The research work presented targets the hatch distance and scanning angle of laser sintering parameters with respect to characteristics on the 6061-T6 curved aluminum alloy surface. The research work aims to solve processing problems that are associated with curved geometries, as their thermal and mechanical behavior during laser remelting is somewhat different from flat surfaces. Surface morphological features and roughness were altered with the help of a fiber laser. Scanning speed, power, and frequency were systematically changed. The obtained results have pointed out that hatch distance and scanning angle significantly affect surface uniformity and roughness. For instance, a smaller hatch distance with a higher scanning angle leads to i) better uniformity of the texture; ii) at an inferior scanning speed, the grooves will be deeper, leading to higher roughness. These studies help in optimizing laser parameters for obtaining better surfaces, which is very important in aeronautic applications where precision and material performance are the main issues. This research not only deepens the understanding of laser treatment on a curved surface but also points to practical implications for the enhancement of adhesion and friction reduction for various industrial components. Key words: laser sintering, surface roughness, 6061-T6 aluminum alloy, hatch distance, scanning angle.
