Corrosion by liquid metals
WebAug 11, 2024 · The corrosion behavior of metals, alloys, and ceramics in liquid metals is a complex problem involving simple dissolution (chemical corrosion), electron transfer processes (electrochemical corrosion), physical erosion (when there is a swift flow of melt relative to the surface of the solid), fouling, embrittlement, and stress corrosion, and ... WebApr 21, 2024 · The steels were significantly corroded at around 823 K from 250 hours to 1000 hours, due to the depletion of metal elements from their surface. The corrosion intensity is more significant at higher temperatures. Therefore, it was not expected that any structural materials can survive in liquid LiPb at 900 °C.
