Laser-induced breakdown spectroscopy (LIBS) of LPBF-fabricated alloy steel: effect of surface roughness and the laser–material interaction mechanism
This study examines how surface roughness influences LIBS spectral quality in LPBF alloy steel. Roughness balances reflectivity, ablation threshold, and plasma effects to govern signal stability, with optimal quality at medium roughness levels.
