Summary: The properties and tribological behaviors of a-C:H:Cu films with different copper contents in various simulated body fluids were studied. Copper incorporation resulted in declining wear resistance in deionized water, enhanced wear resistance in saline solution due to the graphitization of wear debris, and significantly improved wear resistance in BSA solution by improving protein adsorption capacity and facilitating the formation of denatured albumin with non-native beta-sheet structures.

Summary: Solid lubricants are attracting attention for their use in special working conditions, and MXenes have become popular due to their nanolaminated structure and weak interactions. The MXene-based films modified with polydopamine showed significantly enhanced tribological performance and load capacity, with Si-MX/PDA-HOAC performing the best. A lubricating protection film containing FeF2 formed on the silicon/steel surfaces played a key role in demonstrating excellent tribological properties in this study.

Summary: The experimental results show that under dry friction conditions, the texture structure has a significant impact on the friction coefficient and wear resistance of diamond coatings. For the same type of textures, the larger the texture surface area, the lower the friction coefficient. Elliptical textures can capture abrasive particles and reduce the friction coefficient of diamond coatings.

Summary: This research article explores the tribological behavior of a PTFE/bronze composite under different frequencies and loads in dry and lubricated sliding conditions. The results indicate that the material exhibits good friction behavior at low loads and frequencies, and lubrication can improve the wear rate of the composite. Additionally, under lubrication, the load and frequency are inversely proportional to friction coefficients.

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.
