Corrosion Investigations of Additively Manufactured Alloys
Abstract
Additive manufacturing has been highlighted in the DOD as a means to reduce operational costs (production and storage costs) on parts that are highly complex and expensive. For example, the ability to leverage AM to generate parts on demand with no need for post-processing eliminates the substantial costs associated with the storage and care of parts in quantity. The advantage of AM is greatly compromised if the parts corrosion behavior results in catastrophic failure in the field. Recent research indicates that the origin of corrosion in AM parts is closely related to the processing conditions of AM materials. The key to unlocking improved corrosion resistant parts directly out of the AM systems relies on precise control of machine parameters and input materials. The focus of this work is to investigate both machine parameters and feedstock optimization to develop robust 316L materials directly out of the AM system while eliminating the need for additional processing.
