Corrosion behavior of UNS N10003 alloy in molten LiF-BeF2-ZrF4 with phosphide impurity
Source abstract
Abstract
The corrosion behavior of UNS N10003 alloy in molten LiF-BeF 2-ZrF 4 salt with phosphide impurity was investigated by static immersion test at 700 °C. Results show that an outer layer of Ni 3P and an inner layer of mixed Ni 3P and Mo 3Ni 2P 1.18 formed on the alloy surface after corrosion. The depth of both corrosion layers increased linearly with the increasing immersion time and suffered severe spallation after 400 h. Cr and Fe were depleted in the inner corrosion layer indicating the phosphide corrosion layers did not prevent the selective dissolution of active alloying elements.
