Summary: Surface topography plays a crucial role in tribological performance, affecting friction and wear differently based on roughness and orientation. The formation of super-lubricious DLC surface layer in DLC vs DLC contacts reduces friction significantly, although surfaces with roughness oriented at 45 degrees may lead to higher friction coefficients.

Summary: Considering tooth surface micro-morphology, a coupling analysis model for wear characteristics of involute gear under mixed lubrication was established. The mixture of squalane base oil and polyisoprene showed higher film thickness and lower coefficient of friction compared to polyalphaolefin oil and mineral oil. Increasing lubricant viscosity was found to reduce direct rough contact area and load ratios, thereby reducing wear.

Summary: This work investigates the impact of annealing conditions on tribolayer formation in copper under dry sliding conditions. It is found that annealing time leads to an increase in grain size, decrease in hardness, and increase in toughness and ductility. Friction coefficients decrease with longer annealing times, while surface damage is reduced. Wear is lower in softer material.

Summary: Elevated-temperature wear tests were conducted on AISI H13 steel at 400-600 degrees C under sliding speeds of 50 and 100 r/min. The wear behavior of H13 steel varied significantly depending on the sliding conditions, with the wear rate reaching the lowest at 500 degrees C and 50 r/min. The effect of sliding speed on wear behavior was attributed to the changes of tribo-oxide layers.

Summary: The wear behavior of 4145H drilling tool steel under real drilling fluid environment conditions was investigated using a modified test system. The wear mechanism of the steel depended on the hardness-to-abrasive hardness ratio. Polishing was dominant when a single soft abrasive was used, while a microcutting mechanism was observed when mixed abrasives were applied. The increase in mass fraction of hard abrasives significantly increased the wear rate of 4145H steel. Therefore, reducing the mass fraction of hard particles in the drilling fluid is important to extend the life of drilling tools and prevent downhole accidents.

Summary: The laser surface alloying of commercially pure copper with NiTi powder using a high-power diode laser improved corrosion and electrical wear resistances. The laser-alloyed samples showed higher corrosion potentials and lower corrosion current densities in simulated acid rain compared to pure copper. Additionally, their electrical wear resistances were enhanced due to the presence of pseudo-plasticity of B19' and hard IMPs, and work hardening effect during electrical wear.

Summary: Friction and wear affect the performance of wire rope and pose serious threats to its reliability. This paper investigates the tribological behavior of a transmission wire rope and examines its strength and fatigue performance under different surface wear conditions. The results reveal that the friction coefficient is influenced by rope structure, contact angle, and sliding velocity, while the wear characteristics mainly include spalling, furrows, and plastic deformation. The sliding velocity also affects the friction temperature rise. The study further demonstrates the impact of surface wear on breaking force, bending fatigue life, and crack propagation rate in the wire rope.

Summary: This paper presents a novel numerical methodology for calculating non-uniform residual stress distributions during the glass tempering process. The methodology considers the influence of local flow phenomena during thermal calculations and couples the unsteady and non-uniform heat transfer rate with the Narayanaswamy model to predict the non-homogeneous residual stress pattern. The obtained numerical results show good agreement with previous experimental investigations and the proposed methodology proves to be an efficient tool for understanding the underlying mechanisms and predicting the residual stress distributions during glass tempering.

Summary: Ablative laser processing with ultrashort pulsed laser beams can cause secondary emission of hazardous X-rays. However, the X-ray emission rates during ablative processing of biological tissue materials have not been widely explored. In this study, biological materials were ablated with ultrashort laser pulses and in-situ X-ray dose rate measurements were performed. The results showed the secondary emission of laser-induced X-rays in all the studied biological materials.

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.

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.
