摘　　要：研究了作为放射性废液的水泥固化体金属包装材料的Ａ３碳钢在实验地大气、水泥固化体和腐蚀液中的腐蚀情况。用失重法测定了Ａ３碳钢的腐蚀速率。在样品表面涂敷不同的涂料（环氧树脂、丙烯酸（ＰＵＲ）瓷漆、丙烷醚树脂和钛白漆等），比较其耐腐蚀性能。实验结果表明：Ａ３碳钢在贮存地大气和水泥固化体中的腐蚀速率小于１０－３ｍｍ·ａ－１，在腐蚀液中小于０．１ｍｍ·ａ－１；腐蚀液的ｐＨ值对Ａ３碳钢的腐蚀速率有影响；涂料中的钛白漆耐蚀性能优于其它涂料。The corrosion behavior of A3 carbon steel is studied by the specimens that are exposed to atmosphere,embed in cement solidified form or immersed in corrosion liquid.The corrosion rate is determined by mass change of the specimens.In order to compare the corrosion resistant performance of various coatings,the specimens painted with various material such as epoxide resin,propenoic acid resin,propane ether resin and Ti white paint are tested.The results of the tests show that corrosion rate of A3 carbon steel is less than 10 -3 mm·a -1 in the atmosphere and the cement solidified from,less than 0 1 mm·a -1 in the corrosion liquids,and pH value in the corrosion liquids also affect the corrosion rate of A3 carbon steel.The corrosion resistant performance of Ti white paint is better than that of other paints.So,A3 carbon steel as packaging material can meet the requiements during storage.
