The wide adoption of Laser Powder Bed Fusion (LPBF) in additive manufacturing has led to the need for a comprehensive understanding of the corrosion behavior of LPBF-fabricated components [1]. This thesis focuses on the pitting corrosion behavior of 316L stainless steel, emphasizing the influence of process-induced porosity. The impact of various defects on pitting corrosion behavior was explored through a series of experimental investigations using cyclic potentiodynamic polarization in a 0.6M NaCl solution. The study revealed that LPBF 316L SS exhibited superior pitting resistance compared to its wrought counterpart [2]–[7], even in the presence of manufacturing defects. Interestingly, despite their larger size and open porosity, gas voids were not the preferred sites for pitting propagation. The presence of these voids did not accelerate the accumulation of metal cations, thus dimin...
