| Abstract: | The corrosion response of heat-treated C63020-NAB alloys fabricated through laser-powder bed fusion (L-PBF) and laser-directed energy deposition (L-DED) techniques was assessed in NaCl solution on surfaces parallel and perpendicular to their building direction. Microstructural analyses revealed a stronger texture formed in the L-PBF NAB, while the L-DED NAB exhibited a slightly more isotropic behavior characterized by a finer microstructure and more equiaxed grains on both surfaces. Corrosion performance analysis indicated isotropic corrosion behavior in both L-DED and L-PBF NAB, though the L-DED NAB showed marginally better corrosion resistance. The microstructural characteristics were identified as the primary factor driving the passivity and corrosion resistance of the alloy. [Display omitted] • Corrosion behavior of L-PBF and L-DED NAB evaluated in NaCl solution. • L-DED NAB showed a uniform microstructure with fewer precipitates than L-PBF NAB. • Corrosion resistance improves over time in both L-PBF and L-DED NAB. • Both L-PBF and L-DED NAB exhibit isotropic corrosion and passive behavior. • L-DED NAB demonstrates marginally superior corrosion resistance to L-PBF NAB.
