“…S7.8 †). This result is in partial agreement with the literature, 32,33,58 as other studies have reported a decreasing 1597 cm −1 band, attributing it to C]C stretching vibrations in aromatic rings. 29,59 Other notable changes in the irradiated samples were the increasing carbonyl peak at 1704 cm −1 wavenumber in all PU microplastics (Fig.…”

“…Overall, the results of the ATR-FTIR analysis aligned well with the scientific literature. 29,32,33,35,36,57–59 For all PU microplastics, yellowing via the quinonoid route was supported by the emergence of a band at 814 cm −1 (out-of-plane C–H bending vibration in 1,4-disubstituted aromatic rings) that had decreased by receiving a UV dose of 350 MJ m −2 , indicating that aromatic rings were degraded (Fig. S7.6†).…”

“…The three-dimensional confocal microscopy analysis also shows that the friction coefficient of the polyethylene inner lining tube (disc)-surface alloy coating (pin) friction pair is low, which is a typical low friction coefficient low wear rate pair. The three-dimensional confocal experiment shows that there are obvious furrows with small and uniform spacing under various loads [22][23][24].…”

This study conducted pin disc friction and wear performance tests on polyethylene-lined oil pipes and four types of centralizing materials (45# steel, nylon, polytetrafluoroethylene (PTFE), and surface alloy coating) in oil fields. The friction coefficient and wear rate were tested, and the wear mechanism was analyzed using scanning electron microscopy (SEM) and three-dimensional confocal microscopy. Using a combination of experimental testing analysis and theoretical research, a comprehensive evaluation of the current wellbore centering and anti-wear technology for oil was conducted. The experimental results indicate that the usage limit of polyethylene-lined oil pipes is 400 N, and compared to metal oil pipe materials, the wear rate of both stabilizing material and tubing material is lower, indicating that it has a certain service life. From the perspective of testing load, taking into account the factors of friction coefficient and wear rate, the recommended sequence of straightening material for polyethylene lined oil pipes is (1) surface alloy coating, (2) nylon, (3) PTFE, and (4) 45# steel.

“…The ball-cratering method belongs to the microscale abrasive wear tests commonly used to assess the rate of abrasive wear and the wear resistance of the various construction Materials 2023, 16, 4523 2 of 14 materials: metals [24][25][26], ceramics [27,28], polymers [29][30][31], thin coatings [32][33][34] and others [35]. Its accuracy and effectiveness has resulted in many modifications to investigate, for example, friction and wear processes simultaneously with performed tests [34,[36][37][38][39][40].…”

Wear-resistant steels are designed to allow for operation under extreme loading conditions. They combine large strength with resilience and resistance to abrasive wear. In stock, the steel is subjected to preliminary heat treatment. However, any further processing at temperatures higher than 200 °C results in tempering that influences the mechanical properties of the material. The presented paper aims to study changes in abrasive wear properties across the welded joint made out of this steel, and its prime novelty lies in using the ball-cratering method to test the wear resistance of the joints. To distinguish between different crystalline structures in the weld, metallographic and XRD analyses were performed that resulted in the determination of five primary zones for which wear tests were carried out. Abrasive wear rates, studied across the welded joint, indicate that the material in the HAZ has the lowest resistance to abrasive wear. Similarly, the obtained values of the wear index show decreasing resistance of the material approaching the joint axis.
