Abstract

This work explores the relation between microstructural features and pitting corrosion resistance of additively manufactured 316 L stainless steel. Specimens fabricated using two different laser-based manufacturing processes (L-PBF and L-DED) were studied in as-built and heat-treated conditions following a comparative approach. Potentiodynamic polarization tests and corrosion morphology analysis served to evaluate their corrosion resistance and passive behavior. This work shows that, contrary to previous reports, the absence of MnS inclusions or presence of the microsegregation structure are not the main factors enhancing passivity of these materials. Instead, dislocation density was the only microstructural feature matching the trend in their passivity behavior.
