“…In the development of laser technology, laser texturing on surfaces has been used to investigate how to reduce the coefficient of friction (COF) on surfaces ( Zhan et al, 2019 ; Wan et al, 2021 ). However, rough surfaces have the natural advantage of increasing the interaction force between the friction surfaces, which serves to increase friction ( Babic et al, 2019 ; Jain and Bajpai, 2022 ). Developments in the field of bionics promote advances in laser surface texturing (LST) technology ( VENCL et al, 2019 ; Amziane et al, 2023 ).…”

Introduction: In recent research, the expansion in the use of Mg alloys for biomedical applications has been approached by modifying their surfaces in conjunction with micro-arc oxidation (MAO) techniques which enhance their abrasion and corrosion resistance.Methods: In this study, combining laser texturing and MAO techniques to produce the dense ceramic coatings with microstructures. On the surface of the AZ31 Mg alloy, a micro-raised annulus array texture has been designed in order to increase the surface friction under liquid lubrication and to improve the operator’s grip when holding the tool. For this work, the micro-morphology of the coatings was characterised, and the friction properties of the commonly used scalpel shank material 316 L, the untextured surface and the textured surface were comparatively analysed against disposable surgical gloves.Results and discussion: The results show that the Laser-MAO ceramic coating grows homogenous, the porosity decreases from 14.3% to 7.8%, and the morphology after friction indicates that the coating has good wear resistance. More specifically, the average coefficient of friction (COF) of the three types of gloves coated with Laser-MAO ceramic was higher than that of the 316 L and MAO ceramic coatings under the action of the annulus-integrated texture under the lubrication conditions of physiological saline and defatted sheep blood, which achieved the goal of increasing friction for the purpose of helping to prevent the problem of tool slippage from the hand.

“…Ti6Al4V, a titanium alloy, possesses exceptional mechanical properties, a high strength-to-weight ratio, and excellent corrosion resistance, making it widely used in various industries, including aircraft [6], automotive [7], and medical [8]. However, the native surface of Ti6Al4V material exhibits high wettability, leading to a tendency to attract and retain water droplets.…”

This study aims to investigate the impact of laser parameters, including laser power, laser frequency, laser scan speed, and hatches line distance, on Ti6Al4V to create superhydrophobic surfaces. Surface profile and roughness play vital roles in achieving superhydrophobicity, and existing laser surface modification methods are time-consuming and lack subsequent steps for optimizing desired characteristics. A factorial design was implemented, varying laser power (12 and 18 W), laser frequency (40 and 60 kHz), laser scan speed (180 and 220 mm/s), and hatch line distance (0.25 and 0.45 mm). Surface morphology and topological properties were analyzed for surface characterization. The results demonstrate a significant increase in surface roughness profiles such as Sa and Sq by 6 and 5 times, respectively, compared to the untextured surface. These modifications also led to enhancements in surface topological properties. Regression analysis revealed the importance of controlling the surface profile for achieving superhydrophobicity. Statistical analysis indicated that laser power, laser frequency, and laser speed were the most significant parameters contributing to superhydrophobicity. The optimum laser parameters for superhydrophobic surfaces were determined as 18 W laser power, 40 kHz laser frequency, and 220 mm/s laser scan speed. In conclusion, this study emphasizes the critical role of surface topological properties in creating superhydrophobic surfaces on Ti6Al4V. Laser texturing techniques successfully improved surface roughness and profile, facilitating the development of superhydrophobic surfaces. These findings offer valuable insights for advancing surface engineering, with potential applications in the aerospace, automotive, and biomedical industries.

“…However, there are some limitations to using titanium alloy in harsh and extreme abrasion conditions because of its properties like poor shear strength, poor wear behavior, low hardness, etc. [6][7][8]. Titanium also has high material and cost of production [9].…”

The present work emphasizes the fabrication of a series of V-groove channels utilizing electrical discharge machining using a pointed tungsten tool electrode. The prepared textured surface is tested for the shape of V-groove channel, wetting behavior, and tribological aspect. A decrease in shape error of V-groove channel is observed as the peak current increases from 4 A to 10 A due to an increase in discharge energy which functions as the melting or vaporizing of machined materials. The water contact angle decreases from 61.316 0 (untextured surface) to 49.567 0 (sample 4) showing an increase in hydrophilic behavior for the samples having nearly a V-groove-shaped channel. Further, there is a decrease in COF value from 0.48 (untextured surface) to 0.23 (sample 4). The decreased COF value attributes to the formation of metallic bridges in the V-groove channel. The prime wear mechanism for an untextured surface is found to be ploughing whereas adhesion with ploughing is dominant for textured surfaces.
