Surface specifications are important to materials in any application, and the manufacturing method does not exempt any materials from this requirement. Additively manufactured materials pose new challenges for the preparation of materials to meet surface specifications. While metal additively manufactured materials may or may not have specific requirements for corrosion resistance, corrosion testing can be a sensitive indicator for the demonstration of equivalent performance. We have been developing surface preparation methods, including traditional and novel electropolishing methods for specific additively manufactured metals. To demonstrate equivalence, we have subjected these materials to corrosion testing and compared the results to equivalent materials prepared by traditional manufacturing methods. Some of the surface preparation techniques and associated corrosion testing will be presented for 316L stainless steels.
