AB Most of the current works based on surface treatments of metals by laser marking technologyare focused on the modification of the color tonality of flat surfaces, or the development of specifictopography features, but the combination of both processes is not usually evaluated, mainly dueto the complexity of controlling the optical properties on rough surfaces. This research presents ananalysis of the influence of the micro-geometrical characteristics of periodic patterned laser tracks onthe chromaticity and reflectance of Ti6Al4V substrates. The samples were irradiated with an infrarednanosecond pulsed laser in air atmosphere, taking as the control parameter the scan speed of the beam.A roughness evaluation, microscopic inspection, and absorption and chromaticity examination wereconducted. Although micro-crack growth was detected in an isolated case (10 mm/s), the possibilityof adjusting the result color was demonstrated by controlling the heat-a ected zone thickness of thetextures. The results of rough/colored combined textures allow new perspectives in industrial designto open, particularly in aesthetic applications with special properties.
