Summary: Sliding wear experiments were performed to investigate the wear behavior and material removal mechanisms of Al-Al2O3 nanocermets. The results indicate that the wear behavior of nanocermets is a combination of abrasive and adhesive losses, and the milling duration has an impact on the wear resistance of the sintered nanocermets.

Summary: This study reveals the wear mechanisms of the abrasive wheel, including attrition wear, fracture and pulling-out of abrasive grains, material adhesion, clogging, and chemical wear. With the degradation of abrasive grain, the wear mode successively changes from attrition wear to grain fracture and pulling-out.

Summary: This study focused on the friction and wear process of fluoro rubber (FKM) seals against 304 stainless steel (SS304) after the introduction of SiO2 abrasives, discussing the influence of particle state changes on friction coefficient evolution, wear loss evolution, wear morphologies, and wear mechanisms. The results revealed that the presence of abrasive particles between the sealing interfaces improved the friction performance but deteriorated the wear performance of the metal counterpart, with the wear process divided into three stages based on particle movement and breakage. The main causes contributing to the change in wear mechanisms were the random movement and continuous breakdown of abrasive particles under abrasive wear conditions.

Summary: This study investigates the influence of variables such as load, velocity, humidity, slip ratio, and braking time on the emission of tyre wear particle matter (TWPM) generated by soft butadiene-styrene rubber tyres against concrete under braking conditions. The results show that the emission quantity of 3.0μm TWPM is much greater than that of larger TWPMs. Humidity and braking time have negative correlations with the quantity of 3.0μm TWPM, while load, velocity, and slip ratio have positive correlations. Abrasive rubber wear results in more severe TWPM emission than fatigue wear. The variables exhibit the following order of influence on the emission of 3.0μm TWPM: load, slip ratio, velocity, braking time, and humidity.

Summary: Three-body wear is a complex phenomenon that occurs when abrasive particles are present between two material surfaces. In this study, the wear between stainless steel and three different rubbers (TPU, NBR, and LSR) in a slurry environment was systematically investigated using a new experimental setup. The study found that wear on both metal and rubber pads increased exponentially with sliding speed, while the applied normal load had a weak correlation within the given range. It was also observed that the stainless steel experienced the most wear when in contact with NBR and the least wear when in contact with LSR. TPU rubber pads experienced the highest wear, while LSR pads showed minimal wear when in contact with stainless steel. Friction measurements indicated an inverse relationship between the system coefficient of friction and the amount of wear on the rubber elements. These findings suggest new directions for reducing three-body wear between metals and rubbers.

Summary: The study demonstrates the positive impact of corundum reinforcement on dry sliding wear behavior of LM30 aluminum alloy composites. The composites prepared by stir casting process exhibit uniform distribution of particles and refined microstructure, leading to improved hardness. The addition of corundum results in lower wear rate and coefficient of friction in the composites, and wear mechanism is pressure-dependent.

Summary: The discrete element method (DEM) can enhance the complexity of wear models, as demonstrated in this study by comparing laboratory results with DEM simulations. The sensitivity of particle parameters was evaluated, and the importance of using the progressive volume/shear work ratio parameter during simulation was confirmed through stress analyses.

Summary: The study investigated the influence of different axial loads on the tribological properties of HNBR in oil-based mud containing hard particles using experimental and theoretical methods. It was found that the tribological properties of HNBR vary with axial load and wear time, and the total friction coefficient can be separated into adhesion, hysteresis, and abrasive terms. The hysteresis term, caused by micro-strain on the HNBR surface and overall deformation, was identified as the main factor affecting the tribological properties.

Summary: In this study, a set of FCC-based medium-entropy alloys (MEAs) with varying carbon content were prepared and evaluated for their tribological performance. The results showed that increasing the carbon content not only improved the hardness of the alloy, but also reduced wear and minimized surface scraping and penetration.

Summary: Using an atomic force microscope, a nanoscale wear characterization method was applied to a commercial steel substrate AISI 52100, revealing two wear mechanisms: atom attrition and elastoplastic ploughing. The study found that the length-scale effect of the material's hardness property plays an integral role in the relationship between the 'degree of wear' and load.

Summary: A diamond abrasive grinding wheel was brazed using Ni-Cr-P-Si active powder filler alloys. The wear characteristics of the grinding wheel during dry cutting of ferrous metal and the interface between the diamond grains and steel substrate were investigated. Columnar-shaped carbides such as Cr7C3 and Cr3C2 were formed near the brazed interface. The study found that the diamond brazing abrasive wheel showed higher efficiency and safety compared to resin grinding wheel during cutting of ferrous metals.

Summary: The service performance of coated self-lubricating spherical plain bearings can be improved by applying self-lubricating coatings, especially double-sided coatings. The presence of a large-area and complete mixed friction transfer film on the contact surfaces can cause a signal downstage before the signal mutation stage.
