Abstract Scope |
The FeCrMnNi High Entropy Alloy systems promise to yield compositions possessing the set of desired properties for next-generation molten-salt-based energy systems. However, the combinatorial quarternary composition space is quasi-infinite. The well-established manufacture and corrosion-testing methodologies for identifying corrosion resistance of one single alloy are not adapted to the investigation of such compositional space. To accelerate alloy development, a high-throughput corrosion testing system is developed, from the additive manufacturing of alloys on a build plate, to the simultaneous corrosion-testing by melting individual salt droplets of ~0.3g on each alloy. A novel cyclic-voltammetry (CV)-based automated mini-probe is developed for the in-situ quantification of the dissolved corrosion product concentrations in each salt droplet. CV analysis is automated using a heuristic code to further accelerate data analysis. This integrated platform is anticipated to only take ~1 week to assess the corrosion resistance of 25 alloys with unprecedented monitoring and data acquisition capabilities. |
