The Corrosion Behavior of 316L Stainless Steel Additively Manufactured by Direct Energy Deposition Process

Materials Proceedings, 2021
Traditional additive manufacturing (AM) technologies tend to focus on powder bed fusion (PBF) methods, such as SLM (selective laser melting) and EBM (electron beam melting), that are attractive for the rapid production of complex components.
