5052和6061铝合金在中国南海深海环境下的腐蚀行为研究
DOI: 10.3724/SP.J.1037.2013.00143, PP. 1219-1226

Abstract:
通过实海暴露实验,研究了5052和6061铝合金在中国南海海域800和1200m深海环境下浸泡3a的腐蚀行为.采用SEM,EDS和XRD技术,分别进行了腐蚀形貌观察、腐蚀产物成分和相组成分析.结果表明2种铝合金在深海环境下均发生了很严重的局部腐蚀,表面形成了白色的腐蚀产物,腐蚀产物由Al2O3,SiO2,以及少量Mg3(SO4)2(OH)2和NaCl组成.5052和6061铝合金均在铆接区域产生了缝隙腐蚀穿孔,其中,5052铝合金还在截面形成了沟槽状腐蚀坑.在样品主表面,5052和6061铝合金主要发生点腐蚀,其中6061铝合金表面的点蚀坑深度更大,密度更高,且在800m深海环境下发生了点蚀穿孔.分析表明,随着水深的增加,5052和6061铝合金的最大点蚀坑深度先增加后降低,最大点蚀坑深度的最大值出现在水深800m左右.这是由于800m深海中的溶氧量最低,促进了局部腐蚀的发生.
