Corrosion Behaviors of Additively Manufactured Stainless Steel Coated with Epoxy

In this study, the corrosion behavior of additively manufactured (AM’d) or 3D printed 316L stainless steel (SS) coated with an epoxy coating was studied. Four types of samples were used, 3D printed stainless steel with coating, 3D printed without coating, conventional with coating, and conventional without coating. The corrosion behaviors of the samples were measured. It shows that the epoxy coating layer significantly improved the samples' corrosion resistance.
