“…Abrasives enter between the components and result in abrasive wear that is generally the most costly form of wear (3,9). Understanding wear mechanism is useful by linking the abrasion resistance of rubber and its mechanical properties to predict product lifespan in service and to develop lab-scale abrasion test method accordingly (27,46).…”

“…In this case, abrasion of rubber is studied by using a needle that scratched the surface under controlled conditions (49). Rubber abrasion is explained as mechanical failure that forms periodic surface pattern termed as "abrasion pattern", which are also known as Schallamach wave after his name (46). 57is a relation between cyclic crack growth and stored energy release rate.…”

“…depicts material detachments and cutting on worn surface of EPDM(46). It is concluded that, with decrease of elastic modulus, type of abrasive wear mechanism changes from cutting to fatigue, and rubbers adhesion and tearing are most important type of abrasive wear(74).…”

“…Therefore, deformed molecular chains want to return to their original position and shape. However, because of rubber's visco-elastic nature, it does not return to the exact or original position(46). It forms initial stage of abrasive wear, and spread until reaching a constant pattern just like ripples in water.…”

“…SEM images of EPDM worn surface(46).Molnar et al (2) studied the effect of characteristics, morphological and mechanical properties of SBR rubber used in conveyor belt under two and three body abrasive wear. They reported that, three-body samples experience lower abrasion, which is caused by rolling and round particles.…”

Regular degradation of rubbers contribute frequent maintenance of conveyer belt system. This paper investigates wear rate and mechanisms of rubber and associated influential parameters based on the information available in literature. Abrasion, fatigue and roll formation are dominate wear mechanisms that are influenced by load, sliding velocity, hardness and friction. Correlations among influential parameters and their effect on rubber wear was established in details. Archad's equation does not work for rubber wear but researchers have proposed equations similar to that. Adhesion wear forms roll in the smooth surface when tear strength of rubber is low. Wear caused by adhesion is abrasion when surface texture is harsh. Hysteresis enhances fatigue wear if the substrate asperities are round or blunt.

In this work, octadecyl trichlorosilane (ODTS) was used to modify the surface of graphene oxide. Further, varied concentrations of silane‐modified graphene oxide were used to make silicone rubber nanocomposite. The mechanical, thermal, and tribological properties of the composite were studied. The results showed that a small amount of silane‐modified graphene oxide significantly increased the mechanical and tribological performances. Under dry sliding, silane‐modified graphene oxide to the silicone matrix significantly reduced wear and friction properties. Nanocomposites have a lower wear rate than neat silicone rubber; their friction coefficient is almost 36% less than pure silicone rubber: the higher the load and temperature conditions, the more significant the difference in friction and properties. Wear mechanisms were revealed by scanning electron micrographs of the worn surface. The transfer film formation on the counter surface and acceptable wear debris improved the nanocomposites friction and wear resistance characteristics.

Oxidative aging is a significant deterioration process that affects the performance and durability of rubber materials in various applications. Therefore, this study focuses on the development of new antioxidants‐based on polyaniline for ethylene propylene diene monomer (EPDM) rubber to enhance its resistance to oxidative aging. The novel polyanilines were prepared using in situ polymerization method and characterized using Fourier transforms infrared (FTIR) and thermogravimetric analysis (TGA). FTIR illustrates the success synthesis of polyanilines as it shows their characteristic functional groups. The thermal stability of the formed polyanilines is discussed through TGA and derivative of thermogravimetry (DTG) curves. The curves prove the good thermal stability of the synthesized polymers. The prepared polyaniline compounds were mixed to carbon black filled‐EPDM rubber composites using a roll mill and then vulcanized using sulfur curing process. Accelerated aging tests for the prepared EPDM rubber composites were conducted to evaluate the effectiveness of the antioxidants. Moreover, their impact on rheometer, mechanical, and swelling properties was studied. The results showed that the EPDM samples with the prepared polyaniline compounds exhibited improved oxidative properties compared to the EPDM sample with commercial antioxidant 2,2,4‐trimethyl‐1,2‐dihydroquinoline. These findings suggest that the novel antioxidants have the potential to enhance the durability and performance of EPDM rubber in various applications.
