Artícle publicat en la revista Materials MDPI en col·laboració amb investigadors de la Universitat de Cantabria i de Technische Universität Wien: Additive Manufacturing Processes in Selected Corrosion Resistant Materials: A State of Knowledge Review.
Highlights
- A full review article on the corrosion behaviour of additive manufacturing (AM) of metallic parts is presented with the aim of covering the significant lack of information on this subject.
- Corrosion resistance of light metallic systems and duplex stainless steels objects obtained by additive manufacturing (AM) processes is critically discussed, based on the synergism between variables linked with chemical composition, manufacturing processes, and service conditions.
- Methodologies for improving the corrosion resistance of metallic parts produced by additive manufacturing (AM) are highlighted.
- The available data allow us to state that potentiodynamic corrosion tests are the best methodology to characterize metal additive manufacturing (MAM) corrosion and this unique test should be selected for the evaluation of this phenomenon. There is a gap in knowledge and test procedure to properly identify the relationship between defects and corrosion behaviour of the most studied metal additive manufacturing (MAM) systems.
