Abstract This paper investigated the corrosion behavior of Al/CFRP (carbon fiber-reinforced plastic) and Mg/CFRP FSBR (friction stir blind riveting) joints after six-month exposure to a marine environment. It was found that Mg in the Mg/CFRP joint experienced severe uniform corrosion in most regions but not inside the crevice. Severe corrosion occurred on Al in the coupled regions due to crevice corrosion and/or galvanic corrosion. Magnesium carbonate-hydrates were identified by several characterization techniques (FTIR, XRD and XPS) as the corrosion products formed on Mg in both coupled and un-coupled regions; and dawsonite and bayerite were found on Al in the coupled regions.

搅拌摩擦盲铆接 Al/CFRP 和 Mg/CFRP 接头在海洋环境中的腐蚀行为

摘要 本文研究了 Al/CFRP（碳纤维增强塑料）和 Mg/CFRP FSBR（摩擦搅拌盲铆接）接头在海洋环境中暴露 6 个月后的腐蚀行为。发现 Mg/CFRP 接头中的 Mg 在大多数区域经历了严重的均匀腐蚀，但在缝隙内部没有。由于缝隙腐蚀和/或电偶腐蚀，耦合区域的铝发生了严重腐蚀。碳酸镁水合物通过几种表征技术（FTIR、XRD 和 XPS）鉴定为在耦合和非耦合区域形成的腐蚀产物。在耦合区域的 Al 上发现了片钠铝石和三羟铝石。
