“…However, there is a clear difference in the variation of the The wear amount of the SS304 seal pairs under different loads is shown in Figure 7. Some studies have shown that an increase in pressure leads to an increase in metal wear [25], and the two curves showed similar trends. The total amount of mass loss was almost the same at the end of the tests.…”

Pressure has a significant effect on rubber seal performance in the abrasive environments of drilling. The micro-clastic rocks intruding into the seal interface are prone to fracture, which will change the wear process and mechanism, but this process is not yet known at present. To explore this issue, abrasive wear tests were carried out to compare the failure characteristics of the particles and the variation wear process under high/low pressures. The results show that non-round particles are prone to fracture under different pressures, resulting in different damage patterns and wear loss on the rubber surface. A single particle force model was established at the soft rubber–hard metal interface. Three typical breakage types of particles were analyzed, including ground, partially fractured, and crushed. At high load, more particles were crushed, while at low load, shear failure was more likely to occur at the edges of particles. These different particle fracture characteristics not only change the particle size, but also the state of motion and thus the subsequent friction and wear processes. Therefore, the tribological behavior and wear mechanism of abrasive wear are different at high pressure and low pressure. Higher pressure reduces the invasion of the abrasive particles, but also intensifies the tearing and wear of the rubber. However, no significant differences in damage were found for steel counterpart throughout the wear process under high/low load tests. These results are critical to understanding the abrasive wear of rubber seals in drilling engineering.

“…This decrease in COF was also due to the conversion of friction into the heat energy, in addition to providing the required energy for tearing and partial melting of the coating. In addition, the temperature rose due to friction, as reported, reducing the friction coefficient associated with lubricous chromium oxide layer formation [ 17 , 18 , 19 ].…”

The chromium nitride coating is a hard coating used to improve the sliding friction and wear behavior and is applied to engine components in various operating conditions even at an elevated temperature. In this study, chromium nitride was deposited by a physical vapor deposition process onto the cast iron substrate. All tribological tests were performed on linear reciprocating tribometer with a stroke length of 5 mm in a dry condition at variable temperature levels of 28 °C, 100 °C, 200 °C, and of 300 °C corresponding to loads of 10 N, 20 N, 30 N, and 40 N against the cylinder liner material. The worn surfaces of chromium nitride(CrN) coatings after friction tests were analyzed by scanning electron microscope (SEM) and energy-dispersive spectroscopy (EDS). The results showed that friction coefficients (COF) ranged from 0.93 to 0.34 from room temperature to 300 °C against the cylinder liner material as a counter-body of 6 mm in diameter; higher temperature results in the positive tribological performance of CrN, with at least 0.34 COF at 300 °C. The wear mechanisms of CrN and counter-body surfaces are abrasive wear accompanied by the slight oxidation. This study guides the wear behavior of cylinder liner coatings in an environment similar to the engine.

“…Hakami et al investigated the wear, surface roughness, and temperature increase of styrene-butadiene rubber, natural rubber, and nitrile-butadiene rubber when shifted over abrasive materials of various sizes, with normal load variation. The properties of rubber, such as tensile strength and elongation at break were regarded as input parameters [19]. In another paper, Hakami et al investigate rubber wear rate and mechanisms and the related affecting parameters based on the data published in the literature.…”

Conveyors are the means of transportation used in many industries. The load-bearing and tractive component of a belt conveyor is a conveyor belt which consists of a carcass and cover layers. During an operation, belts are exposed to loads that cause damage to the belts. It is therefore necessary to ensure that a conveyor belt possesses required mechanical properties during the transport of material. The key mechanical properties of a conveyor belt are tensile properties. They are significantly affected by the fabric carcass of a conveyor belt. The tensile properties of conveyor belts are largely affected by the carcass materials. They are also affected by the types of fibres in the longitudinal (warp) and transverse (weft) directions of the fabric carcass because the carcass transfers all tensile stresses of the conveyor belt. A fabric conveyor belt is regarded as a composite material, consisting of the carcass (polyamide P and polyamide-polyester EP) and the cover layers. The costs of a conveyor belt represent 10-30 % of the price of the entire conveyor. It is therefore reasonable to prefer only those conveyor belts that show the properties prescribed by relevant norms. The subject of the article is worn conveyor belts with renovated top cover (renovated conveyor belts). The tensile properties are used to assess the suitability for further use of renovated conveyor belts in practice. The article presents the analysis of tensile properties of renovated fabric conveyor belts in relation to the carcass type. The observed results were compared applying the DOE method, regression and correlation analysis, and the method of statistic induction. All the conclusions, made based on the above-listed methods, are identical for the examined tensile properties. The results indicate that the examined tensile properties of conveyor belts have not undergone any significant change after the renovation of the top cover layer.
