DAMCO: Accelerated Development of Corrosion Materials
Description
The DAMCO device enables accelerated assessment of the corrosion behavior of materials in a high-temperature molten-salt environment. At present, tests are carried out in LiCl-KCl media at 450°C. In the first phase of the device’s development (2022-2024), the aim is to simultaneously test numerous materials in a molten-salt environment, to enable rapid initial selection of materials. Salt and material analysis will be carried out a posteriori using various characterization techniques (ICP-OES, DRX, SDL, etc…). In the second phase of development (2024-2026), tests will be instrumented in situ to enable real-time assessment of material behavior.

Technical characteristics
Phase 1 (operational in 2024):
Up to 60 different materials (metals, ceramics, composites, etc…) can be evaluated simultaneously in a molten salt environment (molten chlorides) at high temperatures under a controlled atmosphere. Screening tests currently last 24 hours, but longer tests can be carried out if required. At the end of the tests, several types of analysis are carried out on both the molten salt (ICP-OES) and the materials (gravimetry, DRX, SDL, etc…).
Phase 2 (operational end 2025-beginning 2026):
As the project progresses, the tests will be instrumented in situ by electrochemical measurement, while other analytical techniques such as Raman spectroscopy are also being considered and evaluated. This will enable the corrosion behavior of the material/environment systems evaluated to be assessed in real time.
