Abstract Scope |
Aerospace vehicles and the boilers of off-shore industrial rigs that operate near the ocean or desert are exposed to salts that can melt at high temperature and produce hot corrosion, which reduces the service life of the component or vehicle. Corrosion resistance of materials in molten NaCl-Na2SO4 salt is achieved by formation of dense protective oxide film on materials surface, which prevents further corrosion of materials underneath However, the corrosion database for NaCl-Na2SO4 molten salts is still limited. Further investigation for reliable selection of compatible materials is needed. High Entropy Alloys (HEAs) have emerged as attractive candidate materials due to their good corrosion resistance and mechanical properties. The present study will focus on the influence of bi-axial stress on the corrosion behavior of Al0.1CoCrFeNi HEAs in NaCl-NaSO4 molten salts. |
