Summary: The study investigated the fundamental wear mechanisms of graphite under high mechanical load in sliding friction. Increasing the film thickness of graphite coatings led to a higher coefficient of friction due to ploughing effects, but also resulted in extended coating lifetime and reduced counterbody wear. By increasing substrate roughness, the performance in terms of friction, wear, and lifetime could be further improved.

Summary: The hardness and tribological properties of D6A and C75S spring steels implanted with nitrogen ions were studied. It was found that the implanted samples went through two stages of wear process, with low friction coefficient and wear rate in the first stage, and considerably increased values in the second stage. The duration of the first stage depended on the applied load, with extended wear life at low contact pressure.

Summary: This study investigated the tribological properties of an AlSi10Mg alloy fabricated using laser powder bed fusion in both as-built and T6-treated conditions. It was found that T6 treatment resulted in a loss of hardness, toughness, and strength, and had either no significant effect or was detrimental in dry sliding wear tests.

Summary: This study investigates the effect of interfacial reactions between Al and WS2 during composite production on tribological performance. The Al-WS2 fabricated at 580°C exhibited the lowest coefficient of friction and wear rate, while evidence suggests that a controlled amount of reaction products is beneficial for tribological properties.

Summary: The study investigated the sliding wear behavior of hybrid polymer nanocomposites under different loading conditions and counterface roughness. The synergistic effect between nanoparticles and micro-sized fillers on friction and wear performance depended on the tribological system involved. TiO2 nanoparticles are only beneficial when blended with other wear debris to reduce friction and wear.

Summary: Aluminium metal matrix composites were synthesized using a novel stirring device, and the effects of different matrix alloys, SiC particle fractions and sizes on the wear performance of the materials were investigated. Dry sliding pin-on-plate tests were conducted against a high-speed train brake pad to evaluate the wear performance, and electron microscopy was employed to study the wear surfaces. The formation of an iron-based tribolayer during wear provided protection to the metal matrix composite, and the composites with small SiC particles exhibited lower wear rate and friction coefficient compared to other composites.

Summary: This study utilized electrodes containing Fe(16-X)CrX(B,C)(4) alloys for surface alloying on steel substrates, resulting in alloyed layers with a composite structure containing a significant amount of carbides and borides phases. With increasing chromium content, the microstructure of the hardfacing layers transitioned from hypoeutectic to hypereutectic structure, leading to improved corrosion resistance in the coating layer.

Summary: It is well established that titanium and its alloys have poor tribological performance at high temperatures, especially for self-mated titanium-titanium pairs. Previous work has shown that incorporating a TiB2 ceramic lubricant can significantly improve the mechanical and high temperature tribological behavior of pure titanium. This current study explores the possibility of extending the lubrication temperature range of Ti-TiB2 composites through the addition of a Ni-Bi solid lubricant using laser melting. The study found that the self-lubricating Ni-Bi samples exhibited a unique microstructure featuring a hard B-rich phase inside a lubricous Bi-rich phase, resulting in a two-fold increase in surface hardness compared to the underlying substrate. Additionally, the Ni-Bi samples demonstrated a significant decrease in coefficient of friction and wear rate when sliding against a Ti-alloy counterbody at temperatures of 400°C and 600°C due to the formation of a self-lubricating tribo-oxide layer rich in Bi-compounds. These findings are compared to the unmodified reference Ti-TiB2 composite.

Summary: The wear properties of extruded Mg-Zn-Y alloys with a long-period stacking ordered (LPSO) phase were studied during lubricated pin-on-disc type tests. It was found that the presence of a fine plate-like LPSO phase inside the alpha-Mg grains has effects on wear mass loss and can delay dynamic crystallisation of alpha-Mg grains.

Summary: This study compared the wear performance of candidate replacement materials, Cr2O3 and Cr3C2-NiCr, with traditional HCP coating, revealing similar performance in different testing environments but with significant differences in deionised water and borated water, suggesting the merit of using borated water in future testing. Insights into wear mechanisms were provided through SEM and XPS data, including particle pull-out and tribolayer formation, with preferential removal of Cr3C2 observed in a borated water environment during wear testing.

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.

Summary: The influence of high-carbon addition on the microstructure, hardness, and wear behavior of CoCrNi alloy was investigated. It was found that the addition of carbon resulted in the formation of carbide particles, enhancing the hardness and improving the wear resistance. Fracture and detachment of hard carbides during friction introduced additional abrasive particles, transitioning the wear mechanism from adhesive-dominated to abrasive-dominated.

Summary: This study reports the tribological behavior of nanodiamond plate (NDPL) as a nanoadditive for the first time and compares it with nanodiamond particles (NDPA). The results show that NDPL provides better lubrication performance at higher concentrations, and the sliding between NDPLs and the structural transformation from sp3 to sp2 carbon play a crucial role in lubrication and wear resistance.
