摘要: Ｎｉ－１３Ｃｒ－０．５Ｃｅ合金在５７５℃Ｃｌ_２－Ｈ_２Ｏ混合气氛中的腐蚀行为涂江平，李志章，毛志远（浙江大学杭州３１００２７）１引言关于合金在干氯气或含氯的氯化气氛中的腐蚀行为已有报导［１～３］，而在实际生产中，液氯经雾化后往往存在少量水份，使腐蚀环境变得复杂，尤其在高温下腐蚀条件进一步恶化［４］．高温氯气环境中少量水蒸气的存在对合金腐蚀行为的影响是复杂的．在５５０℃以下时水蒸气会加速镍基合?...

Abstract：This paper describes the chlorination of Ni-13Cr-0.5Ce alloy in Cl2-H2O gaseous mixture at 575℃.The reaction product films were examined by SEM, XRD and XPS. There were Cl2, HCI, H2O, O2 and HOCl in the gaseous environment. The corrosion products consisted of volatile chlorides, oxychloride and oxides. Addition of Ce tO Ni-Cr alloy improved the overall corrosion resistance because of the formation of stable oxides but increased the depths of internal chlorination. The reaction rate followed approximately the parabolic law until the product film reached a steady thickness after which there was a linear decrease in weight change with time. The corrosion rate of Ni-Cr-Ce alloy in the ined Cl2-H2O(g) atmosphere was greater than that in dry chlorine.
