Effect of Graphite Coating on the Corrosion Resistance of Uranium Surface

Influence of vacuum heat-treatment on the corrosion resistance of uranium surface overlaid with graphite at 100 ℃ is studied. The results show that the graphite coat after vacuum heat treatment can protect the uranium surface. The corrosion resistance of uranium surface overlaid with graphite depends on the heat treatment time and temperature. It can be expected that the reaction product of uranium and graphite may be beneficial to improving the corrosion resistance for uranium surface.
