conditions

Investigate on mechanical and tribological properties of solution styrene butadiene and butadiene rubber composites

“…In addition, the tribological behaviors of NR, SBR, and their blends rubber composites against fabric and cement counterface have been examined by Tangudom et al The rubber composites exhibited greater abrasive wear resistance against fabric counterface than cement counterface, and much wear loss of SBR composite has been found when against cement counterface under wet conditions. Furthermore, we have found that, in our previous study, the adhesion and hysteresis contribution to friction coefficient are different against marble block under dry and wet conditions. However, currently, the wear resistance of the rubber materials have been evaluated based on Akron, Taber, DIN abrasions, and so on; the silicon carbide and aluminum oxide are chosen as friction pairs; considerable fluctuation, noise pollution, and bad repeatability are coexisted in the testing process.…”

“…Under the low content of filler, because of the lower hardness of rubber composites and higher surface roughness of asphalt counterface, the penetration depth of the hard asperity into the rubber is increased. Based on adhesion and hysteresis theory of elastomer material, the hysteresis component plays a vital role in wear loss. As revealed in Figure (a‐e), the corresponding debris presents globular structure (Figure A‐E).…”

Functionalized graphene‐reinforced rubber composite: Mechanical and tribological behavior study

“…Figures and show abraded surface and corresponding debris for SSBR‐BR, SSBR‐BR‐GO, SSBR‐BR‐rGO, and SSBR‐BR‐FGS composites at low (500 g) and high loads (1000 g). A series of parallel ridges lying perpendicular to the friction direction and many grooves on the surface of abrade rubbers can be observed, which is similar to the worn surface of SBR samples in the previous study . For the SSBR‐BR‐FGS composites, the corresponding debris is adhered and more smaller.…”

“…For SSBR‐BR composite, the main mechanism is abrasive wear, which is caused by scraping and tearing of asperity of the counterpart . Furthermore, for filled SSBR‐BR composites, the existence of the layered graphene promotes to tear and peel off . In this case, adhesive and tear wear play an important role in wear rate, leading to the antiwear properties evidently decreased.…”

Effect of fretting wear on very high cycle bending fatigue behaviors of FV520B steel

“…These flake-shaped fragments may attach to the original surface (adhesion wear), or else be squashed into small parts under longitudinal contact pressure. The small debris cannot be discharged by vibration and eventually get trapped at the interface, which results in a three-body abrasive with a series of grooves parallel to the direction of sliding [31][32][33]. At the same time, the micro-cracks are initiated from micro-defects (voids, inclusions, dislocation pile ups, etc.)…”
