Corrosion mechanism of iron in liquid uranium hexafluoride environment
Abstract
International audience ; Dedicated and reliable experimental setup had been designed and experiments had been carried out in order to perform corrosion experiments on pure iron in liquid uranium hexafluoride (UF$_6$) at 80°C and 3 bars. Three corrosion tests have been carried out from several hundred to almost a thousand hours. No uniform corrosion has been observed for early stages samples with nodule-facies consisting in FeF$_2$ and UF$_x$ (with 4<x<5) deposits. Those FeF$_2$ nodules grew and merged leading to the formation of an almost continuous FeF$_2$ layer. The thickness of the nodule shape / continuous layer seemed to follow a parabolic kinetics law with a final thickness about 15 µm for almost a thousand hours. Thermodynamics calculations showed that the obtained corrosion products are the most stable compounds leading to assume that Fe+UF$_6$=FeF$_2$+UF$_4$ reaction occurred. After merging, the FeF$_2$ layer contained many cracks filled by UFx. These cracks were certainly due to growth stresses within the corrosion layer.
