文摘

Process windows for spot hardening and melting determined Diameter and depth of the laser treated region numerically and experimentally evaluated Key parameters for the simulation evaluated fitting experimental data. The proposed tuning procedure based on multi-objective optimization revealed effective. The fabrication of bio-mimetic surfaces is possible implementing the process maps.
