Abstract ：
This study presents a new surface strengthening technique (cold upsetting manufacturing process) for engine valve seating face (VSF). The properties of the Ni30 superalloy VSF were characterized before and after cold upsetting. Compared to the solution-aging treatment (SAT) valve, the solution-cold upsetting-aging treatment (SCUAT) valve hardness was increased by 60 HV0.2. SCUAT valves exhibited higher internal dislocation degrees and local misorientation than SAT valves. Bench-top wear tests at 650 degrees C and 750 degrees C were conducted. The valve wear loss at 650 degrees C was higher than that at 750 degrees C. SCUAT valves show better wear resistance, with a total wear loss reduction up to 26.76 %. The SCUAT valve-seat insert contact pair wear mechanisms are adhesive and fatigue wear.

Abstract ：
Superhydrophilic-underwater superoleophobic materials have received extensive attention in recent years due to their excellent performance in oil-water separation. However, they are still challenged by practical limitations. One of the main issues is the modification of traditional metal-based surfaces. These surfaces are typically modified through roughening and chemical treatment, but they still face significant challenges. Here, we report a metal rubber(MR) filtration material with exceptional superhydrophilic-underwater superoleophobic properties, fabricated through a synchronous process combining two-dimensional(2D) iron oxide sheets and zerodimensional(0D) silica nanospheres. This composite structure enhances surface wettability by integrating the dimensional effects of 2D and 0D components. This superwettable material, termed P-MRFS, incorporates a composite structure that enhances surface wettability by integrating the size effects of both 2D and 0D components. The P-MRFS material achieved a peak separation flux over 2500 L & sdot;m-2 & sdot;h-1 and up to 99.88% purity across various oil in water emulsions, including hexane, petroleum ether, dimethylbenzene, dichloroethane, and toluene, with a stable efficiency of 99.7% after 30 separation cycles. P-MRFS demonstrated durability under demanding conditions, maintaining over 99.5% separation efficiency after 48 hours in acidic, alkaline, and saline solutions and following 400 cm of abrasion under a 200 g load. Importantly, the study employed computational fluid dynamics(CFD) simulations to analyze the micro-scale mechanisms of emulsion separation, enabling realtime observation of droplet dynamics and revealing interactions within the multi-fiber structure that enhance separation efficiency. Overall, the P-MRFS material showed outstanding stability in corrosion and abrasion resistance, sustaining high emulsion separation performance even in complex environments. These findings suggest the material's high potential for future applications in oil-water separation, environmental protection, including crude oil recovery, and other industrial uses, underscoring its significant practical utility.

Abstract ：
Under severe work conditions, mechanical parts made of beryllium-copper alloy may undergo fatigue failure, which seriously affects the overall service life of the equipment. Therefore, improving the fatigue resistance of such kind of alloys is of great significance for their engineering application. In this research, C17200 beryllium-copper alloy was surface strengthened by means of a self-designed surface mechanical rolling treatment (SMRT) device. The fatigue behavior before and after SMRT was investigated using a ball-on-rod rolling contact fatigue (RCF) machine, and surface failure mechanisms were analyzed. It was found that the RCF resistance of the untreated C17200 alloy was weakened with the increase in the maximum Hertzian contact stress (sigma max). After surface treatment, C17200 alloy exhibited superior RCF resistance subjected to SMRT with a static rolling force of 200 N. But among the specimens treated by SMRT, the RCF resistance of beryllium-copper alloys was weakened with the increase in the SMRT static rolling force. The RCF life of specimens treated by SMRT with a force of 400 N is similar to that of untreated specimens, while the RCF lives of specimens treated by SMRT with a force of 735 and 980 N are even lower than that of untreated specimens. Thus, applying the appropriate static rolling force during SMRT can improve the surface quality and compressive residual stress, as well as enhance the fatigue resistance of C17200 alloys.

Abstract ：
In recent years, the application and fabrication technologies of superwetting materials in the field of oil-water separation have become a research hotspot, aiming to address challenges in marine oil spill response and oily wastewater treatment. Simultaneously, the fabrication technologies and related applications of superwetting materials have been increasingly diversified. This paper systematically reviews the sources and hazards of oily wastewater and oil-water emulsions, several traditional oil-water separation methods, and their limitations, thereby highlighting the advantages of superwetting materials. Additionally, this paper provides an overview of the fundamental theories of wetting and conducts a microanalysis of the penetration mechanism based on Laplace pressure at the gas-liquid-solid three-phase interface. Following this, the latest advances in superwetting oil-water separation materials are elucidated, focusing on five categories: (i) superhydrophobic-superoleophilic materials; (ii) superhydrophilic-underwater superoleophobic materials; (iii) superhydrophobic-superoleophobic materials; (iv) "special" superwetting materials; and (v) smart switchable superwetting materials. This paper innovatively discusses these materials from the perspectives of two-dimensional and three-dimensional materials, deeply studying the mechanisms of oil-water separation and using data to quantify the separation efficiency. Comparative discussions are conducted on the materials from various dimensions, including different substrates, innovations in existing technologies, and fabrication methods as discussed in various articles, followed by corresponding summaries. Finally, the existing shortcomings and challenges of current superwetting materials are summarized, and prospects are proposed. We firmly believe that developing low-cost, stable, environmentally friendly, and practical large-scale superwetting oil-water separation materials will have broad application prospects and potential in the future. Preparation methods of superwetting materials in different structural dimensions.

Abstract ：
Nickel-aluminum bronze alloys are prone to tool surface bonding and wear on the tool substrate during the cutting process. The correlation between tool surface bonding morphology, rear face wear, and cutting force is analyzed in terms of the dry turning method for cutting 9442-nickel-aluminum bronze. The rational cutting parameters and the mechanism of tool wear are further discussed. The results indicate that adhesion, oxidation, and abrasive wear occur on the tool surface during turning. At a turning length of 2000 m, tool wear increases with increasing cutting speed and feed. There is a tool wear difference of 2 to 3 mu m between adjacent cutting parameters, but the wear is similar at cutting speeds of 140 and 180 m/min. By appropriately reducing the cutting speed and feed rate, it is possible to promote the formation of an adhering layer on the rear face of the tool, thereby reducing overall tool wear. The best cutting results are achieved at a chip speed of 100 m/min and a feed rate of 0.05 mm/rev. However, at higher cutting speeds, there is susceptibility to the "bonding-flaking" phenomenon where material adheres to the tool surface, leading to fluctuations in cutting forces and accelerated tool wear. Higher feed rates result in increased cutting forces, which hinder the formation of an adhering layer on the rear face, causing severe wear on the tool matrix.

Copper particles emitted from braking have become a significant source of environmental pollution. However, copper plays a crucial role in resin-based braking materials. Developing high-performance braking materials without copper has become a significant challenge. In this paper, the resin-based braking materials were filled with fly-ash cenospheres to develop copper-free braking materials. The effects of fly-ash cenospheres on the physical properties, mechanical and friction and wear properties of braking materials were studied. Furthermore, the wear mechanism of copper-free resin-based braking materials filled with fly-ash cenospheres was discussed. The results indicate that the inclusion of fly-ash cenospheres in the braking materials improved their thermal stability, hardness and impact strength, reduced their density, effectively increased the friction coefficient at medium and high temperatures, and enhanced the heat-fade resistance of the braking materials. The inclusion of fly-ash cenospheres contributed to the formation of surface friction film during the friction process of the braking materials, and facilitated the transition of form from abrasive wear to adhesive wear. At 100-350 celcius, the friction coefficient of the optimal formulation is in the range of 0.57-0.61, and the wear rate is in the range (0.29-0.65) x 10-7 cm3 center dot N-1 center dot m-1, demonstrating excellent resistance to heat-fade and stability in friction coefficient. This research proposes the use of fly-ash cenospheres as a substitute for environmentally harmful and expensive copper in brake materials, which not only improves the performance of braking materials but also reduces their costs.

Abstract ：
In this paper, the responses of machined surface roughness and milling tool cutting forces under the different milling processing parameters (cutting speed v, feed rate f, and axial cutting depth a(p)) are experimentally investigated to meet the increasing requirements for the mechanical machining of T2 pure copper. The effects of different milling processing parameters on cutting force and tool displacement acceleration are studied based on orthogonal and single-factor milling experiments. The three-dimensional morphologies of the workpieces are observed, and a white-light topography instrument measures the surface roughness. The results show that the degree of influence on S-a (surface arithmetic mean deviation) and S-q (surface root mean square deviation) from high to low level is the v, the f, and the a(p). When v = 600 m/min, a(p) = 0.5 mm, f = 0.1 mm/r, S-a and S-q are 1.80 mu m and 2.25 mu m, respectively. The cutting forces in the three directions negatively correlate with increased cutting speed; when v = 600 m/min, F-x reaches its lowest value. In contrast, an increase in the feed rate and the axial cutting depth significantly increases F-x. The tool displacement acceleration amplitudes demonstrate a positive relationship. Variation of the tool displacement acceleration states leads to the different microstructure of the machined surfaces. Therefore, selecting the appropriate milling processing parameters has a positive effect on reducing the tool displacement acceleration, improving the machined surface quality of T2 pure copper, and extending the tool's life. The optimal milling processing parameters in this paper are the v = 600 m/min, a(p) = 0.5 mm, and f = 0.1 mm/r.
