| 摘要： | A set of compatibility experiments was performed to assess corrosion susceptibility of mild steel in long term contact with UF{sub 6} cylinder chocking materials and the atmosphere. Chock materials considered included concrete, pressure-treated wood, and creosote-treated wood. Immersion tests (panels partially submerged, 1000 h, 38 C), resistance probe measurements (600 h, ambient), and cyclic polarization tests on steel in leachate solutions generated from each chock material were performed. Results indicate that the long term corrosion susceptibility of mild steel in contact with concrete and the atmosphere is at least the equivalent of -- and under some conditions superior to -- that for steel in contact with pressure-treated or creosote-treated wood. No corrosion-related limitation for concrete chocks for long term support of mild steel UF{sub 6} cylinders was identified. |
