The A-DREAM project aims to develop a generic approach to accelerate the discovery of corrosion-resistant materials and coatings in extreme environments. To do so, the A-DREAM project proposes an integrated approach using: (i) the digital design of materials/coatings, (ii) the synthesis of these high-throughput materials, and (iii) the implementation of accelerated corrosion tests. Through a digital approach that will include data mining, a CALPHAD-type thermodynamic approach, and corrosion modelling, a wide range of materials and coatings will be analysed to extract targeted compounds for corrosion application. These materials will then be developed through a combinatorial PVD process to quickly synthesize many chemical compositions deposited in thin films over glass substrates. Simultaneously, HEA-type (High-Entropy Alloys) materials will also be developed under the targeted DIAMS project (through conventional or combinatorial additive manufacturing) to be tested in the corrosion devices of the A-DREAM project. Finally, these upper-scale coating developments will be conducted through Cold Spraying technology. All these processes will help cover a panel of compositions and microstructures to identify enhanced compositions of massive materials and coatings, and, on the other and, to study the effect of microstructure on the behaviour of the materials manufactured. These materials will then be tested for corrosion through the implementation of an experimental DIADEM PEPR CALL FOR PROPOSALS “Integrated devices to Accelerate the Deployment of Emerging Materials” Page 27 of 35
