Abstract: Laser surface texturing (LST) technology improves the surface morphology and characteristics of materials by modifying their texture and roughness. The different behaviors during wettability test, depending on the texture pattern and number of passes suggest a complex dependence on the surface microstructure and the dynamics of surface energy change. Laser texturing significantly alters the coefficient of friction (COF) and wear behavior of the materials analyzed in this study PA6.6 and PA6.6 reinforced with glass microspheres. The increase in surface roughness after texturization is the main factor driving the higher COF values. Textured patterns have a functional role in the accumulation of wear debris, which contributes to the improvement of the wear behavior of textured surfaces. All tests showed a weight increase after degradation, suggesting incomplete degradation or chemical reactions with the test environment. The studied materials can be used in industrial applications such as functional coatings, components in the filtration industry, wear parts in the mechanical industry.
