Bioinspired femtosecond laser surface texturing for enhancing tribological properties of Ti6Al4V titanium alloy

This study investigates bioinspired femtosecond laser surface texturing (FsLST) for tribological enhancement of Ti6Al4V alloys. Femtosecond laser ablation (@800   nm) was used to fabricate four configurations of bionic micro-textures, of which surface properties were systematically characterized. Dry sliding tests against zirconia (ZrO 2) balls revealed that optimized micro-grooves with 30 μm spacing reduced the coefficient of friction (COF) by 55.13% and wear rate by 62.59% compared to the polished surface. The improved performance and mitigated abrasive wear were attributed to the synergistic effect of contact interface reduction, enhanced debris entrapment capacity, and further formation of protective titanium dioxide/suboxide layers. Such findings confirm FsLST as an efficient approach for designing bioinspired anti-wear surfaces with potential prospects in enhancing durability and friction control.
