Elemental analysis improves with better surface roughness in alloy steel components.
A key finding indicates a strong relationship between surface roughness and LIBS outcomes.
Analysis of laser-induced breakdown spectroscopy on LPBF-fabricated alloy steel was conducted to optimize results.
This highlights the need for surface condition control in LPBF manufacturing processes.

Implication

Laser-Induced Breakdown Spectroscopy reveals surface roughness impact on elemental analysis in LPBF components, suggesting optimization.

Abstract

Laser-induced breakdown spectroscopy (LIBS) is an ideal method for the online elemental analysis of laser powder bed fusion (LPBF) components due to its in-situ and rapid characteristics. However, the inherent...
