Reclamation Information Sharing Environment (RISE)

The open circuit potential of cold-rolled and additively manufactured (AM) 316L stainless steel was measured. The AM parts underwent a variety of post-processing procedures including grinding and polishing, heat treatment, and a novel sensitization and etching process (used to remove support material). Microstructures and surface roughness of each specimen were evaluated, and specimens also underwent testing in an x-ray diffractometer. The as-printed specimens had the best corrosion resistance and the heat-treated specimens had the worst.
