Summary: ZK60 magnesium alloy was treated with laser shock peening at different laser energy densities and then fretting corrosion wear tests were conducted on the treated and untreated samples. The relationships between microstructure, residual stress, surface hardness, tensile strength, corrosion resistance, and fretting corrosion wear behavior were analyzed. Results showed that laser shock peening treatment can reduce fretting corrosion wear volume by up to 73.4%. The improvement in surface hardness, tensile strength, and corrosion resistance due to fine grain strengthening, dislocation and twinning-induced strain hardening, and compressive residual stress contribute to the reduction of fretting corrosion wear.

Summary: The study investigated the effects of laser shock peening and low-temperature vacuum carbonitriding on the tribological properties of 20Cr2Mn2Mo steel alloy. It was found that the surface roughness and microhardness increased with higher laser energy and number of impacts, leading to an increase in coefficient of friction. Laser shock peening and carbonitriding resulted in high-density dislocations and second-phase particles, changing the primary wear mechanism from abrasive wear to a mix of abrasive and adhesive wear with increasing energy and impacts.

Summary: The effect of laser peening without coating (LPwC) on the tribological behavior of Ti-6Al-4 V alloy at ambient and elevated temperatures was investigated. The results showed that after peening, the samples had maximum compressive residual stress and increased hardness. Additionally, the LPwC samples exhibited a decrease in average grain size and an increase in low-angle grain boundaries compared to the unpeened samples. The wear mechanisms of the LPwC samples were milder than those of the unpeened samples, resulting in reduced wear volume loss.

Summary: The study found that under different sliding conditions, dimples defined by nanosecond laser exhibited the lowest steady-state coefficient of friction, while in Hank's solution, lines and crosshatching showed better frictional characteristics after running-in and the removal of bulges around the laser textures. In terms of wear resistance, low-density lines pattern and particularly dimples were the most promising in contact situations likely to occur during starved/dry-lubrication conditions.

Summary: ZK60 magnesium alloy is refined through submerged friction stir processing (SFSP), leading to the observation of high-strain-rate superplasticity (HSRS) at elevated temperature. The excellent HSRS is attributed to the uniform fine-grained structure and the relatively high fraction of high-angle grain boundaries, which facilitate grain boundary sliding. Additionally, the presence of dispersed fine particles/precipitates enhances the microstructural stability of the specimens.

Summary: The addition of Ce element can significantly improve the microstructure of ZK60 alloy, reducing grain size and increasing the total fraction of precipitates, thereby enhancing the mechanical properties of the alloy. Ce element can also improve the wear resistance of the alloy, enhancing wear resistance under low load conditions and providing a protective oxide layer under high load conditions. However, under severe oxidation conditions, the microstructural evolutions caused by Ce addition do not contribute to the enhancement of wear resistance.

Summary: The macro-sliding and micro-scratching behaviors of a Mg65Zn30Ca5 bulk glassy alloy (BGA) were investigated. The wear mechanism of the Mg-based BGA during dry sliding includes abrasion and oxidation wear. Increasing the normal load does not alter the wear mechanism of macro-sliding. The subsurface morphology beneath the worn scar exhibits brittle cracks across shear bands.

Summary: Compared with traditional laser shock peening, femtosecond laser shock peening (FLSP) offers greater flexibility and efficiency as it can be performed directly in air without ablative or confinement layers. In this study, FLSP was successfully applied to AZ31 magnesium alloy sheet, and the influence of pulse energy on surface morphology, microstructure, residual stress, and hardness was investigated. The results showed that varying the pulse energy effectively improved the surface integrity of the material, increasing surface roughness, microhardness, residual compressive stress, and creating twin boundaries and grain refinement layers near the surface. However, excessive pulse energy may inhibit the enhancement of surface integrity due to thermal effects and surface oxidation.

Summary: In this study, a elasto-plastic constitutive model of friction incorporating the concept of superloading surface was developed based on the subloading friction model. The proposed model achieves a smooth transition of friction by describing the evolution rule of structure, treating the state with static friction coefficient larger than kinetic friction coefficient as the bulkiness of structure. The positive definiteness of the plastic multiplier, loading condition, and material parameters were derived, and the validity of the proposed model in accordance with the subloading-friction model was confirmed through a stick-slip simulation of a mass-spring system.

Summary: This paper investigates the influence of preparation strategies on the lubrication properties of surface textures. Three laser scanning strategies are proposed to achieve a sinusoidal textured surface, and the evolution of surface structure and chemical composition is discussed. The findings show that ridge structures enhance anti-wear properties but also increase the friction coefficient. However, the oil cover preparation method prevents the formation of ridges and improves wettability.

Summary: This study presents a systematic approach to generating control signals for a tactile simulator that simulate the touch of textile fabrics. By using a friction modulation tactile surface and acquiring forces from real surfaces with artificial finger mimicking fingerprints, control signals are generated and processed in the frequency domain before sending them to the tactile stimulator. The study focuses on the potential benefits of incorporating fingerprint information in fabric simulations to achieve a more realistic tactile perception. A sensory analysis with 36 participants using the generated control signals showed better discrimination without fingerprint information.
