Abstract

© 2022 Elsevier LtdFeedstock modified powders were produced by ball-milling commercial 316 L stainless steel powder and 1 wt% additive (Cerium oxide–CeO2, lanthanum (III) nitrate hexahydrate–La(NO3)30.6 H2O and chromium nitride–CrN). Laser-powder bed fusion (L-PBF) was performed on modified feedstock using 180, 200, and 220 W laser power. The influence of additives on microstructure and corrosion performance was investigated on the as-printed and ground/polished conditions of L-PBF-316 L-additive. The corrosion performance was dependent on the type of the additives. The microstructure of the alloys was correlated with the observed corrosion behavior.
