| Abstract Scope |
Laser beam powder bed fusion (LB-PBF) is a modern manufacturing technique for complicated metal components. It can produce parts with complex organic designs but often results in tortuous as-printed surfaces and heterogeneous microstructures which result in unexpected corrosion susceptibility. This study will investigate the susceptibility of LB-PBF stainless steel samples to atmospheric environments, like those in marine applications. While stainless steels exhibit good general corrosion resistance, in chloride containing environments, they are susceptible to localized corrosion and pitting. The localized corrosion susceptibility of LB-PBF 316L stainless steel exposed to an artificial seawater atmospheric corrosion environment (40% relative humidity at 35oC) with a fixed contaminant level will be assessed. Different surface preparation techniques will be explored, including: as-printed, electropolished, and chemically cleaned conditions. Post-exposure corrosion damage will be quantified with electron microscopy and optical profilometry.
