Summary
Metal additive manufacturing (MAM), central to Industry 4.0, has drawn significant interest in sectors such as medical, aerospace, energy, and automotive. However, widespread adoption remains limited due to concerns over inconsistent material properties and a lack of full understanding of how novel microstructures impact performance. To address these challenges, the OpenCorrAM project will investigate the corrosion behaviour of additively manufactured materials, such as austenitic stainless steels, nickel-based superalloys, and titanium alloys. Using high-resolution microscopy, microcapillary electrochemical techniques, and surface analysis, the project will study passive layer formation and breakdown. By comparing AM materials with conventionally manufactured ones, it will provide new insights into corrosion science. Project findings will benefit industry, research, and policymakers by improving material performance, sustainability, and safety.
The project team will develop a comprehensive, open-access database that interrelates processing, (micro)structure, and performance of AM alloys, with focus on corrosion aspects. This database will advance the state of knowledge, foster innovation in materials science and engineering, and help overcome barriers to the broader implementation of MAM technologies.

Open Science project, Industry cooperation, Main RI concerned, Cross-domain/Cross-RI
The growing adoption of MAM faces significant hurdles, particularly the high variability in material properties and the unclear connections between novel microstructures and their performance. This inconsistency limits the full-scale implementation of MAM across industries requiring reliable corrosion resistance, such as aerospace and energy. The need for a systematic approach to understanding the corrosion behaviour of additively manufactured materials is crucial for fostering confidence in their use.
Solution
Employing advanced high-resolution and microcapillary electrochemical techniques, OpenCorrAM strives to create an open and comprehensive database of intercorrelated results in the different fields of MAM performance analysis, that catalogues the corrosion characteristics of various additively manufactured materials. These investigations serve to provide exceptional insights into micro and submicron structural details, as well as the electrochemical and corrosion properties. Machine learning techniques will analyse the data, establishing relationships between microstructural features and corrosion behaviours, thereby enhancing predictive capabilities in materials performance.
Scientific Impact
OpenCorrAM not only enhances the scientific understanding of corrosion in additively manufactured materials but also revolutionises the field through the establishment of an open-access knowledge base.
By enabling access to a broad collection of data and findings, and by integrating machine learning techniques to analyse data and identify relationships between microstructural features and corrosion properties, OpenCorrAM helps standardise methods and approaches in corrosion studies related to AM materials, responding to the widely recognized strong need to open corrosion data to develop and feed predictive models in corrosion science. The project thus fosters collaboration and innovation, driving advancements in corrosion studies and supporting the MAM industry’s growth.
