“…It shows that the abrasive particle size (B) has the most substantial effect on wear rate with the contribution of 39.78% followed by the applied load (A) that has an almost similar contribution to that of particle size (33.10%) and 1/(se) (19.40%). It confirms the previous studies by other researchers that the wear rate depends more on the abrasive particle size than that of the normal load for different materials . In comparison to the total contribution of the main factors (92.28%), the contribution of interaction effects is negligible.…”

“…Besides that, elastomers have unique physical and mechanical properties, for example, high specific strength, Poisson's ratio, and enormous elongation at break. They are widely used in automotive components, conveyor belts, sealing material in hydraulic systems, pneumatic systems, compressors, agriculture, slurry pump sacrificial parts, internal combustion engines, mining, chute liners, and other associated fields, where the wear behavior in nonlubricated contacts is a vital factor for material selection . The service life of components in a system is limited because of friction and wear, which are unavoidable.…”

“…The service life of components in a system is limited because of friction and wear, which are unavoidable. When two surfaces are in relative motion under a certain pressure, abrasive wear is the main failure mechanism defined as a displacement of materials from the surface because of the protuberance of the hard abrasive particles …”

“…In practice, friction and wear are the results of many interactions caused by asperities distributed on the opposing counterface. Depending on the geometry of asperity (such as shape and size) and external loading, material removal's rate changes, and its mechanism might be abrasion by ploughing or microcutting that eventually affect friction, surface topography, and surface roughness of the material, which is an important indicator of the wear mechanism. The temperature rise in interfaces also needs to be considered in relation to abradibility.…”

“…The tribological behavior of materials is affected by operating variables such as applied load, sliding distance, abrasives, and counterpart texture. It is reported that the wear rate increases with the rise of abrasive particle size and applied load . For instance, according to Archard, the volume of the worn material depends linearly on the applied load, sliding distance, angle of irregularity slope, and the hardness of relatively softer materials in contact.…”

This study investigates the wear, surface roughness, and temperature buildup (TBU) of styrene butadiene rubber (SBR), natural rubber (NR), and nitrile butadiene rubber (NBR) while sliding over abrasives of different sizes with the variation of normal load. Rubber properties such as tensile strength (s) and elongation at break (e) were considered as input parameters. Individual, as well as interacting effects of different parameters, were analyzed in‐depth by using statistical methods. Overall wear of rubber depends not only on the tribological system but also on mechanical properties that contribute different wear mechanisms in addition to abrasion. The abrasive particle size and 1/(se) are the first and second most significant contributing factors, respectively, to all output parameters except the wear rate where the second contributing factor is the applied load and abrasive size is the highest contributor. Larger abrasive particles deepen ploughing marks, which is enhanced by the higher load, and lead to higher surface roughness. The effect of load on TBU is negligible because of the soft nature of the rubber material.

Nitrile butadiene rubber (NBR) has received a lot of attention as a sealing material, and its tribological performance is a crucial factor in determining the efficiency with which it will operate under various operating situations. In this study, NBR specimens with varying degrees of cyanide content, namely low cyanide (DN401), medium cyanide (DN2850), medium‐high cyanide (DN3380), and high cyanide (DN4050), were selected to investigate their tribological behavior when subjected to NO.10 aviation oil. To emulate their frictional responses during startup and shutdown operations, all four types of NBR were assessed under dry conditions. As the cyanide content increased, the coefficient of friction (COF) dropped from 1.381 to 0.810 and wear rate dropped from 2.38 × 10−3 mm3/(N m) to 1.88 × 10−4 mm3/(N m). When employed in conjunction with NO.10 aviation oil, DN401 and DN3380 exhibited COFs of 0.0963 and a slightly higher value of 0.127, respectively. Following aging treatment at 80°C in NO.10 aviation oil, stress reduction reached 65.8%, indicating the poorest performance among the four variants of NBR. Considering the COF, wear rate, and aging performance, DN3380 emerges as the most favorable choice for practical applications, thereby offering valuable insights into the selection of nitrile rubber for sealing materials.

Curing, mechanical, and tribological properties of hydrogenated nitrile butadiene rubber reinforced with Al₂O₃ nanoparticles

A novel hydrogenated nitrile butadiene rubber (HNBR) composite filled with organically modified Al 2 O 3 nanoparticle was fabricated. The effects of nanoparticle Al 2 O 3 (nano-Al 2 O 3 ) with different particle sizes on the curing, mechanical, and tribological properties of the HNBR composites were studied.Nano-Al 2 O 3 with different particle sizes (i.e. 10, 50, 100, and 200 nm) was filled into the HNBR in this work. Attenuated total reflection Fourier transform infrared (ATR-FTIR) spectroscopy was used to investigate the degree of grafting between modified nano-Al 2 O 3 and rubber matrix. Universal material testing machine was used to study the mechanical properties of the HNBR composites. The tribological properties of the HNBR composites were tested by a ballon-on-disk tribometer. The wear morphology of the HNBR composite surface was examined by scanning electron microscopy (SEM). The test results reveal that the nano-Al 2 O 3 as filler of HNBR composite promoted the vulcanization process, improved tensile and compressive strength, and increased hysteresis energy density and the damping coefficient. And the mechanical properties of the HNBR composite improved gradually with the decrease of nano-Al 2 O 3 particle size. The friction and wear test results show that the addition of nano-Al 2 O 3 greatly reduced the dry friction coefficient and specific wear rate of HNBR composites, and the friction coefficient and wear rate decreased gradually with the decrease of nano-Al 2 O 3 size. The HNBR composite filled with 10 nm nano-Al 2 O 3 had the better mechanical properties and anti-wear performance due to that the 10 nm nano-Al 2 O 3 could form denser cross-linked network.
