Summary: With the addition of nanoscale lignin as a precursor, a core-shell microstructure was formed in silicon nitride ceramic, which refined the ceramic grains and improved the mechanical properties. The composite showed a lower friction coefficient and pin wear rate due to the formation of a surface layer containing graphene quantum dots and tribochemical products SiO2. This study prepared a high-performance green ceramic composite with potential applications in industries such as cutting tools.

Summary: The study found that enhancing aluminum matrix composites with size-tunable particles can improve their anti-wear properties. (TiB2-TiC)/Al-Cu-Mg composites with different particle contents and sizes were fabricated, and their microstructures, mechanical properties, tribology behaviors at elevated temperature, and wear mechanisms were investigated. The results showed that the micron-/nano-sized effect and mechanical mixture layer can weaken the influence of load on the composites, thereby better protecting the matrix and improving the wear resistance of the composites.

Summary: A new strategy for improving the high-temperature compressive strength and tribological properties of Al2O3/Cr2O3 composites is proposed. The study fabricates a three-dimensional continuous Al2O3 ceramic matrix with Cr2O3 particles and reveals the influencing mechanisms of composition and structure on the performance of the composites at high temperature. The composites show excellent tribological properties at high temperature due to the enrichment of Cr2O3 and the high load-carrying capacity of the continuous Al2O3 matrix.

Summary: The Sn/SiC and Sn/Zn composites were fabricated via a powder metallurgy route to strengthen pure tin and improve its dry sliding resistance. The hardening effect of Zn was found to be higher than that of SiC, with the former attributed to a direct load transfer mechanism. Pure tin was vulnerable to surface fatigue wear and plowing damage, while the wear mechanisms of the Sn/SiC composite and Babbitt alloy were controlled by subsurface crack propagation.

Summary: The tribological and electrochemical corrosion behaviors of copper matrix composites (CMCs) reinforced by different morphology of in-situ tungsten carbide were investigated in this study. It was found that the mesh-structured WC is more beneficial to the wear resistance of CMCs compared to granular and lumpy tungsten carbide. Despite its tendency to induce electrochemical corrosion, the novel findings provide a method to improve the wear resistance of CMCs.

Summary: In this study, the tribological properties of ceramic-based self-lubricating materials were investigated. The presence of multilayer graphene and 8-Si3N4 whisker was found to significantly reduce the coefficient of friction. The reduction was attributed to the comprehensive enhancement of mechanical properties and the presence of graphene lubricating film.

Summary: The study found that nickel-graphite self-lubricating composites are stable after oxidation at temperatures below 400 degrees Celsius for 300 hours, exhibiting self-lubrication properties, while high temperature oxidation can lead to increased friction coefficient and wear rate. Following oxidation at 600 degrees Celsius, a glaze layer forms, which, despite reducing the friction coefficient and wear rate, improves tribological properties without the presence of graphite lubricant.

Summary: The tribological properties of graphite/Cu composites with different graphite content were studied. The results showed that the friction coefficient and wear rate of 7 wt.% graphite/Cu composite were decreased compared with 5 wt.% graphite/Cu. However, both friction coefficient and wear rate increased with the graphite content exceeding 7 wt.%. The excellent tribological properties of the composites were mainly attributed to the synergistic action of the oxidative trib o-layer and graphite lubricant film.

Summary: The novelty of this study lies in constructing an Entropy-based wear and fluid-solid-thermal (FST) coupled model for journal bearings, and revealing the transient interaction behavior between wear evolution and FST evolution during repeated starting and stopping. The wear rate is measured experimentally, and the contact temperature, friction coefficient and normal contact force are obtained from the validated FST model. Wear tests and numerical calculations are conducted to validate the predicted wear rate and investigate the time-varying wear and FST evolution of journal bearings.

Summary: A polymer coating prepared by liquid spraying technology on the surface of 20CrMo steel demonstrates good tribological and anti-cavitation erosive properties. It can effectively replace CuPb24Sn copper alloy in valve plates for pumps under different lubrication conditions. The coating exhibits adhesive wear and reduces frictional loss, and mainly shows abrasive wear under complex working conditions. Its lipophilicity, high hardness to elastic modulus ratio, and corrosion resistance are the main influencing factors for its performance.

Summary: This study simulated the rolling contact of a driving wheelset over tangent and curved tracks at a speed up to 500 km/h using an explicit finite element approach to derive creep curves. The comparison between quasi-steady curves and transient curves in the presence of rail corrugation helped to identify cases where traditional theories are inapplicable and where transient effects must be considered. Additionally, the study further analyzed the influence of middle/high-frequency vibrations in the presence of rail corrugation.
