Résumé
Surface engineering by laser remelting is a niche advanced manufacturing technology that purposely modifies a surface topography without the addition or removal of material Laser remelting occurs through redistribution of molten material along a designated laser path trajectory. This study focuses on the analysis of temperature evolution along a scanning trajectory during surface patterning by laser remelting. For this purpose, several laser remelting experiments were performed while recording live and with high speed the temperature as well as the scanning trajectory in the laser-material interaction zone. Two sample trajectories - square and octagon - were followed with a constant power of 30 W and scanning speeds of 100 mm/s and 300 mm/s. After this, surface topographies were measured to relate surface profile variations to temperature evolution. The preliminary results obtained indicated that the evolution of the temperature distribution predominantly depends on process parameters such as scanning speed, trajectory length, pattern configuration, and laser power. These findings open up new directions in the development of scientific knowledge and engineering solutions geared towards AI-based control and optimization of the laser remelting processes.
