A new method that combines the fractal theory, Weibull distribution and genetic algorithm (GA) is proposed in the present study to generate engineering non-Gaussian rough surfaces (NGS) with specified kurtosis and skewness. By adjusting the GA parameters, the generated surfaces cover the NGS corresponding to various machining methods used in engineering. Good agreement was found when compared with real engineering rough surfaces measured experimentally. Compared with the methods in the literature, the advantages of the present method include generating rough surfaces with a much wider range of specified kurtosis and skewness, and with scale-independent and more realistic topography.

This study investigates the effects of annealing temperatures on the microstructure, mechanical properties, and tribological performance of Mn8/SS400 bimetal composite (BC) produced via hot-rolled bonding. Results show that annealing led to a microstructural transition in the Mn8 layer from a fully austenitic structure to a multiphase structure containing pearlite, ferrite, bainite, and retained austenite. The SS400 layer transformed from the bainitic ferrite (BF) and martensite/retained austenite (M/RA) to a more stable bainitic structure. Annealing at 600 °C resulted in optimal mechanical properties, with ultimate tensile strength (UTS) reaching 755.7 MPa and the best wear resistance. This enhancement is attributed to the synergistic strengthening provided by the multiphase microstructure and interfacial element diffusion across the interface. Higher annealing temperatures (700–800 °C) promoted the formation of intermetallic compounds (IMCs), reducing the interfacial diffusion layer width and consequently influencing wear behaviour. The study highlights that the multiphase strengthening and interfacial bonding between the Mn8 and SS400 layers are key to achieving superior mechanical and tribological performance, with the 600 °C annealed sample exhibiting the best overall properties.

Laser additive technology is commonly utilized to prepare strengthened coatings on Ti6Al4V without considering surface precision and deformation. A secondary surface finishing is cumbersome with low productivity. Therefore, integrated laser alloying-grinding is proposed by combining laser additive strengthening with grinding subtractive shaping. The B4C coatings are prepared for boron-carbon alloying of the Ti6Al4V. The high-energy laser makes the grinding process stable. The roughness Sa of the integrated laser alloying-grinding surface is reduced by 51 % compared to the conventional machined surfaces. The alloyed surface hardness reaches 750 HV, and its wear and corrosion resistance far exceeds that of the Ti6Al4V matrix. The integrated laser alloying-grinding can realize Ti6Al4V surface property-accuracy synergistic manufacturing and present in-depth theoretical instruction for surface anti-fatigue fields.

Natural articular cartilage, devoid of lymph and blood vessels, has limited self-repair capacity but can function for up to 70 years. Its remarkable longevity is attributed to its porous, water-containing structure and lubrication from brushlike polymers. In this study, simulating structure and lubrication mechanism of natural articular cartilage, a composite structure incorporating pores and brushlike polymers was constructed on bearing interface of UHMWPE artificial joint. The biomimetic bearing interface achieved a boundary-fluid mixed lubrication mechanism, demonstrating ultra-high wettability (0° contact angle) and low friction coefficient (0.03) comparable to that of natural articular cartilage, while also exhibiting a relatively long lifespan. This study presents a promising technology for fabricating super-lubricated bearing interfaces mimicking natural cartilage and elaborates a unique lubrication mechanism.

Spine-based grippers and robots have found extensive applications in fields such as climbing, exploration, and rescue. This study develops a frictional engagement theory based on 3D surface morphology, addressing the engagement capability and probability on rough surfaces. Results indicate a positive correlation between engagement capability—quantified by the detachment force to preload ratio ()—and the proportion of the concave engagement area, which can be predicted through surface morphology analysis. The investigation into engagement probability reveals that pre-engagement displacement, characterized by the parameter from the modified probability equation, varies with surface roughness, initially decreasing and then increasing. Theoretical predictions are validated through Monte Carlo simulations and experiments, enhancing the understanding of frictional engagement mechanisms and providing design guidance for spine-based systems.

This study aimed to develop a high-friction tread design by utilizing fluid flow. Inclined-groove tread rubber specimens designed to generate negative fluid pressure were prepared and friction tests under glycerol lubrication were conducted. The results showed that the inclined-groove specimens generated negative fluid pressure and achieved a higher friction coefficient than did the rectangular-groove specimen. The results also indicated that a tread block with an inclined-groove shape with a small groove depth is desirable for achieving high adsorption force and friction, and for a given adsorption force, a tread block with a large convex plateau region is desirable. Our research showed that when the groove shape was controlled, the fluid flow could be adjusted to increase the tread rubber friction.

Glycerol is an abundant, inexpensive, biodegradable substance that is environmentally safe and has low potential for bioaccumulation. We evaluated its tribological performance, neat and emulsified with 4 %wt of oleic acid, using friction maps encompassing surface kinematics typical of mechanical devices such as roller bearings, camshafts, and gears. We set the maximum Hertz contact pressure around 1.0 GPa to achieve the elastohydrodynamic lubrication regime in a ball-on-disk apparatus. The entrainment speed ranged from 0.1 to 2.0 m/s, and the slide-to-roll ratio between 10 % and 30 %. The measurements were made at 40 °C and 100 °C. Under these conditions, extensive portions of the friction maps showed ultralow friction (≤ 0.01). The regression models developed are consistent with lubrication mechanisms accepted for similar tribosystems and exhibit a coefficient of determination R2 better than 90 %.

The phenomenon of friction increase in graphenic materials during prolonged treatment in an oxygen plasma environment has been widely recognized. In this study, we report a possible oxidation state that leads to decreased friction during oxygen plasma treatment of graphenic materials through molecular simulations. We also propose a simple, clean, and efficient method to control the reverse structural evolution for controlled oxidation. Experimental applications demonstrated a 30.6 % reduction in friction and a 130.1 % increase in friction for short and long oxygen plasma treatments, respectively, compared to the initial graphenic vacancy structure. These findings contribute to an increased understanding of the response and modulation of graphenic coatings in oxygen plasma environments.

In this study, we investigated the friction mechanisms behind the observed changes in friction of niobium diselenide (NbSe2) thin films under varying normal bias voltages. The results show that both the friction force and coefficient of friction (COF) increase with the application of positive and negative bias voltages. These friction changes are significantly affected by the electrostatic force on the sample surface and the electronic excitation during friction leads to energy dissipation, ultimately increasing friction. These findings not only increase our understanding of the interfacial friction phenomenon of nano-electric friction, but also help to control energy dissipation of sliding nanofriction, making electronic control of friction possible.

The research focuses on the issue of excessive skidding for cylindrical roller bearings. The oversimplified thermal analysis module of the rolling bearing dynamics analysis software ADORE was improved with the thermal resistance network method and lubricant distribution. Based on the improved ADORE, the variation mechanism of skidding and the critical radial load for skidding of cylindrical roller bearings were analyzed. The findings indicate that the slip rate and the sliding velocity decreases exponentially with increasing radial load, and 5 % is chosen as the evaluation criterion for the degree of skidding. A method for calculating the critical radial load for skidding of NU-type bearings is proposed, which has reference value for the design of cylindrical roller bearings with low slip rates.
