Summary: The micro-texture of the CVD diamond coating affects the graphitization law and friction coefficient, with the order of concentric circles, hexagonal, and diamond shaped ribs decreasing the degree of graphitization. The degree of graphitization is positively correlated with the areal density of the micro-texture, and the depth of the texture has a weak positive effect. Graphitization of the textured surface can rapidly reduce and stabilize the friction coefficient, with the friction coefficient of the diamond coating decreasing with the increase of graphitization degree.

Summary: Differential-polishing design can enhance the skid-resistance durability of High-Friction Surface Treatment (HFST). The texture evolution and skid resistance of HFST prepared with different ratios of aggregates were analyzed under simulated traffic wear, and the generation mechanism of differential-polishing was investigated from the micro-view. The results show that differential polishing can effectively improve the skid-resistance durability of HFST by continuously constructing new texture structure, reducing wear loss and maintaining excellent surface roughness.

Summary: This study compared three newly developed polishing techniques, namely shear thickening polishing (STP), chemistry enhanced STP (C-STP), and electrolysis enhanced STP (E-STP). The results showed that C-STP produced a Beilby layer after polishing, resulting in improved mechanical and biological performance. C-STP had the lowest surface roughness and highest material removal rate (MRR) among the three techniques. E-STP showed intermittent improvements in surface roughness and MRR, and had the best wettability and corrosion resistance.

Summary: This study evaluates the skid resistance of runways by analyzing the microtexture and macrotexture of the surface. The research shows that aircraft operations have a significant impact on these characteristics. The results indicate that stone mastic asphalt concrete has better macrotexture compared to dense grade asphalt concrete. Aircraft landing operations reduce skid resistance, especially in terms of macrotexture. However, aircraft behavior at high-speed exits affects microtexture more than macrotexture.

Summary: If the arc length and intrinsic curvature of a curve or surface are kept constant, it is considered to be inextensible. Inextensible curve and surface flows are characterized by the absence of motion-induced strain energy. This paper studies inextensible tangential, normal, and binormal ruled surfaces generated by a curve with constant torsion, known as a Salkowski curve. It investigates whether these surfaces are minimal or developable and proves theorems related to inextensible ruled surfaces in three-dimensional Euclidean space.

Summary: This research analyzes the influence of different wire electrical discharge machining surface conditions combined with polishing treatment on friction and wear. The study found that the combination of finishing wire electrical discharge machining + polishing resulted in the highest friction coefficient, while roughing wire electrical discharge machining conditions led to the lowest friction coefficient. Scanning electron microscope images were used to describe wear tracks and pin degradation for different sliding abrasive configurations. The correlation between surface morphology and friction coefficient predicted wear damage on initial surface conditions, crucial for tool maintenance or replacement in the forging industry.

Summary: This study investigated the effect of in situ laser polishing on the surface modification of Ti-6Al-4V alloy fabricated by selective laser melting (SLM). The results showed that laser polishing significantly improved the surface quality of SLM parts by reducing surface roughness, decreasing the number of pores, increasing the depth of remelted layer, and enhancing microhardness and wear resistance. Furthermore, the reduction of microdefects and grain refinement led to stronger corrosion resistance. Therefore, in situ laser polishing is a suitable method for improving the surface properties of SLM parts and enables the integration of 3D printing and laser polishing.

Summary: The process of weathering affects the characteristics of geomaterials, causing aging and deterioration of aggregates structure. The primary chemical trend in natural weathering is the immediate loss of bases, although the rate of loss decreases with time. Weathering results in changes to the original textural features of andesitic aggregate materials, with clay minerals such as kaolinite and smectites forming as products.

Summary: This paper explores the factors that influence male and female engineers' intent to leave, and develops corresponding models. The findings show that an increase in access to career opportunities reduces intent to leave for both male and female engineers. Specifically for female engineers, being supported to bring their authentic selves to work and developing influential relationships decreases intent to leave. For male engineers, pursuing their ideas against the odds and being on the lookout for ways to improve one's life increases intent to leave.

Summary: This study investigates the impact of pedestrian assertiveness and vehicle user characteristics on driver yielding at mid-block sections. The findings suggest that yielding decreases with higher vehicle speeds and when vehicles are not part of a platoon. Pedestrians' hand gestures can increase drivers' willingness to yield, while pedestrians who run or cross heedlessly through traffic are less likely to influence driver behavior, especially in high-speed environments. Women are more likely to be given priority, especially when crossing at slower speeds.

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.
