Martensitic stainless steel (MSS) has high hardness, mechanical strength, tribological performance, and corrosion resistance at milder temperatures. Additive manufacturing (AM) has brought industrial possibilities, such as customized geometries, on-demand production, and lead-time decrease. AM by laser directed energy deposition (L-DED) is intended for the building and repair of large parts. However, challenges arise due to the martensite brittleness and L-DED complex thermal history. Alternatively, lower C-content MSS can be used, as they offer a comparable property set with easier processability. In the L-DED, careful parameterization is required. There is still a dearth of literature regarding the L-DED processing of MSS for corrosion control. Within this context, the current study attempts to assess the corrosion resistance of a low C MSS (0.01 wt.%) multilayer samples built by AM L-DED AISI 410L in two parameterizations. Production (PRO), with a higher deposition rate, is meant for the building of bulker parts. Resolution (RES), with a lower deposition rate, is meant for more complex geometries. Two L-DED experiments were performed, one for PRO and the other for RES. Standardized multilayer samples were built in an argon-controlled atmosphere to mitigate the insertion of oxygen and impurities. Archimedes’ density, microstructure, hardness, and electrochemical corrosion by potentiodynamic polarization in a 3.5% NaCl solution at room temperature analyses were performed. Samples of a commercial hot-rolled and annealed 410 MSS with a higher C-content (0.15 wt.%) were used as reference material (410-REF). Results showed compatible density levels (99.95%) in both L-DED optimized parametrizations. The L-DED microstructure obtained was biphasic with ferrite and refined martensite laths concentrated at the grain boundaries, owing to the laser fast cooling and AISI 410L lower C-content. The RES parameter produced a more refined microstructure, with a larger grain boundary area and 7% higher hardness than the PRO one, due to the faster solidification of the first condition. The 410-REF, in turn, showed a coarse ferrite plus tempered martensite and Cr-carbides, with a significantly lower hardness regarding both L-DED conditions. Electrochemical test data revealed a more positive corrosion potential Ecorr and a lower corrosion current Icorr for the RES parameter, which suggests a more effective passivation of this regarding the L-DED PRO and 410-REF. This indicates that lower C-content AISI 410L processed by L-DED at lower energy densities will be more resistant to corrosion in the presence of chlorides.
