Understanding the Role of Laser Shock Processing and Micro-Texturing on the Tribological Performance of Ti-6Al-4V
Original language description
The wear resistance of Ti-6Al-4 V, crucial for industrial and biomedical components, was investigated through a hybrid approach combining Laser Shock Peening (LSP) and laser micromachining. The aim was to evaluate the influence of residual stress and surface geometry on tribological behavior. Hierarchical micro-nano structures with pillar diameters of 10-40 mu m and heights around 8 mu m were fabricated on both LSP-treated and pristine surfaces. The coefficient of friction (CoF) remained stable up to 600 cycles for all textures, with average values of 0.13-0.16 under lubricated conditions. Surfaces with 10 mu m micropillars showed a 35% reduction in wear volume compared to flat references, while wider pillar geometries led to faster film breakdown and higher wear. The LSP treatment did not produce significant differences in friction or wear, confirming that texture geometry, rather than residual stress, governs tribological response. These findings clarify the role of hybrid laser processing and provide guidelines for optimizing surface design in Ti-6Al-4 V components.
