Electrochemical behavior of alloy 22 processed by laser powder bed fusion (L-PBF) in simulated seawater and acidic aqueous environments

Corrosion resistance of additively manufactured (AM) alloy 22 using Laser Powder Bed Fusion (L-PBF) was studied and compared with their wrought counterparts in 5 wt.% NaCl (pH ∼ 7.0) and 5 wt.% NaCl + 1.0 M HCl (pH ∼ -0.5) solutions. The l-PBF process parameters were selected from two extremes of a...
