Education and Training Series #90: Directed Energy Deposition Process of Corrosion Resistant Coating for Lead-Bismuth Eutectic Environment

These webinars, organised by the GIF Education and Training Working Group are streamed live monthly. The recordings and slide decks are accessible after the webinar on this website. These webinars cover a very broad range of technical and policy related topics. At the end of 2023 they have been viewed by more than 15000 people (approximately half of the views during the live streams and the other half views being of the archives on the public GIF website). In total, the GIF webinars have reached Generation IV enthusiasts, scientists, and engineers in more than 80 countries.

These webinars are organised and hosted by the GIF Education and Training Working Group (ETWG). 

This webinar describes a methodology for surface coating technology using the DED technique. Also, optimization of the coating layer manufacturing process of LBE corrosion-resistant materials has been performed. Various property evaluations of the DED coated layer, such as microstructure evaluations, and mechanical properties, including high-temperature tensile test, general corrosion, and high-temperature LBE exposure test, have been performed. Finally, by confirming the applicability of the DED coating process, which has a coating thickness within 10% of the base material thickness in the final dimension, a plan to solve the existing problems of Code registration and post-process of newly developed materials was proposed.
Based on this study, the time required for the actual application of LBE corrosion-resistant materials will be greatly reduced. In addition, reliable and fast material development could be possible by applying the methodology presented in this research not only in the LBE environment but also in the field of material development that requires corrosion resistance or hard-facing in other industries.
