Optimizing Laser Ablation of Stainless Steels for Volume Removal and Surface Quality Using Burst of Pulses

open access: yesAdvanced Engineering Materials, EarlyView.
This study explores the ablation efficiency and surface quality of laser‐treated stainless steel alloys (AISI 304, AISI 420, and AISI 316Ti) using an ultrashort pulsed laser and varying burst parameters (MHz, GHz, and Bi‐burst). Both ablation rates and surface quality parameters are determined, including isotropy surface roughness values, highlighting ...

On the Investigation of a Sustainable Two Step Laser‐Based Surface Treatment for the Functionalization of Additive Manufactured Ti–6Al–4V Components

open access: yesAdvanced Engineering Materials, EarlyView.
This study developed a two‐step laser‐based process for sustainable surface treatment of Ti–6Al–4 V components, combining laser polishing and direct laser interference patterning with ns and ps pulses. Key findings include significant roughness reduction, hierarchical patterning with ps pulses, and improved homogeneity. A cost function is developed for
