Alloys accelerated discovery for circular economy by combinatorial cold spray deposition

Leader: Tanguy Lacondemine

EC-Alloys Project Background:
Accelerated materials discovery is a crucial challenge in strategic sectors such as energy, transportation, and digital technology. Faced with resource depletion, it is necessary to rethink materials design to increase the lifespan of equipment while ensuring its repairability and recycling. The EC-Alloys project proposes an innovative approach by deviating from traditional methods of manufacturing metallic materials, combining a combinatorial approach and post-processing to create a wide range of alloys. This method allows for the rapid and low-cost production of numerous metallic composites. The objective is to determine the post-processing requirements required to transform these composites into high-performance alloys and to characterize them.

Applications:
EC-Alloys will focus on the manufacture of thick protective coatings for corrosive environments, particularly for concentrated solar power, heat storage, and nuclear energy. The project also aims to discover new alloys to meet the specific needs of the electronics industry. An important aspect of this project will be the collection and management of data to create a digital laboratory notebook, thus feeding into a predictive artificial intelligence model. EC-Alloys brings together several CEA laboratories, including DRT/CTReg/DGDE/MAPP, DES/ISAS/DRMP/S2CM/LECNA, and DRF/IRAMIS//NIMBE/LICSEN, to strengthen the pioneering position of accelerated materials discovery through combinatorial approaches.
