Abstract
1030-nm 320-fs-laser pulses were used to irradiate surface of Ti6Al4V titanium alloy in air and water environments. Laser-induced periodic surface structures (LIPSS) were produced at variable laser fluence F0 = 0.08–1.2 J/cm2 and accompanying changes in topography and elemental/phase composition were studied by SEM, TEM, AFM, and XRD. After high-fluence laser texturing in air, resulting in rough micro-protrusions covered by LIPSS and TiO layer, the microhardness was improved by 25 % and residual tensile stresses detected at a depth of 2.3 μm beneath the structure, reached 150 MPa. Compressive stresses induced by laser texturing at F0 ≤ 0.4 J/cm2 in air were shown to have a minimal effect on fatigue life.
