本論文は、海洋再生可能エネルギー機器において使用される複合材と金属ファスナーの接合部における隙間腐食を調査したものである。各種合金と複合材の組み合わせを様々な海水環境（室内浸漬、潮汐タンク、実海域バージ）で試験し、腐食の発生と形態が材料と環境に依存することを明らかにした。特にXylaneコーティングの一部には損傷が見られたが、腐食生成物の溶出は少なかった。これらの結果は、海洋エネルギー機器の材料選定と防食設計に重要な知見を提供する。
English
This study investigates crevice corrosion in composite-to-metal fastener joints used in marine renewable energy devices. Various alloy and composite combinations were tested under different seawater exposure conditions (indoor immersion, tidal tank, and field deployment). Corrosion occurrence and morphology varied with both material and environment. The findings provide important insights for material selection and corrosion protection in marine energy systems.

📄 Abstract（原文）
Marine renewable energy devices use tidal, ocean current or wave energy for power generation. These devices are fully or partially immersed in seawater during service. Advances in marine renewable energy designs are being made to incorporate modular composites and a variety of alloys. Composites of interest include carbon fiber reinforced polymer (CFRP) composites, glass fiber reinforced polymer (GFRP) composites and hybrid composites with both carbon and glass fiber types. In some cases, the composite joints are made with metallic fasteners. The geometry arrangement of the marine fasteners and composite interconnect causes occluded regions, that after some exposure time can allow crevice or pitting corrosion to initiate within the occluded region. To understand the performance of these fastened systems, a modified crevice former was used to investigate crevice corrosion for fastened samples immersed in seawater using two types of glass firber reinforced plastic, carbon fiber reinforced plastic and hybrid reinforced plastic composite plates. Several alloys were investigated: Class 8.8 carbon steel, Zn plated Class 8.8 carbon steel, Xylane coated Class 8.8, Class 8.8 with sacrificial cathodic protection, 316SS, 2507SS, AL6XN and Ti grade 2. Three exposure conditions were investigated: Immersed in seawater indoors, tidal tank with seawater and deployed at a Barge (south Florida intracoastal waterway). The composite plates deployed on the barge were coated with antifouling paint prior to assembling the samples. A number of washers coated with Xylane showed blister and breaks, but little corrosion products leached out. Corrosion was observed on Class 8.8, Zn plated Class 8.8 (but in some cases, not all Zn coating was consumed), and 316SS. The extent of corrosion and the corrosion form varied not just depending on the materials, but also on the exposure environment.
