AMPP TR21522 was formed in July 2021 with the goal of assessing the state of the art with respect to corrosion testing of additive manufactured materials. A group of about 35 subject matter experts were assembled to prepare a summary report. An assessment of the open literature resulted in the selection of about 340 relevant references that were evaluated with respect to corrosion mechanism, material and additive manufacturing process.

The corrosion mechanisms investigated included general and localized corrosion, environmental cracking (such as SCC, SSC and HISC) and high temperature oxidation. The scope was limited to metallic materials of construction. The results of this assessment are presented with identified knowledge gaps and recommendations for corrosion testing that have been identified as of November 2022.
